Checked the DWM222 Modem manually AT+CMGF? and found that it was in PDU mode. I used smstools before. I think the current implementation of ATLib is using Text mode. After switching to Text Mode via minicom. I could send SMS.

Hi

Thank you for reporting this, I appreciate feedback that can make this library better! I'll look into it and see what I can do. You shouldn't need to use minicom, did you try SetSmsMessageFormatAsync(...) to set the mode?

sorry for not updating this issue. yes i already found that call and it worked. maybe just update the minimal example from README.md. I started with that but the modem was in PDU mode from previous usage.
