Setting up a modem using uart2 (BT) AG35

Hello, please tell me, I have a car module with an AG35 modem. There is no main uart1 on the board, but there is uart2 (BT). Is it possible to configure the sleep mode of the AG35 modem using uart2?
Please help.
And how can this be done?

Hi there,

Entering sleep requires a series of actions, basically the idea is to release all of wakelocks in the system when sleep mode is enabled on AG35.
Can’t dive into the detail, cause it all depends on the “car module” as you mentioned.
