softdevicee s120 rssi problem

[Peter]

Hi everyone

now i used softdevice s120 scan and connect two s110 device and i used sd_ble_gap_rssi_start() when connect event , then get the rssi in BLE_GAP_EVT_RSSI_CHANGED because i connect two s110 device so i get two rssi value but how can i know which rssi value is first device and which is second device?

thanks

Hi Peter,

This is a GAP type event (ble_gap_evt_rssi_changed_t), so the connection handle should be available in the evt->gap_evt.conn_handle struct. The connection handle should correspond to the connection handle you got in the initial CONNECTED event.

Is this not the case for you?

Hi Myhre thanks for your reply . now i used rssi = p_ble_evt->evt.gap_evt.params.rssi_changed.rssi; to get two connected device rssi value in BLE_GAP_EVT_RSSI_CHANGED CASE and it return two rssi value for me ,but i don't know the rssi is first device's or second device's,i want to do is device[0] = rssi[0] ,device[1] = rssi[1] ,how can i doing that
thanks

When you first connect to your two devices, you will get assigned connection handles in the BLE_GAP_EVT_CONNECTED events. These connection handles will appear in other events at a later point to show you what device the event belongs to. When you receive an RSSI_CHANGED event, you have to look up the conn_handle field as mentioned above, then use that to decide which entry in the table to use.
