Re: [bluetooth-dev] Problem of Data Loss of Open BT stack
I might have a different problem when the data loss occured in the UART
HCI level. I suspect that any Bluetooth layer is not supposed to be 100%
UDP protocol is not 100% reliable as well, and it is the application that
has to provide necessary reliability. I know that the TCP protocol is
Unfortunately, one kind of the lowest Bluetooth transport layers, namely
UART HCI, is poorly protected from de-synchronization of frame boundaries.
Receiving 5,700 characters per second seems to be a burden for our
embedded processor and/or serial driver.
Does anybody know if the cli(); instructions seen in the OpenBT code can
prevent the serial driver from handling interrupts? Thank you,
