I am currently trying to make my HC-05 Bluetooth Adapter (CZ-HC-05 gomcu) work with my Raspberry Pi (B+ V2, lates Raspbian freshly installed).

I used this Tutorial: A cheap Bluetooth serial port for your Raspberry Pi

But I get stuck. My smartphone seems to connect with the RasPi, but I cannot see anything on my Smartphone using Blueterm while the RasPi is starting.

I copied the content from /boot/cmdline.txt and /etc/inittab directly from the tutorial. The previous content looked like this:


dwc_otg.lpm_enable=0 console=tty1 console=serial0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

/etc/inittab: empty

Serial is enabled in raspi-config

What do I do wrong? Since my smartphone is connected I do not think I made an failure while wireing the HC-05.


Solved it! The probplem was with my adapter (T-Cobbler GPIO->Breadboard): The labels of RX and TX were switched.
