Thanks and nice to work with you. Possibly others who have tried had similar problems we just had connecting with a Kerlink at long range. All my testing has been done 'point blank' with a M-CARD+PI solution. The next step is to add some more intelligence server side and get my head around the spread factor and adaptive rate. Nice you were able to OTAA Join and receive by moving closer though so I know the basics are in place also with a Kerlink gateway.
Thanks for the feedback.
