BLE Scan Results Uplink Data

The device periodically scans for BLE devices and reports the top‑N results. Each entry includes at least the RSSI; other fields are included only if the corresponding wantX flags are enabled in devcfg.blescan.

Key path: devdata.blescan

To request current scan results:

{ "devdata": { "blescan": null } }

`lastscan`

Array of detected BLE devices from the most recent scan cycle. The array is empty if no devices were found or scanning is disabled.

Configuration variables

Type: array of objects
Sent on: After each scan cycle (periodic or on demand)

Each object may contain the following fields, depending on the devcfg.blescan configuration:

Field	Included when	Description
`mac`	`wantMAC` is `true`	MAC address (12 hex digits)
`rssi`	Always included	Signal strength in dBm
`major`	`wantMM` is `true`	iBeacon major value
`minor`	`wantMM` is `true`	iBeacon minor value
`uuid`	`wantUUID` is `true`	Proximity UUID (32 hex digits)
