thread_cli_ftd_uart_pca10100 example: move UART port to different pins

[rcerati]

I want to move the uart communication port from default pins to

#define RX_PIN_NUMBER 33
#define TX_PIN_NUMBER 34
#define CTS_PIN_NUMBER 35
#define RTS_PIN_NUMBER 36

I changed the defines in pca10100.h

uart_pca10100 example works fine.

thread_cli_ftd_uart_pca10100 example doesn't change as if pca10100.h had old settings

#define RX_PIN_NUMBER 8
#define TX_PIN_NUMBER 6
#define CTS_PIN_NUMBER 7
#define RTS_PIN_NUMBER 5

Probably thread_cli_ftd_uart_pca10100 doesn't use pca10100.h, is it ?

How can I set a different pins set for UART?

Best Regards

Hi Roberto,

I tried with my nRF52840DK and experienced the same issue as your description. Furthermore, I found the original pins still work even I changed them on sdk_config.h. After checking the code, I found the uart setting for thread CLI might be "hardcoded" under this otCliUartInit function. The nRF52 SDK uses a prebuilt library from the OpenThread project. You can refer to this ticked to change the pins. Thread SDK hardcodes UART pins - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

Best regards,

Hi Roberto,

I found another better solution. If you switch to NCS for your development, this will become much easier. For the NCS openthread CLI sample. You only need to change ncs\nrf\samples\openthread\cli\boards\nrf52833dk_nrf52833.overlay to the following settings:

&uart0 {
	status = "okay";
	rx-pin = <33>;
	tx-pin = <34>;
	cts-pin = <35>;
	rts-pin = <36>;
	hw-flow-control;
};

&uart1 {
	status = "disabled";
	current-speed = <115200>;
	rx-pin = <33>;
	tx-pin = <34>;
};

Then it should work as expected, I have verified on my nRF52840DK, it works well. Since the development on nRF52 SDK will stop, and NCS will become the next generation development platform, so I strongly suggest you move to NCS now.

Best regards,

Charlie

I have a different file tree

I'he found nrf52833dk_nrf52833.overlay under

ncs\zephyr\tests\drivers\counter\counter_basic_api\boards

I cannot use  nRF Connect for Desktop app, because I have the following error

Unable to download latest app info: Unable to download apps list: Unable to download https://raw.githubusercontent.com/NordicSemiconductor/pc-nrfconnect-launcher/master/apps.json: net::ERR_NAME_NOT_RESOLVED. If you are using a proxy server, you may need to configure it as described on https://github.com/NordicSemiconductor/pc-nrfconnect-launcher

so I followed instruction for "Installing the nRF Connect SDK manually"

That is not the correct sample. Are you using NCS1.4.0?

How can I check the version from command line ?
