Current Appstore softAP failing to connect to device

[markirwin]

I am trying to use the vanilla softAP examples in ESP-IDF 4.3 they build fine and a couple of weeks back it worked fine with the app store softAP application to provision the ESP32.

However, I am trying to do this again since upgrading to iOS 14.5 and now the app is getting stuck.

I connect to the AP hotspot from settings, then open the ESP softAP provisioning example, Skip the QR code window and on the second screen when I press connect it takes me to the ESP SoftAP Prov settings, I have granted all permissions required. On occasion, i manage to get it to the spinning icon when I press connect but the app isn't asking for permission to connect to the network. I assume some of the privacy changes in 14.5 might have interfered in the operation?

I see from the output in monitor I (955) app: If QR code is not visible, copy paste the below URL in a browser. https://espressif.github.io/esp-jumpstart/qrcode.html?data={"ver":"v1","name":"PROV_0699E4","pop":"abcd1234","transport":"softap"} I (23185) wifi:new:<1,0>, old:<1,1>, ap:<1,1>, sta:<0,0>, prof:1 I (23195) wifi:station: ca:58:06:1a:ad:f1 join, AID=1, bgn, 20 I (24455) esp_netif_lwip: DHCP server assigned IP to a station, IP is: 192.168.4.2 W (26245) wifi:idx:4 (ifx:1, ca:58:06:1a:ad:f1), tid:0, ssn:0, winSize:64

Everytime i jump back to the app and press connect it keeps taking me back to settings.

Hi @markirwin, Thanks for reporting this issue. We will verify this behaviour and let you know.

Hi @markirwin, Can you confirm if app has permission for local network from iPhone settings? In our case we can see that local network permission dialog is not getting triggered when you try to communicate with SoftAP device. This behaviour is not consistent with the earlier iOS 14 version.

We will look into making some dummy arrangement in the provisioning library in order to trigger this dialog.

Hi Vikas,

The SoftAP setting window is triggered.

And there is local network permission but it can’t seem to find the device to connect on the network.

@markirwin Can you check if below log is coming in the SoftAP device below the QR code.

I (144485) esp_netif_lwip: DHCP server assigned IP to a station, IP is: 192.168.4.3

If its not coming then keep your phone connected for some time with the SoftAP and retry provisioning once the log is visible.

I am running softAP provisioning on ESP32S2 NodeMCU dev board.

If I scan the QR code it says to be the device cannot be connected. If I click do not have QR code and then click on connect it takes me to the settings page.

@markirwin Unfortunately I was not able to verify this on iOS version 14.5. I was using the iOS version 14.4 and after upgrade it is now 14.6. However I tried SoftAP provisioning on 14.6 and it worked as expected. We are trying to search if there was some bug in 14.5 OS which has lead to this behaviour. If possible, it would be really helpful if you can upgrade your iOS version and share us the result of provisioning on it, thanks.

After upgrading and reinstalling the app it now works.. I am not sure if it was a iOS configuration issue. I will now close this ticket.
