Change advertisement manuf_specific_data once a second

[buslik]

Currently I am set timeout to one second and then on BLE_GAP_EVT_TIMEOUT:

• modify data
• advertising_init();
• advertising_start();

Are there more correct ways to solve this task?

My main concern that ble_advdata_set is not thread safe and if I will modify data and call ble_advdata_set once a second I can send some corrupted packets.

Agree with @John DeWitt here. As long as you change the content when the radio is not in active mode, you will be fine. You could use the radio notification functionality in the softdevice to get notification on when there will be a radio event. This will give you indications on whether or not it would be safe to write.

Dear Asbjørn could you please provide a link to relevant SDK documentation? The BLE_GAP_EVT_TIMEOUT is the only thing I have found so far.
