Sorry I think I was not clear in my post.
I have a multi Band router. SSID ‘A’ transmits at a radio frequency of 2.4Ghz, SSID ‘B’ transmits at a radio frequency of 5.0Ghz.
I have TWO devices (WIO Terminal), one (live) is running with the original atWIFI and is connecting to ‘A’ on a regular basis. The other (dev) I use for development work and is running the new rpcWIFI. When I create a new version of the application I swap the devices (live <-> dev) over.
Currently live is using the original atWIFI and connects to ‘A’ at 2.4Ghz. The dev device is using the new rpcWIFI. It does not connect to ‘A’ at 2.4Ghz. The application is unchanged. If I change the SSID of the application on dev to use ‘B’ it connects OK.
Note that MY laptop (connected to dev via USB) lists both ‘A’ and ‘B’.
To investigate I uploaded the scanner code on to the ‘dev’ device and the list did not include ‘A’ it listed only ‘B’.
My assumption is thet the rpcWIFI is the issue. I am still investigation but could do with some advice on driving the WIO to see if I can work out what the issue is.
