ishgum We do something similar in one of our products without any issues. In fact if you look at

ble_advertising.h

in the SDK you will see it implements something called fast and slow advertising is changes the advertising interval.

Hello,

I do not see any issues with stopping and starting the advertising again as you describe. In fact, at least one of the examples in the SDK (the eddystone beacon) does this. You can use the softdevice call sd_ble_gap_adv_stop() to stop the advertisement. Just check the return of this function call. If it returns BLE_ERROR_INVALID_ADV_HANDLE, it is called with an invalid handle. If it returns NRF_SUCCESS, it has stopped the advertising, and you can configure the advertisement with the updated advertising interval. If it returns NRF_ERROR_INVALID_STATE, it means that the device is not advertising (it has already been stopped), and you can ignore this return, and configure the advertising interval.

Best regards,

Edvin
