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.

We have data in our advertising packet that needs to be updated once every 10 seconds and another set that updates once per minute. I use ble_advdata_set without stopping advertising and have not observed any issues with data corruption. I can't say I know ble_advdata_set is completely safe, but so far I see no data to say it isn't.

Thank you John, sounds promising. I have also tried like this but I am still concerned.
