Connecting to arm or servos through sdk

I can consistently connect to the robot through the SDK, and successfully issue commands to move the chassis
e.g.  .chassis.move(x=1, y=0, z=0), or change the led lights.  However, every time I try to either query the state of the arm or the servos, or move the arm through the SDK, I get a message like

2021-01-29 23:05:35,866 ERROR Client: send_sync_msg wait msg receiver:2702, cmdset:0x00, cmdid:0x01 timeout!

and then the robot hangs.

The arm consistently functions properly in the app; and I have done multiple iterations of connecting to robot in  the app, trying the arm (and it working), then disconnecting, connecting via wifi to python SDK, moving the robot arround with chassis commands, and then getting a hang when I query the arm.   

Any advice?
