Deployment Preparation Checklists

Configuration

Some things to double-check.

  1. Setting 0 for some Meshtastic settings does not result in a default value
    1. lora.hop_limit of 0 results in a valid setting of 0 rather than the default of 3
    2. Telemetry (device, environment, power) interval setting of 0 in ROUTER mode does not result in a default of 30min but rather auto-scaling with a minimum of 12 hours (see meshtastic/firmware#4466)
  2. Be careful with Meshtastic CLI when trying to add authorized admin public keys (see meshtastic/python#827)
  3. Double check configuration with --export-config​

Packing List

  1. New Meshtastic Device
    1. Firmware, latest alpha build with my_hams changes
  2. Hardware
    1. Ladder, A-frame, 6 or 7 step (1.5–1.7 m height)
  3. Hand Tools
    1. Screwdriver, Phillips, PH0
    2. Screwdriver, Phillips, PH1 or PH2
    3. Screwdriver, Slotted, ≈5mm
    4. Wire cutter
  4. Electrical Tools
    1. Laptop, with Meshtastic CLI and Meshtastic firmware and development environment
    2. RTL-SDR
    3. Powerbank, with USB-A and USB-C PD
    4. 1-2 Meshtastic devices
  5. Cables
    1. Coaxial RF cable, for node to antenna, RG58/LMR200 or similar
      1. Be extra careful of RP-SMA and SMA compatibility - SMA female and RP-SMA male connectors are physically compatible but will air-gap the signal conductor
    2. Coaxial RF cable, for RTL-SDR
    3. USB, Type-C to USB Type-A
    4. USB, Type-C to USB Type-C

Deployment Procedure

Post-Deployment Checks

  1. RSSI
    1. Measure RSSI from 2 other nearby Meshtastic devices
    • Passing criteria: All 3 devices show similar RSSI
    • Rectification: Ensure RF cabling and connectors are tightened, matched types, matched polarities and not damaged
  2. MQTT Uplink and MeshMap
    1. Ensure Fixed Position has been set on New Meshtastic Device
    2. Ensure MQTT Uplink is enabled on 1 other Meshtastic device
    3. Reset/reboot New Meshtastic Device to trigger a NodeInfo/Location/Telemetry broadcast
    • Passing criteria: Node appears on MeshMap or MeshMap2 at installation site
    • Rectification: Ensure the following configuration is set, lora.configOkToMqtt: true
  3. RTL-SDR Survey
    1. Center SDR# waterfall on 919–924 MHz
    2. Take a screenshot
    • Passing criteria: LoRa transmissions at 922.8751) are visually distinct from background noise

Long Term Health Monitoring

  1. Check MeshMap or MeshMap2 to confirm node is alive
    1. Check ChUtil and AirtimeUtil statistics, if they are consistently above 25% the mesh may be unhealthy (overloaded)
    2. Check battery voltage statistics, ensure solar is sufficient to keep battery topped off
