DWM1001 Software API Query


As per the DWM1001 software API guide, there is a TLV command [0x30, 0x00] to get node id (section 5.3.31)
And there is another TLV command [0x3A, 0x00] - dwm_bh_status-get (section 5.4.1) in which two bytes of response is also mentioned as node_id.
I want to know the difference between these node-ids.
Kindly suggest

Thanks & Regards
