Radio test example - UART pins

[Upright]

Hey there,

We are working with NRF52832 WLSCP package,

We had stated certification process , for BQB testing need to use the Radio test example with UART between EUT to the PC ( using a dongle or SDK)

As my new design does not use all required GPIO, Idon't have direct connection to connect UART pins

1. Is there a way to do the UART over BLE?

2. How to change the pins to fit my accessible GPIO's?

Default GPIO nRF52832	UART nRF52832	Interface MCU UART
P0.05	RTS	CTS	P0.07
P0.06	TXD	RXD	P0.08
P0.07	CTS	RTS	P0.05
P0.08	RXD	TXD	P0.06

actually, the difficulty is how to redefine the pins..... as it is not clear from the example.. 

regard sdk in the website only version 17 is available for download

[JONATHAN LL]

You are using the nrf52832 WLCSP, and you want to use P0.07, P0.08, P0.05 and P0.06 as the UART pins ?

Are you more familiar with the nRF5 SDK or the nRF Connect SDK ?

In the nRF5SDK you can do it in the main file, if you build for the PCA10040 it will be for the 52832.
 

In nRF Connect SDK you have to create a overlay file for the new pins you want to use.

See example in this devzone ticket, 

&uart0 {
compatible = "nordic,nrf-uart";
status = "okay";
current-speed = <115200>;
tx-pin = <6>;
rx-pin = <8>;
/delete-property/ rts-pin;
/delete-property/ cts-pin;
};

Here is a link to zephyr overlay, Devicetree HOWTOs — Zephyr Project Documentation 

Regards,
Jonathan

on top of this regard doing it using segger is there a clear application note , as the ticket is not clear...

RX TX testing is mandatory for regulation purposes... and guidance is required to be provided to the lab.

Simply need clear and simple instructions ....which are working...

[JONATHAN LL]

In the nRF5 SDK v17.1.0 that you presume you have downloaded, you will find the pin number as defined like the picture above. 

You can change the "TX_PIN_NUMBER" and "RX_PIN_NUMBER" to the pins you need to use in your layout. You only need to edit the two instances to P0.06 and P0.08

Regards,
Jonathan

Well this is not good enough as this is Only UART pins,I got inputs that pins are defined in h file

and also need to define ALL the 4 pins required not only rx tx

PCA10040.h i changes as follows, currently still having issues ...

[Upright]

So is there something we are missing here?

[Upright]

Any update?
