BG96 Ready after power up

Hi
We are using the BG96MA with the ST Cellular library. Our hardware does not have the BG96 STATUS pin connected to the microcontroller.

My questions:

  1. After power up, how can the microcontroller know the BG96 has booted and is ready for AT commands other than waiting for a 5 seconds? (Ideally using the ST Cellular library.)
  2. If a delay must be used, what is sufficient, 5s, 13s?

Thank you.
Pieter.

According to the BG96 boot sequence diagram, the AT command can be sent after the UART is activated, generally 4.9s.
