CC1110 read RSSI value?

Alex Trie

Hello professors,

I am using CC1110 mini developent kit, I would like to read RSSI of a received message. I read the RSSI register value, it is nearly -111 or -98 and that values do not change when I increase the distance between 2 CC1110 kits.

I think that this value is not true and I do not know where is the correct value?

    Hi

    If using recommended settings from SmartRF Studio, APPEND_STATUS = 1, and the RSSI of the received packet is appended to the payload and can be read from the RFD register the same way as the payload is read from there. If you are using DMA to read data from the RFD register, please take a look at DN107 (http://www.ti.com/lit/swra164) to see how the DMA should be configured.
