CC1310 rfPacketRx接收数据如何避免阻塞

我合并了rfPacketTx和rfPacketRx这两个例程，希望能实现从A模块发送数据包到B模块，B收到后返回给A应答，这样A、B模块要都需要开启收发功能。

TX和 RX分别放到2个任务中，TX先初始化，再初始化RX，但是一旦执行RX任务下的

RF_runCmd(rfHandle, (RF_Op*)&RF_cmdPropRx, RF_PriorityNormal, &callback, IRQ_RX_ENTRY_DONE);后，就阻塞在里面了，

TX任务也被阻塞了，无法发送。

请问要在一个模块上做到RX， TX功能应如何处理？

根据您的描述建议您使用Listen Before Talk例程做发送。

收发例程可以参考Wireless Sensor Network。

• The Wireless Sensor Network (WSN) Node and Concentrator examples illustrate how to create a very basic sensor network consisting of one or many Node device(s) and a Concentrator device. The example shows how to form a one-to-many network where the Nodes send messages to the Concentrator.
• The Node use the Sensor Controller Engine to periodically read the value of the light sensor.
• Whenever the sensor value change, the main controller wakes up and sends a packet with the value to the Concentrator.
• The Concentrator is always waiting for incoming packet.
• Once a packet is received, the Concentrator sends an acknowledgement packet in return and displays the data on an LCD (if the kit has one)

希望对您有所帮助，谢谢！

Hi, Susan Yang:

Listen Before Talk里是以TX为例，加入了pNextOp和RF_cmdPropCs.csEndTime、RF_cmdCountBranch.counter等，这些参数可理解为等待时间吗？

那么RX也用这样类似的方法，就可以避免阻塞了吗？

半双工通信，通过握手协议切换收发状态。

利用例程easylink：使用中断函数非阻塞

if (EasyLink_transmit(&currentRadioOperation.easyLinkTxPacket) != EasyLink_Status_Success)
{
System_abort("EasyLink_transmit failed");
}
}
/* Enter RX */
if (EasyLink_receiveAsync(rxDoneCallback, 0) != EasyLink_Status_Success)
{
System_abort("EasyLink_receiveAsync failed");
}

Eggsy Pang：

嗯，已使用easylink，实现非阻塞方式收发。
