I am using a "Sigfox AT Slave" example project. When I type the AT command to get the Sigfox ID or PAC I get an "OK" message as if the command worked, but the ID or PAC do not appear.

I would like to create a script by arduino IDE that allows me to communicate in Sigfox. I own an STM32WL55. I haven't found any library on the internet that allows me to do this communication. Is there any documentation explaining how to program this...
