Development

Hello, Fresh update: With 5k1 pull-down resistors the reel switches work as expected (with the diode "OR"), so I can keep the original plan and use the MySensors sleep methods. Thanks for that tip! And by the way, is it possible to configure the MySensors interrupts on the rising edge, or is it just limited to change? However, with the PIR (modified to work at 3.3V) the maximum voltage it reaches with a 5k1 pull-down resistor is 2.2V, witch is still not enough to activate the interrupt. I kept increasing the pull-down resistor up to 20k, but then the behaviour gets erratic: It starts activating/deactivating without any sense. Was anyone been able to use a modified HC-SR501 PIR (initial diode and 3.3v voltage regulator bypassed) successfully, or the step up to 5V is really needed? (Its a shame to step up 3.3v to 5v so then step it down again to 3.3v, but if there is no other way...). Anyone willing to share the experience with HC-SR501 PIR's in mysensors framework? Thanks, Joao

Repeater nodes keep a list in EEPROM on where to send messages (next hop) so they'll reach the final target. This table is kept updated by inspecting messages arriving to the repeater. You'll probably have to look in the code for more details.

Ok, the use the development branch. And something like: MyMessage msg(1,V_TEMP); int temp; void presentation() { present(1,S_TEMP); } void loop() { temp = READ_TEMP_FROM_SOME_SOURCE; if (temp>25) send(msg.set(temp)); wait(10000); }

No clue :(

That simplifies my issue. I was trying (and now succeeded) to handle 160 char SMS messages (with DEBUG off), but the payload of S_INFO is the limiting factor. So now I can use a 30 char buffer AND keep DEBUG on, which is better for development. I will try to set up to git on dropbox, it is indeed transparent for my PC, not so sure about the Mac. And I still need to do the writeup for connecting the NRF24 directly to the Raspberry as a gateway :-)

@gopal_N Apart from the question why you would choose such a setup, it can be done by programming the Arduino as serial gateway and using the ESP8266 as serial-to-WiFi bridge.

Hmm. that should't be included at all for MQTT gateways. Thanks for spotting. Or maybe I misunderstand what you're trying to do.. Please open a chat.

@Oitzu Well, What I want to do is; Make gateway my controller ( intend to use arduino yun), the reason for that is none of the controllers fit my need, which is I want to automate hydroponic greenhouse and it is something like this ; https://www.youtube.com/watch?v=-IfvbrZJ4sY I want to ask again " How do I pull data to use in my controller code in gateway instead of forwarding to Raspberry PI. Can you help me with a simple code showing how it can be done?".

Ok thank you very much! You were right. Today my Caps came and now it's working perfect! :heart_eyes:

Ok ;) Looked at the code earlier but couldn't find anything wrong.

Been trying to combine servo and light sensor, but running into a few kinks with the sketch. Any chance you could post your finished work? Thanks in advance. -Patrick

@Lars65 aha! Great to hear you're enthusiastic about the site and MySensors development! I totally share your enthusiasm :-)

That worked previously because the MySensors class inherited RF24. In 1.5 you can initialise a radio driver which has a sleep method that calls powerDown() (in the RF24 case). The radio automatically wakes up when sending a new message.

@TheoL Thank you very much, really helped me, now the program code work :smile:

@jgporteous said: 101;4;1;0;3;0 Added ACK to one of my senors, node sending values correctly, but ACK failing. I've bumped up the CAP on the gateway to 330uF and no change :( I also dropped bandwidth to 250Kbps and power to low, no change either.

@TheoL a simple capacitor to ground is sufficient in most cases. If you use the Arduino internal pull-up a you only need a capacitor of around 300 nF to 1 uF.( the "100" value in the schematic) [image: 1443440763506-upload-53d39f96-249f-4900-b3b0-8cf81b7e09cc]

I think my biggest challenge is understanding when to combine the additional sensor in the main loop or when to put it in another. The whole idea of interrupts is baffling to me too.
