Gripper failed to calibrate

Hello,

In our lab we have the Baxter two finger gripper attached to a Sawyer.

In the past couple of weeks , using the gripper_keyboard.py example in the intera_examples (from the intera_sdk ROS packages, https://github.com/RethinkRobotics/intera_sdk/blob/master/intera_examples/scripts/gripper_keyboard.py ) has been throwing the following error : "Calibration failed.".

It is unclear why this has started happening after a couple of years of operation without issue.

This is a problem because we then cannot use the gripper (The error happens in any script when instantiating the Gripper class in the intera python api for the first time :  https://rethinkrobotics.github.io/intera_sdk_docs/5.1.0/intera_interface/html/index.html  ).

We noticed that running the gripper_keyboard.py over and over again generally results with it finally working after some time. Moreover, once it works, then it is not a problem again until the robot is rebooted.

Any ideas what could be happening or how we could fix this? We are starting to suspect a hardware malfunction.

Many thanks
