CC2538: PANID and extendedPANID manipulation

Xian Wang42

Part Number: CC2538

I found that I comment out the ZMacGetReq( ZMacExtAddr, zgExtendedPANID ) in zgInit( void ) and then try to assign my own EPID in zgExtendedPANID, but it does not work. The beacon still shows the EPID as the MAC address. I just assigned the zgExtendedPANID as below,

//ZMacGetReq( ZMacExtAddr, zgExtendedPANID );
zgExtendedPANID[0]=0x5B;
zgExtendedPANID[1]=0x2C;
zgExtendedPANID[2]=0x2C;
zgExtendedPANID[3]=0xFA;
zgExtendedPANID[4]=0x57;
zgExtendedPANID[5]=0x75;
zgExtendedPANID[6]=0x5D;
zgExtendedPANID[7]=0x12;

Is there something wrong with my code?

Xian,

Yes, you're not actually setting the actual extended address from your code.

I'd recommend before the ZMacGetReq() item, you can use the 'ZMacSetReq()' API and set the ZMacExtAddr to your desired address.

Best,
Sean

Dear Sean,
Thank you for your help. I think what you recommend is to set another MAC address for the controller, but what I want is to set one EPID that is not same as the controller's MAC address.

Ah I understand now. By default, we do set the extended PAN Id as our MAC address.

Try also setting "zgApsUseExtendedPANID" as what you want your network identifier to be.

Thank you sir, it works well, now the beacon shows different EPID from the device MAC.
