I don't think we have an example showing this, but I'll see what I can do.

If you have a working example where you change the size live please send me the source.

I change the adv in

void func(bool radioActive){
  if (!radioActive) {
        // change adv (the func from the origiran question with the data
        // nordic_advertiser_adv_set with data
  }
}

from

ble_radio_notification_init(NRF_APP_PRIORITY_LOW, NRF_RADIO_NOTIFICATION_DISTANCE_800US, func)

Hi.

[quote user="schef"]Is that a known issue that i can't change the packet size live without stopping the advertisement? Do you have any suggestions?[/quote]

I haven't heard anything about a known issue for this.
I'm afraid I don't have any suggestions as of now, but I'll do some research and see if I can find anything.

Could you upload your code where you change the advertising data?

Best regards,
Joakim

I think i know what the problem is.

I have a custom packet with size od 31 bytes and ibeacon packet with size of 30 bytes. On every radio notification i call my nordic_advertiser_adv_set function and change between these two packets. For some reason after starting the advertisement the first packet that is advertised is the size that will stay until the next start. So it seemed to me that 1 byte was lost in my custom packet but when i looked more deeply i saw that when my custom packet was 31 bytes the ibeacon packet had also 31 bytes. I do not remember that i had that issue in SDK 14.2.

Is that a known issue that i can't change the packet size live without stopping the advertisement? Do you have any suggestions?

On connect advertisement stops by SDK so i start it again. This is when i see this misbehaviour. I will give more details tomorow.

Hi.

This sounds strange.

Are you seeing this when connecting your phone to the device, and then restarting the advertisement while connected to the device?

Or are you connecting to the device, then disconnecting before seeing this misbehaviour of the advertisement?
