为什么一段时间后Android Wear蓝牙会断开连接-btm_sec_disconnected？

Question

I am developing an android app for android wear Android Wear 4.4W. I'm debugging the app directly via usb in the smartwatch (that's how I want it - no companion app on the phone). The app receives bluetooth messages every 10ms. After 10-20s, this error is thrown -

01-01 21:10:22.683 E/bt-btm  (  826): btm_sec_disconnected - Clearing Pending flag
01-01 21:10:22.686 W/bt-btif (  826): invalid rfc slot id: 4

I'm basically using this code- How to receive serial data using android bluetooth

I tried sending "keep alive" messages as mentioned here- Application using bluetooth SPP profile not working after update from Android 4.2 to Android 4.3 , but this does not work either.

Are there any mistakes that I'm making or any workarounds to this problem?

Ok, found the answer. The external bluetooth module kept resetting itself because of some circuit issues. The reset caused the connection to be lost momentarily.
