I’ve been trying to develop a mesh in my local town, including one node on a predominant hill called Denne Hill6e1c. None of the other nodes can reach each other directly without this ‘repeater’. It’s in a rural location and is powered using a 3000mAh 18650 on the back of the tbeam and a “300000mAh” X-Dragon power bank similar, but not identical to, this ebay listing:
The two are crudely cellotaped together and a short usb power cable, in a waterproof bag, hung in a tree. (looking nothing else but suspect!)
Now… a connection is made between St Leonards and Denne Hill fine, they have good LOS and can repeatedly update their location / time last heard. However Alec, as well as another node in Broadbridge heath called D3, are unable to make a connection… Untill … The power bank depletes its battery and Denne Hill starts working only from the 18650 on its back. Then a full mesh is established and all nodes can message each other consistently and successfully.
Could the circuitry in the power bank be affecting Denne Hill in some way? preventing it from relaying messages until it completely powers down due to running out of power? Is that mass of battery right next to the antenna attenuating some signals?
- To run the node with -set-router on and only 18650 battery to test run time and mesh performance.
- To run the node with -set-router on and the battery bank attached but physically separated from the tbeam by a 50cm or 1m usb cable
