Hello,
I am using the EG915N-EU module connected to the STM32 via the USB interface. After starting the USB port, specifically the USB Modem port, the device sends the following messages:

What do they testify to?
How can I use the EG915N-EU chip to exchange data between the server and the STM32? Is there any documentation describing the data exchanged on the USB Modem port?
