Did you find a solution for that? I am trying to use the camera while doing bluetooth work and am experiencing exactly the same.
Scanning without having started the camera looks like this:
< HCI Command: LE Set Scan Parameters (0x08|0x000b) plen 7
Type: Active (0x01)
Interval: 10.000 msec (0x0010)
Window: 10.000 msec (0x0010)
Own address type: Public (0x00)
Filter policy: Accept all advertisement (0x00)
> HCI Event: Command Complete (0x0e) plen 4
LE Set Scan Parameters (0x08|0x000b) ncmd 1
Status: Success (0x00)
< HCI Command: LE Set Scan Enable (0x08|0x000c) plen 2
Scanning: Enabled (0x01)
Filter duplicates: Enabled (0x01)
> HCI Event: Command Complete (0x0e) plen 4
LE Set Scan Enable (0x08|0x000c) ncmd 1
Status: Success (0x00)`
While scanning when the camera was once active looks like this:
< HCI Command: LE Set Scan Enable (0x08|0x000c) plen 2
Scanning: Disabled (0x00)
Filter duplicates: Disabled (0x00)
< HCI Command: LE Set Scan Parameters (0x08|0x000b) plen 7
Type: Passive (0x00)
Interval: 10.000 msec (0x0010)
Window: 10.000 msec (0x0010)

Can be closed. It works fine with an external bluetooth adapter - so this seems to be a hardware related topic.
Hello
I am having an issue when implementing bluepy while also taking photos using the Raspberry Pi Camera (using the python library picamera) on my Raspberry Pi 3B+. In my code, I first scan and connect to a designated bluetooth device, after which I take a photo. After I take this photo, the Raspberry Pi seems to be no longer able to receive messages/notifications from the previously connected peripheral. In addition, when that program completes and returns, I cannot re-scan for more devices when I restart the program, with this error resulting:
I am then able to eliminate this error by power-cycling the Raspberry Pi. However, then the same issue then arises when I run the program. FYI, I am using python's Threading module to create a daemon that runs BLE in a separate thread while the main thread does other tasks like taking photos.
Any feedback or insight into this problem would be very helpful.
