broadcast data length

Hi yikai chen,

I waws trying to implement a uart to zigbee convertor in which coordinator receives the uart data and broadcast's the data to all router,
to match with uart speed i need to send bulk data to router so is it possible to do it to send an array of data through broadcast with a length of 100 bytes.

Can I send 20 bytes instead of 12 since iam stuck in 12 bytes

no i want to send that much data at a time to ZC through ZR I am using afdatareq for that purpose. I am able to send an array with an length of 12 bytes at a time over the air . But the array with more than 12 byte of length is not getting sended over the air.

zclZigbeeConvertor_DstAddr.addrMode = (afAddrMode_t)Addr16Bit;
zclZigbeeConvertor_DstAddr.endPoint = ZIGBEE_RS232_RS485_CONVERTOR_ENDPOINT;
zclZigbeeConvertor_DstAddr.addr.shortAddr = 0x0000;

BytesAvailable = 12;
for(i=0;i<BytesAvailable;i++)
{
*(DataToSend+i) = UartDataFifoBuff[ReadIndexFromFIFO++];
}
AF_DataRequest( &zclZigbeeConvertor_DstAddr, afFindEndPointDesc( ZIGBEE_RS232_RS485_CONVERTOR_ENDPOINT ), \
ZCL_CLUSTER_ID_PI_GENERIC_TUNNEL, BytesAvailable, DataToSend, &transSeq, AF_TX_OPTIONS_NONE, AF_DEFAULT_RADIUS);


The Above code works perfectly but when i transmit it with BytesAvailable = 13;

data is not getting transmitted.

Do you check return code of AF_DataRequest when you send 13 bytes?

No till now not i will check it and reply u back

Hi,

I checked the ret it is 0x00 which means success.

but the code is getting into fault isr after some while .
This happens if i send with byte length of 13 bytes but if I send with 12 bytes no such problem will happening and data is getting send also.

I have no problem to send 72 bytes with AF_DataRequest in my application. What example is your application based on?

sample doorlock controller my zstack version is zstack home 1.2.2a.44539

If you disable UART and test again, do it work?

Hi yikai chen,
The problem is solved actually i was using a pointer and storing 100 data's by incrementing the pointer that i think so cased some memory problem, when i tried with an array of fixed size like 100 the problem rectified

Thank's for helping

You are welcome and it's good to know you solve this problem.
