I would like to make a mesh network with bluetooth 4.0 BLE modules.
Which modules supports the mesh topology (eg.: HM-10, HM-11 or something else) ?
Thanks
Nice work @thedutch, thanks for reporting back.
In case you need anything similar, https://www.mysensors.org/apidocs/group__RF24SettingGrpPub.html lists the co figuration options for the nrf24 radio.
@wassfila Your project looks very cool and I considered it earlier. Thanks for sharing
I excluded it because I was concerned that you might stop developing it and that would kill the project.
I want to focus on developing sensor-nodes and using the data in openHAB.
I really think some kind of self-healing mesh solution is the way to go, especially since I want to be able to expand freely and just drop in more nodes at will without disturbing the others.
My current plan was to use MQTT-SN over openthread and then use the homie standard to get everything auto-discovered in openHAB.
But now when you say openthread is somewhat experimental I'm no longer sure.
To me openthread seemed quite well documented and I like that Nordic provide so many examples.
In your experience, is thread unstable?
I want to go for the DIY approach mainly because.
I want to be able to choose my own sensors and know that I get quality pcbs that last.
Commercial multi-sensor nodes are generally fairly expensive. Making one custom doesn't pay off, but 30+ does.
My end-goal is to make energy harvesting nodes, both indoor and outdoor, that once installed will be able to do their job until their components break.
The more I type in this response, while looking at your github and hackaday I feel like maybe I should give nrf52 Mesh a try.
Do you have any OTA working for your setup? I'm not looking for a fancy gui, just a python script on the border router or similar.
If anyone else ends up here like I did.
To drive the DIM Control pin without pulling from Vdd, try this.
This will keep the micro isolated. This assumes that you use a dual optoisolator, and that the CTR is the same. To ensure they ARE equally matched, you can buy the more expensive IL300 or LOC110 - built especially for this purpose.
Also do note: if you are going to make a DUAL dimmer, then do NOT connect the 'GND' between dimmer A and dimmer B. They must be separate.
