Problem in SIM7600CE-T
shrestha_hk 2019-11-06 00:56:01 6935 Views7 Replies Hello All,
I had bought the DFROBOT sim7600ce module from mouser. I have connected the module with 12V battery, Main antenna , aux antenna and put the sim card. But the Net light is flashing continuously in every 200-300 mSec. While I had connected the jumper Rx->D8 and Tx->D7 and tried to test command it doesn't respond anything.
Please guide us to resolve the problem.

The problem has been solved!
Dear all, if you are facing communication problem with SIM700CE-T LTE shield, please be sure you are communicating with 115200 bps. It doesn't supports the auto baud.
Dear @nana.wang, We are monitoring the river data for early warning and water level monitoring purpose. Due to upgrade of network provider to LTE we are updating the system from 2G to 4G. But due to insufficient library we are facing some problem in beginning. shrestha_hk

I have been using Arduino Uno for AT command testing using Software serial as well as hardware serial. Yes I have used the jumper to connect D0/D1 or D7/D8 for Rx/Tx.
I also used the USB-TTL connector for communication, while I send the AT through serial port it doesn't respond anything(OK is expected) . shrestha_hk
