Firmware V5 Datalogger web api crashes #59

Open BevDan opened 6 years ago

BevDan commented 6 years ago

I have tried to use the latest versions of Firmware V5 Datalogger in the freematics one device, I had an older version that was pretty much working, however I have upgraded to the latest version and now have several issues: Firstly if I try to get live data without an active obd connection (Not having turned the keys on so the computer is still shutdown, however I have 12v supply so not getting brownouts) and I issue the live request http://192.168.4.1/api/live I get:

`[8193] Request path: api/live Guru Meditation Error: Core 1 panic'ed (LoadProhibited) . Exception was unhandled. Register dump: PC : 0x40101e30 PS : 0x00060430 A0 : 0x80107a89 A1 : 0x3ffd1520

Rebooting... ESP32 240MHz 4MB Flash MEMS...OK ACC Bias:0.04/0.02/-1.03 SD...15079MB HTTP Server...AP:192.168.4.1 OK OBD...NO Standby ACC Bias:0.04/0.02/-1.03 ` And now when I try to get the data over the network I get either blank webpage in Internet Explorer, or and error about unrecognised format when I do the request from within Visual Basic for Applications (MS Access).

I also had to reinstall the Arduino builder to get this version to compile and build properly.

The freematics web page indicates that the most recent version of Arduino builder should be 1.0.12 but the most offered link at sourceforge points to version 1.0.8. I just keep reinstalling version 1.0.11 when I have build troubles

(disregard this comment, see later) Dan, regarding the blank page, could you have a look at issue #52 ? It might be related.

As for "live" not working without an OBD connection, I might agree that crashing is not a good thing, but how would it work in practice? Best option here, adding a check for STATE_OBD_READY and then returning with an empty page / error message.

Any news on this?

Crashes in handlerLiveData when trying to print GPS information, which might not yet be available.
