Hi Hung

I will try the four correct UART pin recently.

And I have bought one Kit and wait it now.

Well, our intend was not to force user to buy our DK or Dongle. But since it's pretty cheap now (only $39), it worth the investment especially you get a programmer for free (if you buy the DK).

To use the sniffer with your own board, you just need to match your UART pins with what we used on our Development board. You don't need a Segger chip to make it work. Just find a way to interface the correct UART pins with your PC. Which are:

P0.08 RTS

P0.09 TXD

P0.10 CTS

P0.11 RXD

Haha..

Thanks for your relpy.

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.

You do need the sdk(source code) to recompile. If you don't have the sdk then you can't do that. If you can you should download the SDK. I'm sure the sniffer app is in there.

Hi AmbystomaLabs

Where can I adjust PIN_NUMBER whitout source code?

nrf sniffer only give .hex file .

And then just run "ble-sniffer_win_1.0.1_1111_Sniffer.exe".

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
 };
