BLE_APP_BEACON DON'T ADVERTISE REGULARLY WHEN NON_CONNECTABLE_ADV_INTERVAL IS 5000

[FatihAlparslan]

Hello Nordic Team
I want to use the ble_app_beacon example found in SDK 15.3 on NRF52810 when NON_CONNECTABLE_ADV_INTERVAL is MSEC_TO_UNITS (5000, UNIT_0_625_MS). The program runs successfully when NON_CONNECTABLE_ADV_INTERVAL is MSEC_TO_UNITS (1000, UNIT_0_625_MS), but when the interval is 5s, sometimes it sends data at irregular intervals. Please help me.
Best regards

Hi,

How do you see that the interval is irregular? Do you have a sniffer trace that shows this?

[FatihAlparslan]

yes, I use raspberry pi for scanning ble beacon advertisement and I print a timestamp when raspberry pi catches a  beacon advertisement.

Can you share the log? There will always be some missed advertisement packets, and I would think that is what you are seeing. You could verify the advertising interval from the nRF by for instance using radio notification to toggle a GPIO and check with a logic analyzer.
