ESP8266-01 Returns to Bootloader mode
Posted: Thu Mar 03, 2016 4:17 pmHi,
I've been trying to make two ESP8266 boards to talk together. I've updated the FW to SDK 0.9.5 - AT 0.21.0.0 and I have found that sometimes the boards do not work after AT+RST or just when the board is restarted (hard). The only thing that works is BAUD 76800 and it shows "cause 1 boot mode 3,6". I have to reflash the .bin file couple of times using the FLSH DOWNLOAD TOOL 2.4 couple of times before it works again. When it works I reset the BAUD TO AT+IPS=9600, connect using the BAUD, work for a bit and it craps out again if the board is reset or power is cut. I have two ESP-01 units and they both behave the same with the same SDK.
Has any one seen this before? Any advice would be appreciated.
Example Log:
Thanks
