Unable to scan Wifi networks with AmazonFreeRTS in iOS app after connecting to one

0

Hi,

I'm working with the AmazonFreeRTS library for iOS. The app I'm writing only needs to perform the function of connecting the device to a Wifi network.

I'm able to successfully establish a Bluetooth connection to my device, and I'm able to retrieve a list of nearby Wifi networks. I'm also able to connect to my Wifi network by providing its password with the SaveNetworkRequest. I can tell that it worked because I can see that the device in my router's DNS table.

The problem is that once the device is connected to Wifi, I can no longer get a list of Wifi networks in order to either see which network is connected or potentially let the user connect to a different network. When I issue the command to list networks, I get no response back from the device, not even an error.

Thinking the problem might be in my code, I completely wiped out and reset my device (it's an ESP32 dev board, so I'm able to do this using esptool) and I repeated the procedure using the demo app provided by Amazon (AmazonFreeRTSDemo). The result is the same, once I connect, I can no longer see a list of networks.

Is there some command I need to give in order to either disconnect my device from Wifi or otherwise put it in a state where it is able to scan Wifi networks again? I can see that the demo app starts the scan process by writing a 1 to the NetworkConfigControl address, and I've done the same, but it doesn't appear to help.

Thanks, Frank
