Using nrf sniffer without Evaluation Kit

[pikachu]

Hi everyone

I want to use nrf sniffer for debugging.

But I don't have required hardware Evaluation kits in User Guide

Can I combine single nrf 51822 with USB-to-UART as a sniffer?

What should I notice?

Are there limitation on pin number set for TX,RX,CTS,RTS?

Perhaps Nordic will have a different view of this, but the only major difference between the dev boards and a standalone nRF is the segger. As long as you have a segger programmer you can pick up the virtual uart port and should be able to run the sniffer app on any 51822.

And, if you don't have a segger programmer and are using something else, then you should also be able to modify the sniffer code to load a standard uart driver and then can do standard 4 wire comms through gpio.

And you can use any normal gpio. When you add the uart driver there are just a bunch of #defines for the pins and baud rate.

See below:

const app_uart_comm_params_t comm_params =
 {
     RX_PIN_NUMBER,
     TX_PIN_NUMBER,
     RTS_PIN_NUMBER,
     CTS_PIN_NUMBER,
     APP_UART_FLOW_CONTROL_ENABLED,
     false,
     UART_BAUDRATE_BAUDRATE_Baud115200
 };

Sorry, doesn't look like the source code for the sniffer is in the SDK. Or, it's under a different name. Perhaps they use this as a hook to get one to buy the dev boards.
