Beacon only advertising once when interval is set to ~5s

I think it might've been the iOS app. I had a power filter enabled because there are so many low RSSI devices in my residential neighborhood, but after I turned that off, I'm seeing the packet pings every multiples of 5 seconds. I'm assuming my Mac is just not catching every packet from the device because of all the traffic it sees.

I'm running this on a brand new 52833dk (powered by the coin cell) and scanning from the iOS app running on a Mac. For other detected devices, I can see the advertising packets, but for my tests I only ever see a single dot until I power cycle.

Hello Benjamin,

How did you determine it wasn't advertising? I just added the following to the beacon sample:

struct bt_le_adv_param params = BT_LE_ADV_PARAM_INIT(BT_LE_ADV_OPT_USE_IDENTITY, 0x1f38, 0x1f39, NULL);

Right before starting the adverts, which I changed to use &params, and I am verifying adverts that are >=5s apart. I did notice though that if I try to monitor the adverts using the nRF Connect Mobile app (iOS) the main scan results screen does show the 'Test beacon' device as N/A<->N/A. However, if you select that device and look on the following screen you will see that new packets are coming in as expected, just not showing on the main screen probably due to the large interval.

Let me know if you are not able to confirm this.

Thank you,

Jennifer Gibbs
