Adeept RaspArm servo issue's

1578942552

I am having zero luck getting the servo's to debug  on the 4-DOF Robotic Arm kit
I am using a PI 4 with raspbian buster and managed to install rasparm/setup.py and have SSH connection but no matter what i do it will not activate the servo's. i cannot use old version as pi 4 only uses buster ?

Am i missing something ?

pi 4 is fine. You can use SSH to connect to the Raspberry Pi and use the command
sudo python3 rasparm/server/server.py
to run server.py manually. In this way, the servo will automatically return to the original position.

this does not work either. i get this message

Ok, i traced the error to faulty (loose) green sda wire to iic int module.

will report if i have more issues....

My setup:
1.  driver board installed on v4 raspberry pi. Servo connected to first position nearest to the battery connector. Battery connected to driver board. Nothing else connected.
2.  all software installed as instructed in Manual-Adeept_RaspArm.pdf. I did the automatic setup installation but had servo problem so I also did the manual install except I did not do the "Add the RPi Car program to auto-start" section because I have a RaspArm not a car.

After powerup, the servo never moved. I tried other servos but they did not move either.

I tried the command: sudo python3 rasparm/server/server.py
but I got the same error as user 1578942552.  
Here's what my session looked like:

root@raspberrypi:/home/pi# sudo python3 rasparm/server/server.py
Traceback (most recent call last):
  File "rasparm/server/server.py", line 28, in <module>

    self.bus.write_byte_data(self.address, self.PWR_MGMT_1, 0x00)
OSError: [Errno 121] Remote I/O error
I also tried: sudo python3 rasparm/server/server_beta.py but I got the same error no servo movement.
I started a new thread in case this one is no longer being seen:

The handle needs to be connected. The reason for the error is that the MPU6050 cannot be initialized and the MPU6050 is in the handle.
