Message Buffers API wrapped in a mutex for multiple producers?

Posted by hassan789 on December 29, 2017

Hi, Per you documentation here: https://www.freertos.org/xMessageBufferSend.html

I can call wrap the xMessageBufferSend() in critical section, with a block time of 0 for use with multiple producer. Instead of this, can I simply wrap in a recursive mutex, and still keep a non-0 block time?

I asked a similar question awhile ago (for StreamBuffers, but MessgeBuffers are really just StreamBuffers with a bit of additional logic to handle Messages), and was told that with a mutex, as long as only one task can end up blocking on the queue at a time, things will be fine.
