Oh, I hate saying I've noticed this great piece of software just now! It would have saved me countless hours of software tinkering, giving more eyecare for better soldering...!

Hi there,
I'm resuming this old topic 'cause I'm trying to make a dockerized version of MySensors gateway, built on a debian image. It compiles easily, but I'm stuck on transport initialization. No one tried it?
Since I'm quite new to this, I can't give now a github link, but I'll do ASAP, so we can collaborate on this.

Hi there! I'm upping this old thread to avoid duplication.
I got a UDOO-x86 (this board: https://www.udoo.org/udoo-x86/)
Very powerfull, capable of running Docker without a hitch, and it has an Arduino 101 onboard. It could be a great MySensors gateway!
So, anyone tried it?

Thanks all,
Marco

@bbastos said in BME280 node not sleeping:

Hi @ghiglie I'm still beginning in all this, but I think you need to call nodeManager.setSleepMinutes(minutes) otherwise the node will still awake.

Oh... I feel so dumb! Thanks @bbastos , I didn't ... know it. I don't know why, maybe on the solder/flash/test/upload frenzy I read that part of documentation. So, as usual, I'll RTFM and report back. Thanks again!!!

@sineverba said in Building a Raspberry Pi Gateway:

Hi to all,
I'm testing an ethernet gateway on RPI3, with nrf24 + 1 node with a relay.

I want introduce security and signing. On Arduino gateway / node no problem at all, but, how to do on the RPI3 as gateway?

I would get / create / set a software serial on PI itself and whitelisting it on the node, after I will introduce the AES Key and signing.

Cannot find in documentation how do it on PI3. Thank you very much!

Earlier in this forum... https://forum.mysensors.org/topic/4803/building-a-raspberry-pi-gateway/350

I'm quite a noob, but totally with the NRF. Interesting PCB, I'll try asap to put a sensor together!

That's not a bad test bed!

I'm having some "headaches" still. The PIR isn't sending the V_TRIPPED 0 , so I know when there's moving but not when it stops - I can manage it via HomeAssistant anyway.

@Nca78 said in NModule:

Haha that's a lot of boards. May I know what the accident was ? There was a case of a nmodule having a shortcut when manipulated, is it something similar ?

Oh, easy! I already had soldered TX/RX pins and the angled ones (towards the atmega). I decide to take them off and reverse the angled... Iron's temperature was quite high... Some tracks got as bright as old 100W bulbs filament!

The radio SPI pins can handle 5V but not it's power supply. So as you have no regulator on radio for these boards, I see 3 choices :

1. best one = use a programmer running at 3.3V and you can power the board & radio with it. 100% safe. You can do this with the ArduinoISP sketch, a 3.3V pro mini and a ftdi adapter.
2. if you only have a 5V powered programmer, power the board separately and connect only the SPI pins with the 5V programmer. But this is out of spec as the voltage on SPI pins will be higher than VCC + 0.5V
3. open the JRDIO jumper so that the radio is not connected to VCC and use 5V programmer for SPI pins + power supply of the board. In that case to respect the datasheet of NRF24 you need to supply separately at least 3V to VCC radio, else you are in the same situation than point 2, but with the radio and that is I think a worse situation so in that case solution 2. is safer.

I'm yet programming it with ArduinoISP on a genuine UNO, so I'm safe. I'll solder the SMD antenna ASAP, the TH one isn't bearable once you see how slim the node gets with your PCB!

Ok, just for record: be very very very very very carefull when desoldering the regulator+led+resistance. Do it before soldering the ping legs on module: I had a pair of nodes, correctly running, beatyfully soldered, legs trimmed... and darn, dunno what I did on tracks, they are not powering up anymore.
Luckily I could desolder the antenna from under the PCB and stick on another (the first I told) and put the other as spare.

Oh, I love DIY when I fix my errors!

{update: one sensor died yesterday. Maybe my Minis are too cheap? }
