BLE Switching between beacon and UART

You might want to take a look at this thread - and the linked threads - about switching between Connectable & Non-connectable advertising:

https://devzone.nordicsemi.com/f/nordic-q-a/47391/sdk-15-3-0-restart-non-connectable-advertising-after-timeout

Note that most of the SDK 15.3.0 examples use the Advertising Module - and this does not support Non-connectable advertising:

So, as Simonr says, you have to do it "manually" with the SoftDevice sd_... calls.

You need to stop advertisements by calling sd_ble_gap_adv_stop, change the advertisement data with sd_ble_gap_adv_data_set, and finally restart advertisements with sd_ble_gap_adv_start. See the ble_app_beacon example for how to set up the advertisement data to the non-connectable mode and for example the ble_app_uart example to set up connectable mode.

Thank you Simon,i tried ... can you give me a simple example that explain the steps how to transform from mode beacon to connected mode without any problem ? , What is the function should be stopped ? What is the function should be activated?

I am struggling to understand what exactly you want. Do you want to switch between UART and Beacon advertising without resetting? In that case, take a look at the ble_app_uart example, and try modifying it to act as a beacon instead of a connectable Bluetooth peripheral.

If you want to change between these two peripherals using a button, that shouldn't be so hard implementing into the ble_app_uart example either.

If you want to set the reset button as another button on your DK, that is not possible.

Best regards,

Simon
