To add your cellphone to the HamVOIP HDMI, follow these steps:
Connect to RJ-45 network or use HDMI monitor (best way)
If HDMI, click lower left icon and logout
If SSH, go to 123456.local -p333 (where 123456 is your node number)
Turn ON your cellphone hotspot
From the HamVOIP menu, select "Configure the WiFi Interface Networking"
1 Setup
Yes
Decide if you want to start fresh (clear wpa_supplicant) or add a WiFi connection
Manually enter the SSID? : No
Pick your phone
enter its password to connect
repeat the process without clearing
pick your home WiFi
repeat until you are done
Do NOT use your home guest network. You will likely NOT be able to "see" your node from your home network.
This means you would not view Hypermon or SSH access on 123456.local because it is, by definition, isolated on 'guest'.
