bb_cli connection failed #3

Open kscheff opened 3 years ago

kscheff commented 3 years ago

when running bb_cli with the debug flag -vv on then the device does not connect:

pi@raspberrypi:~ $ bb_cli -vv 24:7D:4D:74:65:0B
INFO:root:Log level set to to 10.
INFO:Device 24:7d:4d:74:65:0b:Connection failed

When connecting the device by hand before running bb_cli then it works:

pi@raspberrypi:~ $ sudo hcitool lecc 24:7D:4D:74:65:0B
Connection handle 64
pi@raspberrypi:~ $ bb_cli -vv 24:7D:4D:74:65:0B 
INFO:root:Log level set to to 10.

Subsequent connections will work without using hcitool again, this survives a reboot. Looks like that the GATT table needs to be in the cache before this runs successfully, see bluetoothctl.

I hope that the new version resolves this problem.
