LAUNCHXL-CC1312R1: pthread example for switching from Rx to Tx mode for CC1312R1

Part Number: LAUNCHXL-CC1312R1
Other Parts Discussed in Thread: CC1310

Hello,

I am using LAUNCHXL-CC1312R1 for developing firmware. As every sample program in sdk is using pthread programming, I am trying to use Rx and Tx examples together.

My application needs to stay MCU in Rx mode always and after receiving the data, it will switch over in Tx mode to transmit the data and again goes back to Rx mode.

For this, I am trying to use condition variables but after first attempt, my program gets stuck at mutex_lock() ?

Is there any sample program to switch from Rx to Tx? Please let me know if more information is required

Regards,

Omkar

Hi Omkar,

I can recommend you look into the rfEchoTX and RX examples. If your goal is to have two separate tasks for RX and TX then I would suggest using a semaphore synchronization between the two tasks instead of a mutex.

Hi M-W,
I will look into rfEchoTX and RX examples. I had used separate Rx and Tx task for CC1310 with the help of answer provided by PrashanthS in one of the forum and that worked perfectly. So, I was thinking whether same can be done using pthreads.

Hi Omkar,

pthreads and other POSIX APIs are simply wrapping the normal TI-RTOS modules so it should be no problem implementing this.
For example, a task created using pthreads are no different from a task created using the usual TI-RTOS "Task API". To sync the two task, I still recommend using semaphores, you could use either TI-RTOS style or POSIX style semaphores for this.

Hi M-W,
I understood it now very well. I'll stick with TI-RTOS style semaphore as I have already used it before.
Thank you!
