Timing issues with the pc-ble-driver 'c' library

[Johnnie]

I am trying to bring the pc-ble-driver code up on a single processor ARM based board with Linux build under Yocto control. The boost library version being used is 1.60.

I am having timing issues. It looks like the UartBoost::open code is creating a thread for handling async reads from the serial port and then doing a condition variable check which most of the time times out before the thread has a chance to get started to satisfy the condition.

Is this a known issue?

Also, where can I find the best documentation on the protocol to the rf52 serial device?

Thanks in advance,

Johnnie

Hi,

This might be an issue caused by timeout because the ARM board is using too long to process.

Timeout on read is an error that has a fix in the branch multi_sd, the fix was verified on OS X so no guarantees for Yocto.

The timeout to reach state ACTIVE for async read is 2 seconds.

As for the documentation the BLE serialization section on infocenter should prove helpful.

Best regards,

Øyvind
