Problem establishing PPP connection with UBLOX SARA-R510S

Postby robjderr » Mon May 13, 2024 2:28 pm

I'm trying to establish a PPPoS connection to a SARA-R510S-00B module using the esp_modem module but the PPP session is failing. Here's the communication between the CONNECT and NO CARRIER responses. The same code works correctly with the SARA-R412M module.

Code: Select all
