Communication with BrickPi3 unsuccessful[SOLVED]

BrickPi
1

when I run

python3 /home/pi/Dexter/BrickPi3/Software/Python/Examples/Test_Connected.py

I get the error

“Communication with BrickPi3 unsuccessful”

Why is that so?

(I run:

sudo git clone http://www.github.com/DexterInd/BrickPi3.git /home/pi/Dexter/BrickPi3
sudo bash /home/pi/Dexter/BrickPi3/Install/install.sh
sudo reboot

I checked: SPI is activated)

update:
plugging the external batteries and switching on, the yellow LED is flashing slower than before (1/sec),
but still the error message:

python3 /home/pi/Dexter/BrickPi3/Software/Python/Examples/Test_Connected.py
"Communication with BrickPi3 unsuccessful"

So what is faulty?

Your firmware probably needs to be updated. Try running Read_Info.py for more details.

yes!
firmware version is 1.0.1

I updated, now the connection is fine and the Read_Info.py appearently shows correct data.
Thank you very much!
