Using motioneye video clients on Raspbian & a BATMAN-adv Ad-Hoc network

link: BATMAN Open Mesh
The Pi Zero uses an onboard BCM43143 wifi module. See above for the data sheet. We can expect around a ~19 dBm Tx signal from a BCM43143 if we are optimistic. Unfortunately, "usable" Rx gain is unclear in the context of the Pi.
This implementation of motioneye is running on Raspbian Buster (opposed to motioneyeos).
Calculating Mesh Effectiveness w/ Python:
Please take a look at dBmLoss.py- the idea here is one should be able to estimate the maximum plausible distance between mesh nodes before setting anything up. It can be run with no arguments-
python3 dBmLoss.py
...with no arguments, it should use default values (Tx = 20 dBm, Rx = |-40| dBm) to print this:
you can add (default) Rx Tx arguments using the following syntax:
python3 dBmLoss.py 20 40
python3 dBmLoss.py <Rx> <Tx>
57.74559999999994 ft = max. mesh node spacing, @
Rx = 40
Tx = 20
Try a few values from a shell or take a look in the file for more info.
Order of Operations:
All shell scripts should be privileged to match chmod u+x and assume a Raspbian Buster environment.
See ./motionConfig.sh to configure motioneye.
See ./batmanConfig.sh to install & configure BATMAN-adv.
See ./batmanRC.sh to initialize the network
See batmanBATSpace.service for a systemd service framework
