Hi,I am trying to use the code you posted for server and client. I get the following error on the client module on the serial monitor of the Arduino IDE:


ets Jan 8 2013,rst cause:4, boot mode:(3,6)

wdt reset
load 0x4010f000, len 1264, room 16
tail 0
chksum 0x42
csum 0x42
~ld

I'm not sure if it makes a difference, but the specific model I have has a built in regulator, it looks like this http://www.gearbest.com/transmitters-re ... Apy_8P8HAQ

Maybe you have bad configs already stored in the Flash.
Is the crash happening on the Server or the Client ?
Did you try to erase the whole Flash before uploading the sketch ?

It's crashing on the client, server seems to be running fine. I'm not sure how to check for bad configs in the Flash. How should I go about erasing the Flash?

Code: Select allesptool.py --port /dev/ttyUSB0 erase_flash

For the esptool binary that comes with IDE, I think the "-ce" for erase has been added 3 weeks ago.
