Forum Post: Possible performance issue resulting from App having lowest OSAL priority

Hi All,

In the CC2541 MiniDK sample app code, apps have the lowest OSAL priority.  Our app will need to bit-bang over SPI.  I am concerned that OSAL latencies in the sample code framework may negatively impact the reliability of this communication.

QUESTIONS:

1)       Has anyone any experience with this?

2)       Has anyone any experience of defining a higher-priority OSAL task to handle timing-sensitive App activities, and what effect his has on system stability?

Thanks in advance,

MH
