Re: Drawing current from RPi USB power supply

My circuit needs 5V; currently it is receiving this from a 9V battery being voltage regulated by a 7805. It was my thought that the GPIO pins could not source more than 16 mA. My 20 mA circuit actually seems to not draw more than 11 mA, but I am allowing it some headroom, thus considering it 20 mA. ...

Drawing current from RPi USB power supply

Hello -- I am making a device that is composed of a RPi 3 and another circuit that draws max 20 mA. I want to power both devices from a single wall supply; the RPi schematic shown below shows that PP1 is accessible before the F1 fuse. I am going to use PP1 as my 5V lead to my 20 mA circuit, and also...

Re: RPi3 to RPi3 bluetooth file transfer

They don't connect because Pi's don't by default run any connectable services. You'll need to install and run either obexpushd (for OBEX push object) or obexftp on the receiving Pi. Re-pair them once the server is running, to pick up the new service. You should then be able to send files with bluem...

Re: RPi 3: Bluetooth: unable to send file to Windows 10 lapt

SOLVED: In the bottom right-hand system tray of my Windows 10 machine, I just opened the Bluetooth icon, and clicked Receive File, and then the laptop just waits to receive the file. Then, in my Blueman GUI window, I click the laptop which is already paired and connected, and I select to send file. ...

My bluetooth hardware seems to be working properly, but I have not been able to send files between this Pi and another Pi, or between this Pi and laptop/desktop computers with bluetooth. 1) Did you install a clean image, or did you update? This RPi came installed with Raspian/Linux 8 Jessie as far a...
