[SOLVED] MySensors Raspberry Pi Gateway + Domotics Controller

[eiten]

So the sensors do not receive Messages from the gateway, but not from other sensors. Is the nrf24 on the gateway a module with PA? Then maybe test different PA settings, this helped once on a setup here.

@eiten based on the suggestions "leaning towards" powering the rf24 from you and @mfalkvidd l fed the radio a regulated 3.3 with LD33V and l also brought the capacitator near the radio... yet I still cant register the nodes.

Pls what does "TSF:CKU:OK:FCTRL" mean?

@Eme said in MySensors Raspberry Pi Gateway + Domotics Controller:

TSF:CKU:OK,FCTRL

Uplink OK, flood control prevents pinging GW in too short intervals

[Eme]

@eiten Yes what does that mean in English: :blush:

[Eme]

@eiten Don't know if the Pi model matters. I used a Pi Model A with wifi.

[eiten]

@Eme did'nt I write English :grinning:
So, if you look at the source:

bool transportCheckUplink(const bool force)
{
        if (!force && (hwMillis() - _transportSM.lastUplinkCheck) < MY_TRANSPORT_CHKUPL_INTERVAL_MS) {
                TRANSPORT_DEBUG(PSTR("TSF:CKU:OK,FCTRL\n"));    // flood control
                return true;
        }

The transport prevented an uplink check, since the last was done less then MY_TRANSPORT_CHKUPL_INTERVAL_MS milliseconds ago (defaults to 10 seconds)

Sure? AFAIK A had no WiFi. Or do you use a USB dongle?

[Eme]

@eiten l think it's A+ it has Wifi and l run it "headless" with my old Nano Gateway connected to the 1 USB. But I'll looking forward to getting the Pi to work as both Gateway and Controller.

I want to use a prototype board and drop the long lines. Plus I'll also bring the cap closer to the nrf24 to see if that helps.

[eiten]

@Eme i usually solder a tantalum directly to the pins on the top side of the board :blush:

[Eme]

I have good news. I used a small prototype board for everything. made sure no line was more than 6 inches long. I soldered (My soldering sucks!) the capacitator right next to the radio and Bahm! Domoticz picked up all powered devices. :grinning:

Lessons learnt, keep length of your wires short, nRf24 MUST have a decent capacitator to smoothen out power. Don't rely on GPIO pins to power it, use a regulator. Though help may come from all and sundry, its all up to you to check their suggestions... Thanks all for helping me.

I can finally retire my Nano-Serial Gateway! Wont be upgrading for a long time to come :sneezing_face:

[mfalkvidd]

Great work @Eme! Thanks for reporting the result.

[Eme]

@mfalkvidd so how do I change the title to reflect "SOLVED"?

[Yveaux]

@Eme I did it for you, but next time choose to edit the top post, and change the topic

@Eme Thanks for letting us know how you solved the problem - helps us all to learn. I've recently upgraded my Raspberry Pi 1b to 4 and just got it working as an ethernet gateway with standard NRF24 radio. I'm curious about a few things as I've been trying to also use a PA LNA radio but without success;

• Any reason you have set up your gateway as serial and not ethernet?

• What did you mean by "Don't rely on GPIO pins to power it, use a regulator". By regulator did you mean the capacitor, did you use another regulator component - I can't see from your image

• Did you change the power setting of you configuration file MyConfig.h -lowering the power to "RF24_PA_LOW'?

@zookazim so sorry I haven't been on here in years. I actually left the IoT nodes for a while. I was running into so many issues. To answer your question... not sure if it's still required or even relevant.
