Clear cached data. Showing old advertisement data

[EdwinFairchild]

I have a device that when given commands via a terminal interface changes its advertisement data. The device does not change anything until the commands are sent.
However Bleak/BlueZ get into a state where it displays stale adv data.
As seen below it starts with adv data eddie upon physical reset
when commands are sent it cycles between newAd and test112345
at some point it starts to show both.
In the second to last log event below I completely power cycle the device and it should just show eddie yet it is showing data that is in fact NOT being transmitted.

Pretty sure it is probably a BlueZ issues since I can power cycle the device and also restart my Bleak application and still shows old data.

Any insight?

When it starts appearing twice, the CID is different (1207 vs 1077) which is why we see both instead of one replacing the other. You could log Bluetooth packets to see if this is really what the device is sending.

I noticed that but this is not the case, think that is an artifact of it jumbling data together , ill try to use a sniffer to see whats actually being transmitted

not sure what i was doing last week, but I cannot seem to reproduce anymore.
