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.

Thank you very much Sara. I have tried something like that before (but likely not quite rightly coded). This failed to switch baud rates too unfortunately. I have tried this on 3 out of 4 wifi bees that I have (but just one with you sketch so far) and no luck, that’s how I ended up asking about the firmware.
Did your sketch in a hurry, so will have another go at it, and on other wifi bees later.
One question though, in the snippet you provided it has “modemBaud = 9600″ that doesn’t compile with the modemBaud being defined earlier in the sketch. I commented that out and put 9600 inthe UART_Def line as

<span data-olk-copy-source=”MessageBody”>modem.gsmModem.sendAT(GF(“+UART_DEF=”), 9600, F(“,8,1,0,0”));</span>

Not sure that’s the right way to handle it. Will report back when I have a bit more time to go through it carefully.

Thanks
