JN5169 transmit data

LUIPS — Mon, 31 Oct 2022 03:11:25 GMT

Hi All:

i am learning to use JN5169 in IEEE 802.15.4 to develop a project.

My project is based on JN-AN-1174. I have already realized the data transmission from EndDevice to Coordinator,but now i am failed to transmit data form Coordinator to EndDevice.Although the template offer the function of data transmission,it doesn't tell me how and where to call the function.

so i need you help to tell me how to correctly realize the data transmission between EndDevice and Coordinator

Thanks.

Hello,

If you already have a transmission from ED to Coordinator, it should be added in a very similar way from Coordinator to ED. Are you having some problem while calling the function?

Also, we highly recommend moving to the JN5189 Wireless MCU for Zigbee® and Thread, as is our focus part for ZigBee/Thread. It is supported by our MCUXpresso IDE and MCUXpresso SDK. There are several SDK examples, like driver examples (GPIO, UART, SPI, I2C), RTOS examples, and Wireless examples (ZigBee and Thread).

Regards,

Ricardo

Thanks for your reply,I've write the transmission function like this:

PRIVATE void vTXDataPacket( uint8 u8Len, uint16 u16DestAdr)
{
MAC_McpsReqRsp_s sMcpsReqRsp;
MAC_McpsSyncCfm_s sMcpsSyncCfm;
uint8 *pu8Payload, i = 0;

/* Create frame transmission request */
sMcpsReqRsp.u8Type = MAC_MCPS_REQ_DATA;
sMcpsReqRsp.u8ParamLength = sizeof(MAC_McpsReqData_s);
/* Set handle so we can match confirmation to request */
sMcpsReqRsp.uParam.sReqData.u8Handle = 1;
/* Use short address for source */
sMcpsReqRsp.uParam.sReqData.sFrame.sSrcAddr.u8AddrMode = 2;
sMcpsReqRsp.uParam.sReqData.sFrame.sSrcAddr.u16PanId = PAN_ID;
sMcpsReqRsp.uParam.sReqData.sFrame.sSrcAddr.uAddr.u16Short = COORDINATOR_ADR;
/* Use short address for destination */
sMcpsReqRsp.uParam.sReqData.sFrame.sDstAddr.u8AddrMode = 2;
sMcpsReqRsp.uParam.sReqData.sFrame.sDstAddr.u16PanId = PAN_ID;
sMcpsReqRsp.uParam.sReqData.sFrame.sDstAddr.uAddr.u16Short = u16DestAdr;
/* Frame requires ack but not security, indirect transmit or GTS */
sMcpsReqRsp.uParam.sReqData.sFrame.u8TxOptions = MAC_TX_OPTION_ACK;

pu8Payload = sMcpsReqRsp.uParam.sReqData.sFrame.au8Sdu;

pu8Payload[0] = sCoordinatorData.u8TxPacketSeqNb++;

for (i = 1; i < (u8Len + 1); i++)
{
//pu8Payload[i] = *pu8Data++;
pu8Payload[i] = 0x00;
}

/* Set frame length */
sMcpsReqRsp.uParam.sReqData.sFrame.u8SduLength = i;

/* Request transmit */
vAppApiMcpsRequest(&sMcpsReqRsp, &sMcpsSyncCfm);
vPutStrs((uint8*)"Request transmit\n");
}

Now,i am confused with where to call the function, vProcessIncomingMlme(MAC_MlmeDcfmInd_s *psMlmeInd),or PRIVATE void vProcessIncomingMcps(MAC_McpsDcfmInd_s *psMcpsInd).

I've tried to print whether the transmission is successful on the serial port.When i transmit the data from ED to Coordinator ,it shows the "Data transmission successful",but when i tried to transmit data from Coordinator ,it always shows "Data transmission failed".

PRIVATE void vHandleMcpsDataDcfm(MAC_McpsDcfmInd_s *psMcpsInd)
{

if (psMcpsInd->uParam.sDcfmData.u8Status == MAC_ENUM_SUCCESS)
{
vPutStrs((uint8*)"Data transmission successful \n");
}
else
{
vPutStrs((uint8*)"Data transmission failed\n");
}
}

Hello,

You can refer to IEEE 802.15.4 Stack User Guide (section 4.2 and 4.3) to check how a typical set-up and operation is used for these nodes.

And also, you can refer to the Application Note 802.15.4 Home Sensor Demonstration for JN516x (JN-AN-1180).

Ricardo
