Board will not go into OTA mode

[patrickdijusto]

I got the board working just fine out of the box. I downloaded all the files needed to run "Hello". I compiled it and uploaded it just fine.

But now the board will not return to OTA mode. I shut it off, press and hold the center button, turn on the board, and nothing happens. The edisplay still shows the "Hello my name is..." graphic.

I have tried this while powering the board via USB from my laptop, and via USB from a fully charged power brick. When I flip the board's switch to ON, a red LED at the center of the lower edge of the reverse side of the board blinks about once every 7 seconds, in sync with the blue LED on the ESP32. That's all that happens.

When I flip the switch to OFF, the red LED at the center of the lower edge of the reverse side of the board blinks about 5 times per second. THe blue light does not blink at all.

I have tried multiple USB cables and power sources. Nothing works to put the board into OTA mode.

I do not have the skills to solder connectors to the board. What can I do?

Hi @patrickdijusto,

Could you tell us if the screen refreshes when you slide the switch from off to on?

You are also able to reflash Badgy using the pads on the PCB without soldering, do you have a USB-Serial adapter?

The screen does NOT refresh when I flip the switch from on to off or off to on.

I used the hello program from this git repo. The only thing I changed in the hello program was my name.

Thanks for the info. Could you share with us the compile settings used in Arduino? The blue LED on the ESP blinking every 7 seconds means it is crashing and resetting. Since the name is the only change to the code you made, it is likely to be either a compile settings error, or a hardware related issue (e.g. insufficient USB power, loose display connector, shorted components, etc.)

To flash your Badgy with a USB-Serial adapter, follow the wiring information in our documentation and push the pin headers against the board like so (you may have to scrape the surface a little for better contact):

For what its worth - in case it helps anyone else and/or maybe is the case here - yesterday I accidentally compiled a new code base with ESP8266 set as the board in the Arduino settings, instead of NodeMCU ESP-12E :((( My experience was similar to what you describe Patrick - board just seemed dead except for the odd blue LED flash. Unfortunately the only solution was to solder wires onto the board and reflashing with an FTDI.
