- Sun Jun 12, 2016 5:57 pm #49089 Posting it up.

OK, so the issue is I have a esp8266 breakout board that i am using for testing. I'd like to be able to program OTA because its faster. However, when try to upload OTA it says "upload done" in the arduino IDE, but the esp8266 appears to enter bootloader mode. Pressing the reset button on the esp8266 board doens't bring it back out of bootloader. It stays like that until i upload new code via serial.

I have used this with ESP12 modules that i've solderd on to PCBs in the pat without issue... but it doesnt seem to work on the huzzah breakout. Anyone familiar with this issue?

- Mon Jun 13, 2016 7:43 am #49114 I doubt that the OTA problems you faced are related with the hardware.
It is most likely a software issue. What is the kind of firmware do you use ?

- Mon Jun 13, 2016 11:02 am #49120 Yes most ESP8266 Modules are the same, the only difference normally is pinout and how the bootloader operates, so as long as your able to load code, its most likely a software issue.

- Mon Jun 13, 2016 5:50 pm #49148 I am pretty sure it is not a software issue.

Here is a schematic i am using using an esp12 module. It works with OTA programming.

The huzzah breakout board does not.

I have uploaded the same code to each board. After i upload, the huzza product will upload, but when it resets it resest into bootloader. With my own ESP, it resets into normal mode.
