LE Advertising: Immediate Timeout
From: Ethan White <hidden>
Date: 2021-11-01 16:58:32
Hi,
I'm trying to figure out why BLE advertisements are timing out
immediately on my embedded system. This is happening with both the
example-advertisements python script bundled with Bluez and a gatt
server I wrote (in C using Bluez D-Bus API). Both the script and
C-program work as expected on Pop!_OS 21.04.
This is a clip from a btmon log that shows the timeout in relation to
an LE Set Extended Advertising Data command. The full log is included
below. The log was generated with the example-advertisements script.
