Manages port tunnels for Android and physical iOS devices.
Android (adb): adb reverse tcp:4369 tcp:4369 — Android BEAM registers in Mac's EPMD adb forward tcp:<dist> tcp:9100 — Mac reaches device's dist port
Physical iOS (direct networking — USB preferred, WiFi/LAN fallback): mob_beam.m finds the device's own IP via getifaddrs() and starts the BEAM as mob_qa_ios@<device-ip>. The in-process EPMD binds 0.0.0.0:4369 so Mac can query it at <device-ip>:4369. The dist port is directly reachable.
Connection priority (mirrors mob_beam.m priority):
1. USB link-local (169.254.x.x) — detected from Mac ARP table
2. WiFi/LAN (10.x, 172.16-31.x, 192.168.x) — EPMD scan of ARP table
3. Tailscale (100.64-127.x) — EPMD scan of ARP tableiOS simulator: Shares Mac network stack — no tunnels needed.
Summary
Functions
Returns the dist port for a given device index (same formula used in setup/2).
Assigns a dist port and sets up tunnels for a device. Returns {:ok, %Device{}} with dist_port and host_ip filled in, or {:error, reason}.
Tears down tunnels for a device.
Functions
@spec dist_port(non_neg_integer()) :: non_neg_integer()
Returns the dist port for a given device index (same formula used in setup/2).
@spec setup(MobDev.Device.t(), non_neg_integer()) :: {:ok, MobDev.Device.t()} | {:error, String.t()}
Assigns a dist port and sets up tunnels for a device. Returns {:ok, %Device{}} with dist_port and host_ip filled in, or {:error, reason}.
@spec teardown(MobDev.Device.t()) :: :ok
Tears down tunnels for a device.
