I have a system with (5) Anchors, (4) tags and a Gateway running an MQTT server on a RPi 3B. At times, everything works properly and I get accurate position updates reported by the tags. For long periods of time though (days), the tags will only range to 1 or 2 of the nearby anchors. All devices in this system are DWM1001-DEV boards with PANS 2. All anchors are configured as initiators since only one will actually act as an initiator and I don’t care which one. Anchor location coordinates are configured individually and are certainly accurate. The full size of the ranging area is less than 6m x 7m with the anchors around the periphery. Tags are configured in low power mode with BLE enabled, moving update rate at 100ms and the normal rate at 10s. I am inquiring into the tag activity through MQTT messages not updating a valid location, and UART shell mode with direct USB connection. Shell command “la” correctly lists all anchors without issue. Command “les” displays that the tags are only ranging to 1 or 2 of the anchors at a time, so it’s not calculating a position. I am not local at the site where this is malfunctioning and need to prepare some thoughts for troubleshooting.
- Is it okay to have all anchors programmed as initiators (I believe the PANS network assures only one actually “acts” as an initiator)?
- Are there any settings on the anchors that might impact this?
- Are there settings on the tags that might impact this?
