Part Number: CC1354P10

Tool/software:

Hello, i use "ns_br_LP_EM_CC1354P10_1_tirtos7_ticlang" example and i write own library to communicate with it by uart spinel. Can I read rssi to members of my net? I can do it on coap device. There is dedicated rssi endpoint. But what with rssi from border router to coap devices?
