Android code for OVMS
by Mark Webb-Johnson 13 Dec '12

13 Dec '12

It appears that we're in a mess with the Android code base. The Android project Sonny had worked on containing updates to the OVMS Android App has been accidentally deleted, and the latest updates to the code lost. The NAS backup arrangement that Sonny had in place has also failed, and there is no backup. Sonny apologizes, and has tried hard to recover the files, but cannot. He is also still tied up with work commitments, and can't help much for the next month or two. We still have the code base in github, but that is quite old as it has not been updated with the improvements made in recent months. Primarily the settings screen, partial support for groups, and support for tablets. It is the tablet support that is causing problems with new high-res phones (as it is incorrectly identifying these as tablets) - I suspect that the settings code is the main thing we want to retain. I have tried to reverse-compile the Android code from the APK in the marketplace, and while the resulting code looks pretty good, the resources are not reverse-compilable, and look like they would take a significant amount of work to repair. My approach has been to take the github version, compile it, decompile it, and compare that with the decompiled version of the latest android market APK - applying patch duffs where necessary. The code looks good, and seems to only need minor tidy-ups. But, the resources are a mess. It seems the decompile process retains code symbols, but not resource symbols. The resource IDs and tags end up as numbers. I'm really not familiar with Android development, so am not sure how feasible that approach would be. It looked very easy and successful to start with. So, we are faced with a decision: 1. Someone more experienced with Android development comes up with a brilliant solution to finish off the reverse compilation of the APK to get back the latest version. I don't mind stepping in with the 'donkey work', but I really don't know where to start. What are those "R" class files - they look like they may be the key? 2. We start again with the code as it was a few months ago, and try to take it forward from there. 3. We investigate cross-platform development environments that could perhaps give us a more unified appearance across the the different platforms, as well as support for Windows Phone and others. What do people think? Mark

1.5.1
by Mark Webb-Johnson 28 Nov '12

28 Nov '12

Firmware 1.5.1 has been built for all platforms and is now on github. The primary focus of this release has been adaptive reporting and simplifying provisioning. Due to the drastic reduction in cellular data usage with this release, and improvements in cellular connection handling, this firmware is recommended for all end users. Github issues addressed (since 1.2.9) are: #93 Car: Notify server/app when charge has completed #92 Try TCP reconnect, rather than full GPRS re-init, if server connection fails #90 AP via SMS #89 Report GSM operator #86 Get ICCID from SIM during startup #84 Detect lack of comms between PIC and modem #82 Adaptive Reporting #80 Make GSMLOCK use short service name #79 SMS/PUSH notify if alarm is activated #78 can_poll0 100 vs 102 check #77 Option for GSM Network selection #76 SMS HELP command #75 Car: Basic (stub only) Renault Twizy Support #74 Car: SETUP (DIAG) mode for firmware #71 Car: Send line voltage level back to server #70 Car: Send hardware version along with firmware version #69 Wakeup temperature subsystem when car is woken up #58 Car: Strange range when low on power #57 Car: Motor temperature overflow Regards, Mark.

Adaptive Reporting
by Mark Webb-Johnson 12 Oct '12

12 Oct '12

The adaptive reporting now seems as good as it can be. Reduction in cellular data usage is pretty dramatic, and down to about 1/6th of what it was before. Something like 350KB/month (down from 2+MB/month before). Below are some annotated log files from the server for 24 hours with my car running 1.3.8. As well as generally slowing down the reporting interval, and only sending changed records, the code also has re-worked algorithms for linear back-off of data connections. If it loses connection to the server, it will also try to reconnect at the TCP level (if possible) rather than blindly re-establishing the GPRS link, as the cellular providers round-up data usage at the GPRS link level, not the individual TCP connection level. Overall, we try to handle marginal network GSM/GPRS connection areas better. I think this is good to go, so I will build this as end-user suitable firmware v1.5.1 (I live in China, so don't like anything with the number '4' in it), and release later today. Regards, Mark.

GeoSIM
by Mark Webb-Johnson 11 Oct '12

11 Oct '12

Just thought I'd share some results from the geosim (hassle free sims) test that we've been running. We have had the SIM in a roadster on AT&T network in USA, for the past two weeks. Between 27th September and 11th October (15 days), we were billed a total of US$1.39 for data and US$2.95 for SMS. The data was billed at 1.36MB. The SMS charges were for 6 international SMS messages sent by the module on 27th September (kludgy setup with some mis-steps). With my new web-based sms provisioning system that would have been US$0.00. Assuming half the month, the full month data charge would be US$1.39x2 = US$2.78/month, for around 2.72MB. We estimate around 60KB a day (1.8MB/month), so this is a little higher, but the mobile providers round-up connections to the nearest 10KB, so this is to be expected. Yearly, the charges for this SIM should be US$0.00 to setup (or if you do it locally, perhaps US$2.00), then US$33.36 + US$10.00 yearly fee = US$43.36/year. With our new adaptive reporting code in the latest firmware, I'm seeing my data usage go down to about 1/6th. 60KB/day has gone down to <10KB/day. Now, the mobile providers round-up so in poor cellular coverage areas that is not going to be as good, but I think we'll see at least 50% savings. Overall, this seems pretty good to me. We lose SMS control, but the SIM and service itself seems fine. Hopefully the web-based provisioning system should simplify that. We're going to continue the test with v1.5.1 firmware (should be released tomorrow), to see how well the new adaptive reporting algorithms translate to actual usage with the cellular providers rounding up connections to 10KB. Regards, Mark.

SMS Provisioning from www.openvehicles.com
by Mark Webb-Johnson 10 Oct '12

10 Oct '12

I've released the code for SMS provisioning from www.openvehicles.com to the live site. The way this works is as follows: We use a bulk SMS service to send/receive SMS messages, globally. The My Account page on www.openvehicles.com now has the ability to enter a phone number against any of your vehicles. If entered, this is the phone number of the SIM card in the module. A SMS Provisioning form is now provided (reached by the little icon on the My Vehicles page). That form allows the user to enter all the information necessary to provision the module. If the user chooses firmware <= 1.3.5, then the provisioning mechanism will send a REGISTER sms message (to register the global sms provider as the owner), then PARAMS (to configure the module parameters), then optionally PASS (to change the module password, if requested). Each of these messages will result in an SMS reply from the module to the bulk sms service (more on this later). If the user chooses firmware >= 1.3.6, then the provisioning mechanism will send a single AP sms message with all the provisioning parameters. There will normally be no reply to this message. Should the module reply to any SMS messages from the bulk sms service (particularly in the case of firmware <= 1.3.5), then those will be delivered back to us and we will auto-deliver them via eMail to the registered owner. This mechanism is really designed for those using the hassle-free global SIM card we've partnered with. Provisioning it with this mechanism should be very very simple. Open Vehicles is swallowing the cost for these SMS messages. Hopefully it will not get out of hand, and we've got a paypal donate button up there for anybody that uses it and finds it useful. Regards, Mark.

1.3.8
by Mark Webb-Johnson 08 Oct '12

08 Oct '12

I've built firmwares and committed to github for car firmware 1.3.8. Changes include: 2012-10-07 1.3.8 Firmware 1.3.8 - getting close to the 1.5.1 release #92 Try TCP reconnect, rather than full GPRS re-init, if server connection fails #82 Car: Adaptive Reporting 2012-10-01 1.3.6 Firmware 1.3.6 #90 AP via SMS #89 Report GSM operator #86 Get ICCID from SIM during startup #82 Adaptive Reporting #84 Detect lack of comms between PIC and modem #80 Make GSMLOCK use short service name 2012-09-14 1.3.5 Firmware 1.3.5 #79 SMS/PUSH notify if alarm is activated #78 can_poll0 100 vs 102 check 2012-09-12 1.3.3 Firmware 1.3.3 #77 Option for GSM Network selection #74 Car: SETUP (DIAG) mode for firmware #76 SMS HELP command #75 Car: Basic (stub only) Renault Twizy Support #71 Car: Send line voltage level back to server #70 Car: Send hardware version along with firmware version ### Make QC config use TMC server 2012-09-02 1.3.1 Firmware 1.3.1 The following issues have been addressed (since 1.2.9): Tidy-up for charge notifications #57 Car: Motor temperature overflow #58 Car: Strange range when low on power #69 Wakeup temperature subsystem when car is woken up The biggest changes are issues #92 and #82 regarding reducing the GPRS data usage. In tests so far, the v1.3.6 (which made about half the optimisations planned) reduced this to about 1/3rd of previous levels, and v1.3.8 (which completes it) should bring this down even further. I'm hoping for around 10KB/day average, but it really depends on how much you drive, charge and use the apps. See the screen-shot chart below for details (I put in v1.3.6 around 1st October, and v1.3.8 just today 8th October). The reported bug regarding module rebooting (and hence losing the experimental speedo feature) appears to have been fixed for me. This version does try to recover the TCP/IP connection to the server without a GPRS restart (which is costly as mobile providers round up their data usage), and hopefully that is still reliable. This version also includes a new SMS provisioning method (issue #90). This allows a single SMS message to provide the module password (for authentication) and all parameters to be set in the module. I've been working on a website form that will allow you to enter these values (with appropriate defaults and online help) then use a bulk sms service to provision the module with just one low-cost SMS message that works internationally. It is looking to be a very simple way of configuring the module - the only drawback being Open Vehicles has to pay for the SMS charges (but we'll live with that, given the simplicity, and hope for the occasional donation to cover it). As always, I'd be grateful for help testing this in cars. Regards, Mark.

1.3.1
by Mark Webb-Johnson 01 Oct '12

01 Oct '12

Car firmware 1.3.1 is in GitHub now. I built all variants to .hex files, and source is there for the adventurous. Tom: can you help setup end-user instructions of this? All outstanding car issues recorded on github have been resolved and closed with this version. It has been running in my car for a few days, and seems fine. I did a few different charge-interruption tests, and they all alert as expected. I'm gonna wait a few days to allow you guys some time to try it out and report any issues (hopefully none). I'll then announce it as generally available. Due to the enhanced modem control, linear connection backup algorithm, bug fixes, and new improved notification algorithm, this will be a recommended update for all users. Regards, Mark
