I got 3 cores, 2 of them with u.Fl connector and 1 of them chip antenna. I have setup cores with u.Fl easliy and they worked without issues with my company’s router. But when I try to connect core with chip antenna I got an issure. After setting wi-fi credentials core can’t connect to wi-fi. It blinks green cyan green and so on never breathing cyan.
I decided to make a factory reset or firmware upgrade. But I am unable to get into Factory Reset and DFU mode when I try to hold both button and release RESET button and then the green led started to blink instead of yellow led.
I’ve searched forum but not found a similar issure.
Do you have any suggestions ?
