ble_radio_notification_evt_handler_t timeslot API and softdevice

[johnofleek]

I am using the timeslot API and softdevice to advertise two separate types of message. This works well. But I have also used ble_radio_notification_evt_handler_t in an attempt to change the payload of the softdevice advertisement.

Unfortunately through experimentation I have found that ble_radio_notification_evt_handler_t is called on any radio activity. There doesn't appear to be a context.

Any ideas how to run code before or after (just) the softdevice advertises?

I'm using S130 V11 nrf51

Many thanks in advance

The easiest way to change the advertising data between two advertising events, is to use app_timer/the RTC to run with the same timeout interval as the advertising interval. Since we know that the advertiser will advertise at a given interval, having app_timer/the RTC to update the advertising data with the same interval will make the advertising data change for each advertising event.

can you explain in a bit more detail why the radio notification doesnt work for you?

I have not personally used it, but I thought there were settings to be notified in advance of the transmission.

Are you just advertising e.g. is this just a beacon?

BTW. Are you aware that virtually no receiver , especially in a phone, gets data every advertising transmission.

In my experience, phone apps often only get notified of about a third of the actual transmissions
