Instability on GSM

Hi, I let my ovms run on GSM for a while and it's not very stable. I'm not sure if wifi is better or worse but here's a log starting from a reboot with the button, connecting, disconnecting and crashing. My esp-idf looks up to date: commit 88ab5d4830e2eeb24fbae1d5f7d66a2e33bdbde0 Author: Stephen Casner <casner(a)acm.org> Date: Sun Oct 22 00:25:10 2017 -0700 Welcome to the Open Vehicle Monitoring System (OVMS) - Async Console I (605) simcom: State: Enter PoweringOn state I (605) simcom: Power Cycle D (1485) SIMCOM tx: 41 54 0d 0a AT..

Network Manager Ideas
by Mark Webb-Johnson 13 Dec '17

13 Dec '17

I’ve had lwip pppos (via SIMCOM) running on my desk overnight, and it seems stable. Of course, we’ll need to do some fine tuning based on feedback in the field, but at least PPP connections can be brought up and down cleanly, and that is the base capability needed for more sophistication to be built on top. The OVMS v2 client code also seems good. With DEMO car, it is not producing too much data, and seems roughly comparable to v2 usage. For example, here is the start of one of my recent sessions (log level info): I (17600) simcom: State: Enter PoweringOn state I (17600) simcom: Power Cycle I (23660) simcom: State: Enter PoweredOn state I (42770) simcom: State: Enter MuxStart state I (42770) gsm-mux: Start MUX I (42780) gsm-mux: Channel #0 is open I (42780) gsm-mux: Channel #1 is open I (42790) gsm-mux: Channel #2 is open I (42800) gsm-mux: Channel #3 is open I (42810) gsm-mux: Channel #4 is open I (43750) simcom: State: Enter NetWait state I (53830) simcom: CREG Network Registration: RegisteredRoaming I (54750) simcom: State: Enter NetStart state I (55890) simcom: PPP Connection is ready to start I (56750) simcom: State: Enter NetMode state I (56750) gsm-ppp: Initialising...

So, now to think about how to manage this in general. To make it easier for the end user. Here are some notes/thoughts: We continue to use events and scripting for fine-tuned control. For configuration, we offer options to set values and have those automatically actioned at startup. Examples: If a vehicle type is configured, then automatically start a vehicle module of that type. If a v2 configuration is present, then automatically start a ovms server v2 connection. For networking, we have the network manager component. The idea here is to extend that to provide network link logic. Examples: If wifi comes up, then sleep the simcom modem If wifi goes down, then wake up the simcom modem The above configuration settings can be simply mapped to v2 protocol features/parameters. While Config parameters are currently registered and visible (MyConfig.RegisterParam), instances are not. That makes it tricky to see what config instances are available. In some of the code, we document the instances as comments after the parameter is registered. My suggestion here is to add a MyConfig.RegisterInstance to allow for instance registration (with a default value). If the instance does not exist, then it would be created with the value set as per the default. That would then make it visible to the user. The only downside to this is that the default value can’t later be changed. What do people think? Does that make sense as an approach? Implementation should not be difficult. Regards, Mark.

Emacs

Working with Steve and Greg, we’ve got a very minimal emacs style editor running in the latest code just committed. It is based on the openemacs project (which is based on another project called kilo). Both attempt to get an editor into 1024 lines (ours is 1458; but we put braces on lines of their own). As a side-requirement of this, Steve has now implemented a way for executing commands to switch into a mode where they can get raw keyboard input. That is useful for several other things (other than WYSIWYG editors). Command is: vfs edit <filepath> A few caveats: I haven’t implemented search yet. It should come at some stage. Log messages currently screw up the screen. @Steve will try to work out a way to suppress/discard these during input feedback mode. In the meantime, Control-L (screen refresh) is your friend. Control-X Control-S doesn’t work on the async console. I think something is swallowing the Control-S. But Control-X S/s works just fine. Control-X Control-C sometimes crashes the ssh console. I get "Bad packet length 3324299854” and then all goes to hell. Telnet behaves very well, and seems to support both Control-S and Control-C properly. CR/LF handling seems wrong. Behaves strangely when pasting. It is pretty slow to paste characters. OK for writing/changing small scripts, but painful for much more. It works on my terminal (OSX iTerm2). It might not work on yours. ANSI/VT100 is a mess. The way we get terminal size (rows, columns) is kludgingly elegant. Memory usage is about 2 to 3 times the size of the file being edited. Seems ok for script files, but beware. Syntax highlighting does work. Very cool. Of course, this means we need syntax highlighting for ovms scripts. Enjoy, Mark

scp is implemented
by Stephen Casner 10 Dec '17

10 Dec '17

I have extended the SSH server in console_ssh to support SSH session type "exec" in addition to the original "shell" session type. This allows the client ssh command to be followed by a command to the executed on OVMS: auge1221> ssh ovms vfs ls /store ovms_config scripts events testdir auge1222> It also allows use of the client's scp command to transfer files to or from OVMS. The clients scp command starts an ssh session and passes along an scp command to be executed on the server's end. On a Unix-like system the server would execute the scp command as a separate process, but on OVMS I have implemented the scp protocol within console_ssh. So, for example, I can use scp to fetch my startup script so I can edit it to remove the extra command I added to set the logging level for ssh while I was debugging and then write back the updated script: auge1224> scp -r ovms:/store/events . startmeup 100% 72 0.1KB/s 00:00 auge1225> scp events/system.start/startmeup ovms:/store/events/system.start/ startmeup 100% 56 0.1KB/s 00:00 auge1226> In these examples you see that I am using public key authentication so I don't have to enter a password. Secure and very convenient! The SSH implementation is a bit slow doing the public key calculations so there is a pause of a few seconds as each command begins, but then the files are transmitted expediously. I have not attempted yet to do tuning of build options for wolfssh for speed and memory usage. I have also not figured out yet how to perform the rekeying procedure with this wolfssh library. Because the rekeying is not implemented properly some data may be lost when it occurs. However, rekeying will be triggered after about 1GB of data transfer, so it seems unlikely that we will hit that trigger right away. For those who have been wondering when this would be completed, sorry for the delay. The scp protocol is somewhat crude and there is no document to specify it which meant I had to do experiments to figure out the right actions at each step. Finally I found the OpenSSH implementation on github so I could RTSL. After that testing all the corner cases took a while. I'm sure you all will let me know if you find problems! -- Steve

Fix to esp-idf for adjusting logging levels
by Stephen Casner 10 Dec '17

10 Dec '17

If you have observed that sometimes when you try to adjust logging levels using the OVMS command "level" that the change is not effective, the explanation is that the logging code in esp-idf uses a cache to speed the level lookup but the call to set the level did not update the cache. I've fixed that in openvehicles/esp-idf just now. -- Steve

Notifications concept draft
by Michael Balzer 10 Dec '17

10 Dec '17

Some thoughts about how to implement vehicle notifications and data logging. Please check & comment. Concept: - handle all unsolicited transmissions from vehicles by commands - vehicle module signals event if a transmission is due - … with event data = command line to generate output - listeners retrieve the transmission content by executing the command - queueing for async delivery is done by the listeners (i.e. through BufferedShell) → any shell command can be used for transmissions → all transmissions can also be generated on the shell / by script → all transmission output can be sent to any channel → data logging on SD can be done transparently by the system Interactive consoles can output unsolicited transmissions by event type according to the current log level. Events: "send.info" → send text notification "send.alert" → send text alert "send.data" → send data record (CSV, content part of v2 MP) Scheme: MyEvents.SignalEvent("send.<type>", "command [args]"); Examples: MyEvents.SignalEvent("send.info", "stat"); MyEvents.SignalEvent("send.alert", "xrt batt status"); MyEvents.SignalEvent("send.data", "xrt log RT-BAT-C"); → command output: H,RT-BAT-C,4,86400,1,1,4025,3675,4045,5,14,14,19,1 Regards, Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 833 5735 * Handy 0176 / 206 989 26

Are there any lists of issues/actions/milestones remaining before- approving the factory to begin more/volume production- per car model issues ? Looking forward to being able to order hw for a LEAF, and integrate OVMS ! -Chris
