Yes, all versions are the same.
Regarding the ADR, better if we use the terms Enable and Disable otherwise gets confusing.
The ADR was disabled by default and in that state got the error message. When I enabled ADR the error message ceased and the data was sent. However I can now either enable or disable the ADR and the node still sends data ok, so I am not sure what is happening.
So to summarise: I undated the firmware on four nodes and they all worked ok. I then took two of the nodes out into the field to install along with a gateway. They were working for about 12 hours then they stopped operating. When I hooked up the four nodes to the Serial Port Tool they all reported ‘send error 87’. Then I changed the DR to 5 on all the nodes but still got the same error. Finally on the gateway I changed the switch to Enabled ADR and they started working ok again. Can now either Enable or Disable the ADR on the gateway and they still work.
