The meaning of RSSI value of ESB packet.

Hi,

In ESB protocol, the have a RSSI field in nrf_esb_payload_t structure., and I can use this field to get radio receive signal strength.

Does the larger the value, the better the signal?  Ex. if the RSSI values are 50 and 70, which radio signal is better?

If I want to get a error-free RF communication,, what is the minimum RSSI value?

Thank you,

Chianglin
