How to Connect a VenusGX to VRM using an Apple iPhone 6 from a sailing catamaran at sea.
Initially I tried using the built-in WIFI. Configured the Venus and could 'see' various local WIFI networks. Turned on my iPhone WIFI and then my 'hotspot'. Tried connecting to my phone which was about 1 m away from the Venus and I could 'see' the phone. It took a while to finally show that it would not connect and failed.
I have a USB WIFI (Victron) so inserted that into the Venus and re-booted it. Logged in again using the local web server [(WIFI to Venus and then Safari to IP address)]. The signal strength of my phone (hot spot) was now full - up from 60%. Selected my phone name and then used the local keypad on the Lynx to select and enter the password. (Note here - you can use the computer keyboard - the local up down/left right and enter wheels are cumbersome). Entered <return>.
The screen jumped back to the <phone> name screen and it took ages to finally 'Connected'. At that point I changed my wifi connection on the MacBook leaving the Venus connected to my phones hotspot.
Changed my connection to another hotspot (my wife's iPhone) - logged into VRM and there was my installation - all the devices up and working. Did some software updating and downloaded some Mulit Settings using remote VE.Configure on the VRM website.
All working great (from East Coast Australia - Gold Coast).
