I have several Pi based GW’s with others in build/planned based on RPi 2, RPi 3 & RPiZeroes. Both iMST & RAK concentrators, and either Jessie Lite or Stretch OS base builds
Several will move locations over time possibly being connected to same 3G/4G MiFi backhaul net at various pop-up/demo/test sites. where others will be hosted on different WiFi nets each time.
Question - is it possible to load multiple net SSID/PWD Combo’s at build time to allow such floating deployment or its one net only at a time for any given build/config. I know you can add 2 or more USB WiFi adapters to support dual nets but can 1 interface be used to fall back to different WiFi nets in the same way a laptop, phone or tablet will ‘remember’ the various WiFi nets they have been connected to. Have just realised have never tried/seen that with a Pi!
I could just ‘try’ it and move a unit around but figured quicker/easier(/lazier?) to ask Forumites experience/advice
