NodeId, ChildId and EEPROM

nono056 last edited by

Hye everybody!
I have a trouble...

(The sketch used is RelayActuator)

If a clear my eeprom with the sketch in the example, and if i upload a new sketch after, nothing appened. Zero message in the serial gateway and zero message in the serial of the sensor.
If i specify a NodeId, nothing else...

The solution : i clear eeprom with the original sketch of arnduino (with 0 and not 255 or 0xff) and upload a new sketch, messages are send.

If i specify a NodeId, the message is : 1;255;0;0;18;1.4
Is there a problem with my childId? why 255? and why there isn't the sketch name which appear in the serial gateway? Why is there no message when i clear EEPROM whith the "official" method?

I don't understand.

Please help me!!!!

The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle. In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V. Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work. Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).

@Yveaux I have 34 of 80k RAM used for this sketch, so 128 bytes looks like "a bit more". You can not use progmem with ESP and mysensors now because PSTR redefined as PSTR(x) (x) so all strings are really in RAM

Thanks hek, Did it a bit different, but probably with the result i wanted. In the repeaternode sketch I used the following line: gw.begin(NULL,4,true); This created a repeater node with node-id 4 (just an arbitrary number) In the Dallastemperature example I used: gw.begin(NULL,5,false,4) This created the sensor node with id=5, talking via repeaternode 4 to the serial gateway. This works. See the info from the temperature sensor being relayed to the serial-gateway. I haven't tried the method you suggested yet, but this sounds interesting of course. Wiil do that after Christmas I think. Boozz

sensor id is not the same as node id. sensor id = 255 is used for internal stuff like id request and battery level for node. You can assign 0-254 to your own attached sensors (to the arduino node).
