Secondary AT Port can be used for AT command when main modem port is in ppp network mode
There are different sub-models of the above modules. The communication stands may be different. For example, LTE-FDD 5(UL)/10(DL), LTE-TDD 1(UL)/8(DL). And endpoint address may different also, if you encounter problems, try modifying parameters using a custom device mode.
Other 4G Cat.1 module adaptation methods
Confirm whether the 4G module supports USB Fullspeed mode;
Confirm whether the 4G module supports USB PPP dial-up interface;
Confirm that the 4G SIM card is activated and the Internet access is turned on;
Confirm that the necessary signal wires have been connected in accordance with the hardware wiring;
Confirm the module's PPP interface input endpoint (IN) and output endpoint (OUT) addresses, and modify the following options in menuconfig
:
User Defined
board:Plaintext
Component config → ESP-MODEM → Choose Modem Board → User Defined
Plaintext
Component config → ESP-MODEM → USB CDC endpoint address config
→ Modem USB CDC IN endpoint address
→ Modem USB CDC OUT endpoint address
Check outputs log to confirm that the AT
command can be executed;
The basic AT commands supported by different Cat.1 chip platforms are roughly the same, but there may be some special commands that need to be supported by users.
