WISMO228 and CHAP authentication

I’m having problems making the WISMO228 connect to APN that uses CHAP authentication.

The only place I can find anything with CHAP is under bearer configuration ( enabled with WIPBR=2,6,8,1 ). But the module still will not use CHAP authentication.

Am I doing something wrong ? or am I missing something ?

Hi,
The option 8(i.e. WIP_BOPT_PPP_CHAP) of +WIPBR command is used for providing CHAP authentication for the connection between the PC and the wireless CPU (UART bearer). For example CHAP or PAP protocol can be used to create a UART PPP connection between the PC and the Wireless CPU.

Thanks,
