Returns event flags set by the previous Bluetooth LE UART transaction
Device (from impOSTM 38)
Integer — the UART transaction event flags bitfield
This method allows you to monitor the UART over which an imp004m is communicating with its on-board Bluetooth LE module.
The integer returned by the method is a combination of values: each UART event flag represents a single bit in the returned value. At the moment, only two possible values will be returned by bluetooth.uartflags(): 0 or 32. The latter indicates an overrun error, which is remedied by closing the Bluetooth session (with bluetooth.close()) and then establishing a new session by calling bluetooth.open() once again.
Because of the need to establish a new Bluetooth session, bluetooth.uartflags() does not clear the event flag record when it is called.
|Event Flag Constant||Value||Description|
|OK||0||Communication was successful|
|OVERRUN_ERROR||32||An over-run error occurred, ie. the receive buffer was full when another character arrived|
The values assigned to the constants may change in a future impOS™ release.
