I have a Quectel L76K GNSS chip connected via UART to my controller. After succesfully initializing the GNSS chip I’m to receive information over the UART. However, when I try to send any command to the GNSS chip, it doesn’t react to them (I neither received and acknowledge nor the chip does what is suppoused to).
I’ve also tried to send commands through my PC (just to discard the possibility that the baudrate in my system is not accurate enough), but so far no success. I receive information from the GNSS module, but when I send commands the GNSS module doesn’t react to any.
Does anybody has a suggestion?
