ESP 8266 modules will not work
Posted: Fri Nov 03, 2017 8:35 amI have about 20 of these modules that I use for my Christmas lights displays. I have programmed about 12 and they work fine. I have 8 that I ordered from the same place as the others but will not program. Will not communicate by PuTTY as well. I have sent pictures of these. They have a V3.0 on the bottom and the others do not. All else looks the same. Tried to re-flash the firmware with a failed to connect error. Anyone know what the problem might be?? Thanks
