The edit you made should really be posted as a new question. If you are seing the bit toggled on MCP, then it is just an UART message you fail to print when you receive the data. Have a look at BLE_GATTS_EVT_WRITE in on_ble_evt or similar and see what function is triggered. Then put a printf there with the data you want (e.g in p_evt_write->data)

Hi Mohib

In order to port any development kit example to the evaluation kit, look at the porting guide on this thread.

To make the UART work on the PCA10001 evaluation kit through USB, make sure you have hardware flow control (HWFC) enabled.

Thank u very much for the link, but my point is that i am unable to send my own data from peri to central. their is no code of multilink cenral example for pca10001 board . There is code for nrf6310, and when i make changes to work it for pca10001 it does not show any output on hyperterminal whereas i am getting some output by burning the hex of code for pca10001 but unfortunately i dont have its main.c file where i can make changes to send my own data and so i am left with code for nrf6310 only. can i make it work for pca10001 ?

Hi Mohib

I see from you link that you are using nRF51 SDK 6.0.0. You can find source code for all SDKs in developer.nordicsemi.com. You should find the multilink cenral example under the \Nordic\nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s120\experimental
ble_app_multilink_central in SDK 6.0.0

Hello, I am experimenting this link devzone.nordicsemi.com/.../a00064.html. The code of central is for nrf6310. When i changed code to make it work, for pca10001 board , it does not display anything on hyper terminal . However when i burn this hex file www.dropbox.com/.../ble_app_multilink_central.hex , it worked as intended displaying data being received on hyper terminal but unfortunately we dont have its main.c file so that we can transmit our own data. Can i get the code for this hex or make nrf6310 central code workable for pca10001 somehow ?

Hi Mohib

If you have enabled UART debugging on the central by defining the ENABLE_DEBUG_LOG_SUPPORT constant, you should see the peer address when the central connects to the peripheral. It is stored in p_event->event_param.p_gap_param->params.connected.peer_addr. It is printed out in the device_manager_event_handler (main.c file) when the DM_EVT_CONNECTION event is received on the central device.

I have also managed to print this out on Keil RTT debug, if that is of any interest.

I have tested this with SDK 8.1 and softdevice S110 8.0.0 and S120 2.0.0

You will find the address on the central when examening the: p_ble_evt->evt.gap_evt.params.adv_report.peer_addr / p_ble_evt->evt.gap_evt.params.connected.peer_addr <-- Just look for peer_addr Here you can look at the deive that sendt the events address.

If you do not need any receit on the device triggering the btn I would simply go for sending the button press in the advertisement package

i am using multilink_peripheral and multilink_central projects , hyper terminal shows "Advertising notification" on hyper terminal when central is connected ,but not the device id...Also plz ans the 2nd art of question

You could do this without even being connected. Set up the peripheral to start advertising on button press and let the central scan continuously.

Or, set them up to connect each other, let the central request notifications. When you press the button (while connected), this should trigger a notification transmission, and the central will automatically read this data. That's the outline at least
