Reply To: Wifi Bee AT Firmware and Baud Rates

I’ve tried some more witht hat code and no luck. So I decided to confrim the AT firmware and I’m not sure if I did or not. Using a USB to TTL I connected directly to the Wifif Bee and used Putty. I did see some text and a brownout warning on the screen. So I used the TTL for RX and TX and I connected a 3.7V Lipo battery to VCC and GND and also the TTL to GND. No brownout warning, but no response at 115200 or any others that I tried (74880, 57600,9600) using the Putty Terminal.  And various other things like more pass-through sketches to talk directly to Wifi Bee on the mayfly, which I don’t know if they should work or not. Get gibberish responses still, but no matter the speed I don’t find any clear text answers from the Bee. Tried all four Wifi Bees that I have and the same.

Any other hints for what I’m doing wrong?

The  same mayfly boards work just fine with a Sim7080, so I haven’t damaged them in any way.
