Any chance to get support for multiple advertising messages?

[Marius Heil]

Hello,

I really need the ability to switch between different advertising messages. Could you please (please!) add a callback after an advertising message has been sent or allow different advertising messages to be queued? I want e.g. two advertising messages A and B to be sent like this:

A B A B A B

The radio notification handler is called far too often and cannot distinguish between connections, advertising, etc,..... I could use a timer, but this will run completely asynchronous to the Softdevice scheduler. I want to have a clean solution for this problem.

Thanks, Marius

Hi Marius,

I don't think what you request is very common, I haven't seen many applications require that (or simply ok with the scan response).

I can't think of a clean solution for this. What you described of using a timer maybe the closest on what you can do to achieve.

I am also thinking of counting the distance between Active and nActive radio notification signals to measure the size of the packet. And if you have a fixed length of 31 bytes payload for the advertising packet, there is a chance that you can distinguish between a connection event packet (max 36 bytes) and a advertising packet (max 46 bytes). Of course there is a chance that the radio notification be skipped because of 2 radio events are too close. But if that's the case I would hope that the timing can also point out that it's a connection event + advertising event or not.

Re-iterating that the method to establish connections is already available in the github repo mentioned in my answer. However this is limited only to the peripheral role, you still need to use the master role from the Softdevice for connections. Would this address your issue.
