CF: hooked up GPS, now can't connect GUI without batt

Post by Cereal_Killer »

Setup:
Naze32 RCExplorer tricopter integrated FC
Cleanflight 1.9.1
UBLOX Neo 6M on softserial 2
Ports configured correctly, softserial enabled, running at 9600baud

I'm no longer able to connect to the board in the GUI without the GPS module powered on (from 5V which means the flight pack must be hooked up powering a UBEC). The GUI opens the seri port but is never able to connect. Note my board has no MAG so I'm using the one built into the GPS so I guess technically the problem could be either or (however i2C error is rock steady at 0 so I don't thing it's the mag).

As soon as I power the FC from the batt I can connect no problem. BTW I'm using softserial 2 because I'm getting a 3DR radio setup on UART2 and I have LED's on RC5 (SS1). If I disconnect either power or GND to the GPS I can connect again (but connections are soldered so it's not a simple work around).
