I have a particle boron that has been in service since 2021. It had been running the firmware (a weather station program) successfully on OS 2.0.1 without any problem until a few weeks ago. The device stopped transmitting and went into listening mode (blinking dark blue). This has happened a few times in the past, and I was always able to resolve the issue by resetting the boron by holding down the MODE button and tapping RESET. However, this time I could not get it out of listening mode. I brought the boron home and hooked it up to my computer and executed a device restore over USB (using Chrome web interface) to OS 2.0.1 and flashed tinker. My boron liked this and was happily connected via LTE and breathing cyan. However, when I go to the web IDE and flash my weatherstation firmware, my boron was not happy. Web IDE successfully compiled the code (which makes sense because this is the same code I have been using for 4 years) and reported that the code was successfully flashed to the device. However, after receiving the code, my boron “breathes” red three times, then starts flashing green (connecting to network), then back to “breathing” red three times and the cycle repeats. The only way I can break the cycle is to put the device in DFU mode and then do a device restore over USB (using Chrome web interface) to OS 2.0.1 and flash tinker.
Anybody have any ideas on what is happening and how to fix this issue?
Breathing red isn't a standard color combination. I would enable USB debugging and see if there are any log messages generated:
SerialLogHandler logHandler(LOG_LEVEL_TRACE);
Hi Rick - I added the code you suggested. Please find below the output of the serial monitoring text. As you can see it keeps reapeating each time the boron resets (after it breathes red three times). I have no idea what this means. Can you please tell me what is going on?:
