Hi, I am trying to interface my Quectel ec200u-cn module to nrf52832(custom) board using uart protocol. I have attached a level sifter between nrf52 board and gsm module. I am sending AT command via uart to ec200u but not getting response. what are the cofiguration for command mode?

You need to first make sure that the module starts properly and that manual debugging can send AT commands normally

Hi, module starts properly. I am using main uart. I only used RX , TX and GND pin. is RTS and CTS pins are necessary for uart communication with nrf52832 board?

You need to make sure that your design meets the requirements of both hardware design and UART design
