The new OTA updates rolled out for cellular devices seems to be causing problems with my electrons. When flashing OTA it goes through the magenta blinking but then the RGB either goes solid magenta for 2-3 minutes before restarting the device, or the RGB will go completely off for 2-3 minutes and w…

Sounds similar to another guy on here also using a 3rd part SIM and trying the update with issues. @rickkas7 Is going to test this on his end to see if the 3rd Party SIM is causing issues. For him the Particle SIM worked.

do you have a link to the thread? I did a search and I did not see it.

[image] Electron power-on connectivity issues with 0.8.0-rcX Troubleshooting Tinker is built for 0.4.6 or something like that. But I can try using an 0.8.0-rc4 binary and a 3rd-party SIM tomorrow. I used the Particle SIM.

I have tracked this down somewhat more. I found that this problem only happens when my code contains functions. For example: if (pump1 == true){ pump1timer(); } if I comment out all functions throughout my code the problem goes away, and my OTA updates work again as normal. Also note, t…

I have also manually downgraded to firmware 6.4 (verified with CLI) and then compiled code for 6.4 with the web IDE and flashed my code locally through serial and after completing this, the OTA updates still have the same problem. (also tried 6.2 after trying 6.4)

The symptoms you are experiencing are usually rooted in the application firmware locking shared resources when employing multi threaded tasks (e.g. SYSTEM_THREAD(ENABLED) or Software Timers). In such cases the attempted OTA update and one of the application threads demand a shared resource and dead…

@ScruffR thank you for your help. Maybe I’m not understanding the way code is flashed to the electron, but I tried some tests, I flashed the suspect code to the electron locally with CLI and then try to flash a different user code OTA, it will work, but if I flash suspect code with CLI locally and …

[image] ScruffR: (e.g. SYSTEM_THREAD(ENABLED) or Software Timers). Also, I am not using system_thread (enabled)

How big is the binary of your `“supect” code and how big were your other test binaries? Try flashing this sketch and then watch what the serial log output shows during OTA update // set APN as needed for 3rd party SIM STARTUP(cellular_credentials_set(APN, "", "", NULL)); SYSTEM_THREAD(ENABLED) Se…
