Using ESPlorer I am able to program different ESP8266 modules from 2 different PC's (win 7 and win 10) both work fine. After working for a while with my NodeMCU (http://www.aliexpress.com/item/New-Wire ... 90854.html) suddenly some characters are wrong when sent to the NodeMCU from either of the 2 PC's. My other ESP modules on both PC's continue to function fine.
for instance sending
"node.info"
effectively gives
"=no`e.info )Á"
in the output window of ESPlorer.
I tried reflashing, different versions of the firmware multiple times but nothing helps.
An observation is also that I need to flash twice for the flash to be sucessfull. The first time always gives a timeout. This does not happen with other modules.
I hope someone knows something
regards,
Koen
