> HCI Event: LE Meta Event (0x3e) plen 16 #27 1005.066434Įvent type: Scan response - SCAN_RSP (0x04) > HCI Event: LE Meta Event (0x3e) plen 36 #20 1005.023423Įvent type: Connectable undirected - ADV_IND (0x00) LE Set Scan Parameters (0x08|0x000b) ncmd 1 But if I do a regular (Bluetooth Classic) scan before a LE scan, all the LE scan results RSSI's are the same as the last Bluetooth Classic scan result.įor example, the below LE scan was initiated by running "hcitool lescan" and the output was captured from "btmon" after a classic bluetooth scan was done and the last device reported an RSSI of -74dBm RAW Open: hcitool (privileged) version 2.22 1005.001455 If the device is scanning just after a reboot, all the RSSI byte values are 0x00. However, when running a Bluetooth Low-Energy scan, none of the returned RSSI values look valid.
I'm using the chip in H4 HCI UART mode and interrogating it from Linux, It connects fine and I'm able to run commands on it without any problems. I'm having an issue where the RSSI data for LE scan results coming from my CYW20706 seems to be incorrect.
