Device connected in wifi to an esp module, obviously without internet connection
I need to retrieve data from an ftp server using mobile data connection, but seems the device only use the wifi with no success, ignoring the mobile data channel
Any suggestion? wifi connection cannot be interrupted, must be always stay on..
I've already tested the suggestion you gave, but as you say it's not reliable. seems to be a no-solution problem. In my case the device always prefers the wifi connection without active internet. and it's pretty stupid even when the ftp request is obviously sent to the web....
better search for a different approch..
- Connect to the ESP with a USB cable + USB to serial converter.
- Connect the ESP to the device adhoc network.
- Connect to the ESP with Bluetooth.
- Connect both the device and ESP to a local network.
