Hi all,
I am a more or less complete newbie with electronics and micro-controllers and I have been trying to replace the firmware on a Sonof switch which is based on a ESP8266. I have connected up a USB to serial adapter and have manged to firstly power the Sonof up and then successfully upload a sketch from the Arduino IDE. The trouble is whilst it successfully appears to upload (I was uploading Blink) it doesn't appear to work. I thought I may have got the TX/RX connections the wrong way around but it doesn't appear to be possible to do this and still get the sketch to upload.
I may well have bricked the switch now and so have ordered 2 more - don't want to brick them too.
Does anyone have any advice as to what I may be doing wrong?
Thanks
D
