About hardware flow control

Kaito

Hi! Now I am going to control the hardware flow and control the UART. For that purpose, we send an RTS signal from the external MPU and the nRF 52832 that received it sends out an RTS signal to the external MPU. Therefore, although it is possible to send the RTS signal from the external MPU. but,it is not able to send the RTS signal from the nRF and receive it as the CTS by the external MPU. Why is that? now i am using the ble_app_uart/pca10040/s132/arm5_no_packs ofsdk14.0.0 and nRF52832.

thank you in advanced!!

    DTR is not used with the nRF5 family you need RTD and CTS. The RTS on your nRF52 should be connected to CTS on your peer device and vice versa.

    1. Can you post a schematic or image of your current setup?
    2. What MPU are you using?
    3. And can you post your code as @Matt suggests? Preferably as text and not an image. I know the code formatting here is bad, but text is still better than an image.
