The DSPS sample can only send data from PC to DSPS app.

I debug the DSPS example(v5.150.2), and can only send from PC to DSPS app, when send from app, the user_ble_push function get called, but seems can not trigger any send from UART TX. I'm using custom board, and my board use P0.4 as TX and P0.5 as RX. If I download and debug the ancs project, it can print message to PC, and the ancs project also use P0.4 as uart tx, so the hardware of my custom board is OK.

It's because the cts pin is

It's because the cts pin is not connected on my board, after connect the cts pin to GND, Tx to PC now get OK.

Hi cgha,

The DSPS project uses extended sleep mode by default, so you should have Hardware Flow Control (RTS/CTS). Can you please make sure that you have this setup in your custom board? Please check the user_periph_setup.h in order to find in which GPIOs the RTS/CTS are exposed. Which configuration do you have in the Serial Monitor setup?

Thanks, PM_Dialog
