The issue is related to over termination, as Here3+ has terminators enabled by default, and old firmware we haven’t had an option to disable the terminators. I have pushed a new Here3+ beta firmware where its added to the parameter and set to off by default. Please use Mission Planner to update the firmware (select Beta) and see if it fixes your issue. @ceng @Kalai_Selvan . You should see the firmware version to be 1.10 after update.
