I recently purchased a GL 658B for my inspire, yet to arrive. When I connect the GL to the app either using the usb or micro usb using both a standard cable or a OTG I get nothing
The far left led stays red and the app just shows "how to connect". I've reset the GL using the 3 button sequence. The chap who sold me the GL insists it was working as a slave some time ago
Please help

Hi there. Thank you for reaching out and we're sorry for the trouble that this has caused. Can you please confirm what mobile device are you using with the DJI Go app? In addition, could you please try to enabled the USB debugging on your mobile device's developer option then check if the issue persitss? Please keep us posted. Thank you.

I am using an iPhone 13, have tried 2 different iPads also. I have also tried to upgrade the software using a usb stick the GL didn’t do anything with the file the led stayed red ?
