#meshchat

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?

With a #RaspberryPiZero2W & #usbhub waveshare.com/wiki/USB_HUB_HAT possible to use 4 #lora #radio #rnodes at same #reticulum #meshchat interface. Can use 4 different sets of radio parameters at one #LoRa #radio interface. Can use 1 radio with low #spreadingfactor #sf for short transmissions at high data rate for large payloads like images or accessing #nomadnet #pages and 1 with larger SF for longer range. No need to choose between #meshtasic presets meshtastic.org/docs/overview/r ! just use them all ! Magic

In a world where control of #communication networks is increasingly centralized, #DIYnetworks offer an independent alternative. This presentation shows how to build up your own autonomous #meshNetworks with low-cost hardware components and open source tools such as #Reticulum and #MeshChat. We will present practical steps for the construction, configuration and integration of sensors, communication and computing power. We are also discussing how such #networks can be used in #humanitarianCrises, such as the organisation of aid measures through solidarity initiatives.

This workshop offers a detailed journey through the world of do-it-yourself radio networks and #autonomousCommunication structures. Using an exemplary system structure, we show how to realize cost-effective, flexible mesh networks with #LoRa #RNode, Reticulum and MeshChat. In doing so, we not only dedicate ourselves to the technical requirements – such as the optimal hardware selection, antenna adaptation and network planning (keyword “Network Planning 101”) – but also consider how these technologies can be used for #humanitarian purposes, for example at #CADUS.

A friend tested this for 2 VMs with #ubuntu & simply set a #UDP interface in the settings file on #meshchat on each #VM & it works. The spreading factor (SF) 10 #rnode end point meshchat GUI sees the messages arriving at the lora SF 5 rnode via UDP, & vice versa. So the #proxmox setup has both lora SF settings for messaging images & data. The SF 5 rnode is ace for messages of about 60 KB & the SF 10 for longer range text. Both arrive at each VM. reticulum.network/manual/inter
#reticulum is sensational.

Any recommendations for a 64 bit machine for #proxmox to run 8 dedicated #virtualmachines #vm each running minimal #ubuntu for a single #reticulum #meshchat application with 8 single usb-c connections to 8 #lora radio #rnode #nodes like a RAK4613 store.rakwireless.com/products
Here is what their site says: proxmox.com/en/products/proxmo
Requirements for each VM is not much more than 1 Gb and storage requirements trivial (less than 30 Gb per machine). Any recommendations most welcome.

If I have 10 virtual machines (m1..10) in #proxmox each running #rnode hardware (r1..10), via 10 #meshchat guis (g1..10), over one of 10 respective usb-c connections,
& all 10 virtual machines are on the same local area network #LAN via 1 network card/interface of the 1 computer running proxmox, can I link the virtual machines using #reticulum #rns #autointerface
reticulum.network/manual/inter
& will thereby each #rnode #meshchat #gui receive all #lora mediated data from each other #rnode over #lan ?

@fishingdev @richardwonka @fidepus The idea behind #reticulum is ideal for emergency networking because it has redundancy & your address is kept & works irrespective of device or comms protocol: you are reachable on a unique address like a phone number. Very precious indeed in an emergency. Seamless communication. Also you can use multiple #radio settings & protocols at the same end user device. It also confirms delivery of #lora messages extremely well. #lxmf #meshchat #Notfallkommunikation

To receive by #radio #reticulum #rnode #announces on #lora radio one needs to have the same 4 radio parameters as the announce: #frequency #bandwidth #spreadingfactor SF #codingrate CR
-> #meshchat permits any number of #rnode interfaces !
To hear the most announces, does it make sense & is it possible to set up several e.g. 5 #lora #radios with same frequency: 869.525 MHz
bandwidth: 250 kHz but
each with different SF & CR? Would one be able to receive more announces that way? Would it work?

Running #meshchat , four #liion #21700 5000 mAh batteries seem to run the #rak4631 and Pi for at least 24 hours. The device can be re-charged using #usbc or 9 to 18 V DC at up to 3 A via a jack or other connector. The rnode shuts down cleanly when batteries run out & re-starts when power is back, whereupon the batteries charge at the same time in #passthroughcharging

@mrkaran Great insights & a pleasure to read. I have used #nixos as my main machine for a few years & its main advantage is that it won't let me mess it up because I do not install anything other than via the configuration.nix. Your post has given me a view on how to use it properly.
My big question: how can one #package something to get it into the nixOS search.nixos.org/packages
? I am happy to do the work but no micro step by step guide seems available. I am thinking of #reticulum #meshchat

#lora #radio #reticulum using #meshchat
If one #rnode (rnodeA) run by device A, e.g #RaspberryPiZero2W , has is its own #wifi #hotpot (as shown here loramesh.org/subpages/pi_insta) (with SSID & password),
& another rnode (rnodeB) run by another device B (any device with wifi) joins the hotspot (SSID & pwd),
& rnodeA & rnodeB both have the 'default interface' activated in their reticulum meshchat GUI,
the wifi hotspot *alone* (without radio) will enable sending messages via reticulum between A and B !

@tomjennings @Mark @phanuel @goldfishlaser Using #reticulum in #lora only #mesh using #meshchat application. It is beyond fantastic. No issues. Excellent delivery confirmation. Sends #images & #sound. When on the move with #rnode it resends messages, that failed due to no radio contact being available at the time of send, & sends them automatically later when in lora radio contact. Even re-sends chunks of images in batches as & when in lora contact again. Fab! Info: loramesh.org
