LAUNCHXL-CC1310: Trying to change the channel frequency from 902MHz to 906Mhz in the TIDA-01547 / TIDA-010003 reference designs

Wonsoo Kim The application note is for supported band in TI 15.4 Stack but Robert would like to change this to 906MHz. Can you elaborate how to do this?

Wonsoo Kim Get your point. However, if we intend to use 297-351MHz like the discussions in e2e.ti.com/.../788157 , what should we modify? Or we cannot support it?

Get it and Thank you.

Hi YK,

I found similar settings in mac_settings.c. Would it be better to change these or the mac_user_config_cc13x0_subg_cop.h.

Regards

Hi Wonsoo,

Thank you for the app note. I understand how to change the sub-freq for the TIDA-010003 end node, but I am confused about how to change the root node using the MAC_FH_SET_REQ. In the TIDA-01547 root example I found the following in 6lowpan/host_api/mt_mac.c @ line 178


uint8_t macCreateFHSetReq(Mt_mpb_t *pMpb, MtMac_fhSetReq_t *msg)
{
pMpb->cmd0 =(MTRPC_CMD_SREQ|MTRPC_SYS_MAC);
pMpb->cmd1 =MT_MAC_FH_SET_REQ;
pMpb->length=sizeof(msg->attrId)+msg->attrSize;

pMpb->pData=calloc(1, (sizeof(msg->attrId)+msg->attrSize));

if(pMpb->pData==NULL)
return (ApiMac_status_noResources);

memcpy((uint8_t *)pMpb->pData, (uint8_t *)msg, sizeof(msg->attrId));
memcpy((uint8_t *)(pMpb->pData)+sizeof(msg->attrId), msg->pibValue, msg->attrSize);

return (ApiMac_status_success);

Can I use this function or similar to send the appropriate MAC_FH_SET_REQ? Sorry for the obvious questions, I'm a hardware person and my programing is not that great.


Best Regards,
Robert

Thank you Wonsoo!
