Resolved: controller won’t stay in sniff mode


I’m using the bluez stack on linux and need to put a slave controller into sniff mode. I am able to initiate sniff mode by issuing the command with hcitool: hcitool -i hci0 cmd 0x02 0x0003 0x00 0x01 0x12 0x00 0x12 0x00 0x01 0x00 0x01 0x00. The problem is that the slave always issues an exit sniff mode command immediately after I send any data on this socket. Can anyone tell me why this is happening and how I can stop the controller from exiting sniff mode arbitrarily?


This ended up being an issue with the default params for the linux bluetooth driver.

If you have better answer, please add a comment about this, thank you!
