WISMO218: Automatic baud rate

AT+IPR=0 is supposed to set the WISMO218 to automatic rate detection.
It doesn’t. Don’t try it.

Anybody know how to restore factory defaults to a 218 without serial comms?
I’ve tried communicating at all supported bauds, no echo or responses.

No flow control was active at the time - AT+IFC=0,0.
Echo was on. A 2-wire serial link is implemented as per Figure 8 of the Customer Design Guidelines Rev002.


I have your problem too.
did you find the solution?

Thanks a lto in advance

Hi Fabio,

Do you remember the FW version running on that module?
Have you tried to connect with default baud 115200 after this pb?
