Yes, if we provide power to the unit, it doesn’t start, we necessary need to press the pwr_key for 10 seconds to turn on the unit. Is there a configuration to change that?
for auto power on you can use different methods.
1- if you apply the voltage at VBUS (USB_VBUS) system will power on automatically.
2- you can use auto power on circuit on your board, reference design is attached.
Hi, I have the same problem.
As per your reply if I connect the module not only by battery, but by USB_VBUS, if I apply 5V to USB_VBUS after the module was powered down it will power up itself without the need to pull down the powerkey pin? is it correct?
Hi Tanveer,
sorry to bother you again! I am in contact with the quectel technical support for other questions and I also asked them the same question. They reply to me that I need to pull down the PWRKEY anyway in order to start up the module. Maybe start-up and power on are two different things? What is the truth?
Just to be clear I need to start up the module automatically and I need to have it fully functional and not only to charge the battery.
Hi,Alegioit.
i upload two video files wher
1- i power on system by connecting 5V at VBUS.
2- power on system with USB cable.
if you have any question you are welcome
