ttyUSB2 port is used for both 3G/4G and AT commands. When we use 3G/4G, ttyUSB2 is locked and we can’t send AT commands to MC7455. Vice versa, when we can send AT command, we can not use 3G/4G.
Is there any solution to use both 3G/4G and AT commands at the same time for port ttyUSB2?
Can anyone help?
Thank you in advance.
