The debug crash log showed it seemed to be identical to a normal power-on start. Seems like the module rebooted itself a dozen times a day. After trying everything - more than a dozen firmware changes painfully loaded into the car module, I finally found the problem: the module was rebooting, it was just incorrectly reporting a reboot every time the cellular signal recovered. Good grief.</div><div><br></div><div><span style="font-size: 13px; ">Anyway, back on track again now.</span></div><div><span style="font-size: 13px;"><br></span></div><div><span style="font-size: 13px;">Today, I've pushed to github my backlog of 36 commits, totalling 1.5MB! This makes the first 'alpha' release of v2.5 code. A summary of the (extensive) changes:</span></div><div><span style="font-size: 13px;"><br></span></div><div><ol class="MailOutline"><li><span style="font-size: 13px;">Tesla Roadster Experimental Speedo<br><br>No longer experimental. Now on bit#0 of permanent feature #13. Old feature #0 no longer used.<br><br></span></li><li><span style="font-size: 13px;">Drive and Charge logging</span><br><br><span style="font-size: 13px;">Server as well as vehicle changes made to support this. Setting bit#1 of permanent feature #13 will turn on logging of drives. Setting bit#2 of permanent feature #13 will turn on logging of charges. If enabled, at the end of each drive/charge the logging system will attempt to upload a *-Log-Drive or *-Log-Charge record with details on the drive/charge. It can store up to 6 such records without server connectivity. The records themselves can be downloaded as historical data using either the HTTP or OVMS protocol APIs. To implement this, a new 'h' style of historical data submission has been supported by the server - this allows for acknowledgement of successful data reception by the server, as well as a time offset for cases where the data cannot be immediately transmitted.</span><br><br></li><li><span style="font-size: 13px;">Cooldown</span><br><br><span style="font-size: 13px;">Core support has been added for 'cool down' charges, and implemented in the Tesla Roadster module. Cooldowns can be initiated by the 'COOLDOWN' SMS message, or by server command #25.<br><br></span></li><li><span style="font-size: 13px;">Tesla Roadster event notification<br><br>A few changes have been made to the Tesla Roadster module to try to make it notify the server of major events immediately (such as charge mode changes, charge limit changes, etc).<br><br></span></li><li><span style="font-size: 13px;">Server support for Authentication failures<br><br>The server code has been extended to send a PUSH notification in the event a vehicle authentication fails. The server will also send another PUSH notification if the vehicle subsequently authenticates successfully.<br><br></span></li><li><span style="font-size: 13px;">Distance utility function<br><br>Courtesy of Tom, a distance utility function to calculate the distance between two GPS locations and tell if they are closer than a pre-set limit.<br><br></span></li><li><span style="font-size: 13px;">NET fixes<br><br>Added a few more checkpoints and sanity checks for NET layer data, to try to avoid crashes and overflows.<br><br></span></li><li><span style="font-size: 13px;">Debug Crash Reason reporting<br><br>Bug fix to avoid duplicate reports of debug crashes every time the server connection is made. As a side-effect, normal first-time boot-ups will no longer be reported (by design).<br><br></span></li><li><span style="font-size: 13px;">Stub ACC implementation<br><br>I've done a lot of work on ACC in my own branch, but not committed to head, yet. I need some more time to do further testing before I'm ready to release. For the moment, there is a minimal implementation the does the ACC location mapping, and is capable of seeing if the car is within range of an ACC location. You can also configure the ACC locations and parameters. More on this will come with v2.5.2.<br><br></span></li><li><span style="font-size: 13px;">Documentation<br><br>I've updated the Tesla Roadster user guide, as well as OVMS Protocol guide, for the above.</span></li></ol></div><div><br></div><div><span style="font-size: 13px;">I haven't built binary firmware for this yet, as it is so new and raw. It is running in my car, and now seems stable, but needs more testing before prime-time release. If you want to try it, you'll need to build from source. Then, set feature #13 to 255 (to enable all opt-in features) and you should get a digital speedo (Tesla Roadster v2.x cars only) as well as logging to the server of both drives and charges.</span></div><div><span style="font-size: 13px;"><br></span></div><div><span style="font-size: 13px;">I'm over the hump now, and hopefully v2.5.2 can come within the next week.</span></div><div><span style="font-size: 13px;"><br></span></div><div><span style="font-size: 13px;">Regards, Mark.</span></div><div><span style="font-size: 13px;"><br></span></div><div><div><div>On 5 Aug, 2013, at 12:38 PM, Mark Webb-Johnson <<a href="mailto:mark@webb-johnson.net">mark@webb-johnson.net</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><br>Just a short note on progress.<br><br>I managed to get a lot done over the weekend. Working with Tom on some misc functions for ACC, and all looks good so far. Basic ACC location management is done, and I've worked out a way of using base64 to encode the ACC structures into our limited 32byte parameters. Seems to work quite well - very lightweight (we already have base64 for the comms protocol), and very expandable.<br><br>I'm now just trying to pull everything together to get cooldown working. Once that is working, I'll commit (even in that unfinished form). Logging (drive and charge) is already done, and part of this. Flash space is getting concerning (approaching 95% now, for experimental with all vehicles), so we'll have to address that once ACC is out.<br><br>I'm getting a rather large backlog of other requests now (put aside due to ACC work, trip to USA for TESLIVE, and horrendous day job hours). Once the basic ACC is committed, I'll be able to spend some time to try to work through that. Apologies for the delays (to anyone waiting for me).<br><br>Regards, Mark.<br><br>_______________________________________________<br>OvmsDev mailing list<br><a href="mailto:OvmsDev@lists.teslaclub.hk">OvmsDev@lists.teslaclub.hk</a><br>http://lists.teslaclub.hk/mailman/listinfo/ovmsdev<br></blockquote></div><br></div></body></html>
