@Mohib: We provide the SDK without any pre-compiled hex. So if you have hex file in your folder, most likely it was built by you earlier.

developer.nordicsemi.com. You can find the multilink cenral/peripheral example under the \Nordic\nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s120\experimental\in SDK 6.0.0. I am not sure right now which ver i have ,5 or 6 but i think it doesnt matter. I shall try that uart example.

@Mohib: If you can toggle the LED when there is a button press. I see no reason why you can't print out something on UART at the same place where the LED is toggled. If you are not familiar with UART you can try to have a look at UART example, or ble_app_uart example. Which hex file did you mention ? Please give the full path and name to the hex file.

Yes, LED toggles on button press. One another key issue is that i am trying to run ble_App _multilink_peripheral and central of nrf6310 folder with modifications like changing the directive and LED number with respect to 518222ek but it does not show anything on terminal whereas the LED toggles on slave. However , there is 1 more pair of peripheral and central hex in my folder (i dont have its code) that displays data in the terminal when central is connected to PC. Is that again same issue of client_handling.c file ? or Can i somehow get code from that hex ?

@Mohib: I assume that you have the LED turn off and on when you press a button on the slave. If it's the case you should have a look at the on_evt_hvx() in client_handling.c. This is where we update the LED when we receive a notification packet from the slave.

You can try to print out on UART when you receive a call to this function.

@Mohib: could you explain more on " I am getting some data on termial using ble_app_multilink_peripheral and central code but not the value of button" ? Which data have you got ?

i think i may be unable to explain my point to you. in simple, i want to send value of a salve kit button whenever it is toggled, on central. The value highlighted in the pic , i want that on my central and display on terminal. I am getting some data on termial using ble_app_multilink_peripheral and central code but not the value of button

@Mohib: If your plan to use nRF51822 as central, I guess you can go straight to that and try to connect the nRF51 with the Raspberry PI via SPI, UART or I2C.

If you really want to test with the dongle, you can think of using the Master Emulator APIs, instead of using the Master Control Panel. The Master Emulator APIs could be found at C:\Programfiles(x86)\Nordic Semiconductor\Master Emulator.

We have some examples in that folder as well.

m using another 51822 board as central, dongle is just for testing. from central , data is sent to pi

@Mohib: If you simply want to forward a button press on a nRF51822 ek to another embedded board ( in your case the Raspberry PI ? ) would it's be better to use another nRF51822 as a central device (instead of the dongle) and output it to GPIO pin ?
