👾If a #reticulum #meshchat instance with a #lxmf address on one computing device has 4 identical #lora #rnodes #rnode interfaces, each with same settings of frequency #spreadingfactor #sf, each rnode having a #directional #yagi #antenna in close vicinity, will transmission to a sender of a #deliveryconfirmation (#downlink) from 1 antenna to the sender's direction, be messed up due to local #collision at rnode 1 of different attempted #acknowledgement signals of the other 3 near rnodes?
One can test this in the field by switching off 3 rnodes and seeing if a delivery confirmation is more likely. Will try but need a remote control on my Pi Zero that runs the instance. That I cannot do by LAN ssh directly as the Waveshare USB-A (B) HAT blocks LAN so will need to link to a separate remote controlled computer at home which can the ssh into the Pi Zero over the Pi Zero hotspot.... 🐰 🕳️ 😁
