TBEAM stuck in loop (deep sleep for zero seconds) #15

From @claesg

TTGO T-BEAN stuck in boot loop.

Yesterday it was running fine (on 0.1.0) and this morning it was dead. I connected it to arduino ide and the serial monitor and noticed that it was looping: k⸮⸮)Setting GPS power=0 ets Jun 8 2016 00:22:57

Setting bluetooth enable=0 I tried to reflash meshtastic but it did not help. I had to flash 'wifi scan' example from the ide which it accepted and it was working. I then flashed meshtastic and this time it is working as expected. Maybe the log above can tell what happened?

Sorry about the strange formatting.

Super useful. Was it repeating this in a loop at high speed, rebooting rapidly, or was it pausing for a long time while in deep sleep.

geeksville commented 4 years ago

oh - I see the problem:

Entering deep sleep for 0 seconds

That number should never be zero. I'll check the code and fix this later today.

geeksville commented 4 years ago

ooh - yeah - I added the deep sleep parameter to the preferences we store in flash, but didn't think about that people who had installed older builds would get zeros for that value. The fix will be easy.

That is great!
