how sd_ble_gap_rssi_get API works?

[Swetika]

Hi,

I want to know how sd_ble_gap_rssi_get API works? Is it send any BLE packets over radio to get RSSI whenever application calls this function. What are the sets of events happens when this api is called and is any of these events blocks CPU execution.

Thanks

Hi Swetika, like specified here, you need an established connection to use this function.

Hi,

This link explains sd_ble_gap_rssi_start. My question is for sd_ble_gap_rssi_get.

The documentation covers this very well. It just returns the latest rssi value which was stored.You have to have called sd_ble_gap_rssi_start() first to begin the collection before it will return anything. It does nothing, sends nothing and blocks nothing, just returns the last collected value.
