[wilkxt]

Hi
I use esp-modem commponents and pppos_client example.
I set esp_modem_set_mode(dce, ESP_MODEM_MODE_CMUX) to set mix data and command mode its works ok. I my send data and sned AT command, esp_modem_send_sms(..) work OK.
But I don't now how get notification of receiving an SMS?

Nobody uses (CMTI) SMS notifications? Checking in the loop whether a new SMS has arrived is a solution, but it is unnecessarily CPU-consuming.

This is the solution at the moment, I send a command to read an SMS every second, and when a new one appears, I can read it.
