CC1310: How to redo EasyLink_receiveAsync

Winter Two

The concentrator's example is this:

void TaskFunc()

{

EasyLink_receiveAsync();

while (1) {

if (Valid_Packet_Recv) {

EasyLink_receiveAsync();

}

if (Incalid_Packet_Recv) {

EasyLink_receiveAsync();

}

And now I need to redo a EasyLink_receiveAsync() when a user opration come, what my func is this:

void User_Func()

{

EasyLink_abort();

Semaphore_post(busyMutex);
asyncCmdHndl = EASYLINK_RF_CMD_HANDLE_INVALID;

EasyLink_receiveAsync();

｝

Now I found it can't recv any packet after User_Func()，Is my opration wrong?

Hi TI engineers, Could you tell me the right way to redo EasyLink_receiveAsync().

I can not tell from the code snips you have posted. A few things to note:

- The EasyLink_recieveAsync callback will get called when you about, so you need to make sure that that you take care of the Abort status in the callback.

- The EasyLink functions can not be called from any drivers callback. Where do you call User_Func () from? Is the user operation a key press or UART callback?

- valid_packed_recieved and invalid_packet_recieved should be implemented are semaphores or events (see rfWsnConcentrator example for using semaphores and events).

- Finally take a look at rfEastLinkRx, this uses the EasyLink_recieveAsync() and EasyLink_abort(). This should hopefully show you how to use these API correctly.

If none of these suggestions help then please post you entire code.

TC

- My User_Func() is called by a Event_Handle posted by UART callback. It maybe OK.

- rfEastLinkRx’s sample doesn’t call EasyLink_recieveAsync() after EasyLink_abort(). So i still don’t know what steps should do to Redo EasyLink_recieveAsync()

I commit my code to github, please see my commit 2 on this repository:

Sorry for the delay in response. It is NOT ok to call any driver function from a drivers callback, as the callbacks run in the HWI context. This includes EasyLink_abort() as this call RF driver functions. You must post a semaphore or event and process this in the Task
