FranklinWH aGate Network Profile¶
Device: FranklinWH aGate X (Serial: 10060006A02F24)
Firmware: V10R01B04D
SoC: NXP i.MX6ULL (ARM Cortex-A7)
mDNS Hostname: imx6ull14x14evk (default NXP EVK hostname)
WiFi MAC: 4C:24:CE:67:3A:7C
LAN IP: 192.168.0.110
Open Ports¶
| Port | Protocol | Service | Details |
|---|---|---|---|
| 22 | TCP | SSH | Dropbear 2015.71 (SSH-2.0-dropbear_2015.71) |
| 53 | UDP/TCP | DNS | Local resolver (responds to queries) |
| 111 | TCP | RPC | Sun RPC / portmapper |
| 502 | TCP | Modbus TCP | SunSpec compliant — primary control interface |
| 9000 | TCP | Unknown | Accepts connections, no banner, not HTTP |
Network Interfaces¶
| Interface | Status | Notes |
|---|---|---|
| Ethernet | Available | Primary LAN connection (preferred) |
| WiFi | Auto-connect | Fallback if Ethernet unavailable |
| 4G/LTE | Built-in modem | Last-resort backup for cloud connectivity |
Priority: Ethernet → WiFi → 4G. If the app shows 4G as primary, the LAN interfaces have failed.
mDNS Discovery¶
The aGate advertises SSH via mDNS but does not advertise _modbus._tcp.
Key Observations¶
- SSH (port 22) — Dropbear is a lightweight SSH server for embedded Linux. Password unknown; likely requires installer/factory credentials.
- DNS (port 53) — The aGate runs its own DNS resolver, possibly dnsmasq for local name resolution.
- RPC (port 111) — Sun RPC portmapper suggests NFS or other RPC services may be available.
- Port 9000 — Unknown service. Accepts TCP connections but sends no banner and doesn't respond to HTTP. Could be an internal management or firmware update interface.
- No HTTP/HTTPS — The aGate has no web interface; all configuration is via the FranklinWH mobile app (cloud API) or Modbus TCP.
Bluetooth Connectivity (aGate v1.2+)¶
aGate firmware v1.2 and above supports Bluetooth Low Energy (BLE) connectivity for: - Installer commissioning and configuration - Customer setup where no local WiFi or network infrastructure exists - Direct device-to-phone communication without cloud dependency
Connectivity Troubleshooting¶
If the aGate becomes unreachable via Modbus TCP:
- Check the FranklinWH app → Network Settings — if it shows "4G" as the primary connection, WiFi/Ethernet have dropped
- Check WiFi IP — if
0.0.0.0, the DHCP lease was lost. Reconfigure WiFi via the app - Recommend: Set a DHCP reservation in your router for MAC
4C:24:CE:67:3A:7C→192.168.0.110
See WiFi DHCP Failure — 2026-03-21 for a documented example.
