Hi,

The BLE address and data is part of the advertising packet, and you can access it when you get the event BLE_GAP_EVT_ADV_REPORT. You can print out the BLE address like below after you get the event. Take a look at the function ble_evt_handler in the ble_app_uart_c example.

NRF_LOG_INFO("Connecting to target %02x%02x%02x%02x%02x%02x",
                     p_adv_report->peer_addr.addr[0],
                     p_adv_report->peer_addr.addr[1],
                     p_adv_report->peer_addr.addr[2],
                     p_adv_report->peer_addr.addr[3],
                     p_adv_report->peer_addr.addr[4],
                     p_adv_report->peer_addr.addr[5]
                     );

You can store the data and address after getting the BLE_GAP_ADV_REPORT event. Do you want to store it in flash?

I guess the most important part is the scan_start function and the BLE_GAP_EVT_ADV_REPORT case in the ble_evt_handler function. can i in the BLE_GAP_ADV_REPORT case store data and adress to the advertise device easy?

Im not even sure that i get the advertise messages from the switch. is there any way to print in the terminal the adress to all nearby advertising devices.

Hi thanks for answering!

I have read that tutorial but still dont get how i store the advertise data in a variable. But i guess i have to go through it again.

Hi,

I suggest you to go through this tutorial. In this tutorial you will set up a NUS server, but I think it will help you to understand how you can set up a simple central that will do what you mentioned above.

To clarify what i want to do:

I want to scan for the switch(PTM215B) and read the advertise report and store the data in a variable. i dont want to connect to the switch. is there a tutorial or something like that for this? In the blinky example there are many functions do i need all if no which funktions do i need?
