Ok. Understood.
Trying either option on ESP IDF 3.3 still results in there being a DNS server on 192.168.4.1, but the gateway on 192.168.4.1 disappears. Android still doesn't use cellular in this case.phatpaul wrote: ↑Tue Feb 26, 2019 4:34 pmInteresting about the Garmin device. What device is it? Does it prevent hijacking the internet connection on both iOS and Android?
Here's what I have after struggling with this as well. It seems to work for iOS, but not always working in Android.
this is in main() before initializing WiFi:Hope it helps.Code: Select all
