USART RTS vs CTS

[Nick102]

Hi,

I would like to connect my Sequans GM02s iot module to my Stm32L4 mcu via uart. Would the RTS Signal from the iot module connect to the CTS signal from STM32L4 or vice versa?

If your IoT module actually works with RTS/CTS, they would have to be connected crosswise, i.e. RTS-CTS in each case.

You can also take a look at the NB-IoT module from STMicroelectronics, which you can find under ST87M01.

Good luck!
