Hi Dialog,
I am using DA14850 PRO mother board and wlcsp DA14850 daughter board.
I have flashed DSPS host and device example program as default (without modification) in two devices and connected in two PC's.
and used TERA TERM terminal software on PC with baud rate of 115200.
The transmission is happening but it is always giving some unknown values .
Please help me to guess what will be the issue?

Hi RatheeshT,
I suppose that you have the proper connections in order for the HW flow control to operate, check that, and also you need to set the HW flow control at your terminal as well in order to get valid data on the other side of the link.

Hi,
OK ,
I don't have UART cable with hardware flow control (I have 3-wire UART with RX-pin, TX-pin, GND). i.e. why i done the below modification in file "user_periph_setup.h" on both SPS_HOST &SPS_DEVICE projects.
#undef CFG_UART_HW_FLOW_CTRL
After doing that also,it will give the same result.
Whether it will work without hardware flow control or not?
Please provide your ideas to solve this?
Hi RatheeshT,
You can't operate the DSPS without flow control, the wake up of the device is based on the flow control singnal, there is no way to operate DSPS with sleep without the flow control signals.
Thanks MT_dialog
Hi RatheeshT,
Something i forgot to mention, the DSPS partially supports sw flow control if that suits you, but there will be missing data if you use extended sleep mode, although sw flow control is supported in no sleep mode.
Thanks MT_dialog
