About the multi-channel link problem of sim7600ce [Copy link]

I read in the manual that if the first channel is set to transparent transmission mode, then the second channel can only be in command mode. If the first channel is in transparent transmission, can the second channel still send data to another server through commands? On the contrary, if the first channel is in transparent transmission, and another server sends data to the second channel, will it affect the first channel, or will they affect each other? Because I don't have the actual device on hand, I can't debug it. Can anyone tell me?

Command mode. Transparent mode only supports one socket.

SIM7600CE has only one serial port, and two TCPs share one serial port. If one TCP is transmitting and receiving data in transparent transmission mode, can the second TCP be transmitting and receiving data in non-transparent transmission mode? Yes, will it affect the other TCP?

Didn't I tell you that the command mode is used when there are more than two channels, and the transparent mode only supports one channel. The command mode is not as complicated as you think. The data received in the command mode will contain a fixed header to tell you which server the data is transmitted from and how many bytes it is.

You are talking about the 800 series, right? The 800c series uses command mode for more than two channels, and transparent mode only supports one channel. The sim7600ce manual does not say this. The sim7600 multi-channel connection supports one channel transparent transmission and 5 channels of command.
