How do I request information from a node from the gateway?
I have a relayactuator node with 2 relays that is transmitting its initial state at the startup of the node. This is also received by the gw.
But after that I cant seem to request the current relay status from the node by sending a message from the gateway.I tried lots of combinations, nothing worked.
I thought this would be correct:
1;2;2;1;2;0\n
1=node number
2=sensor (relay number 2)
2=request
1=ack message
2=light
0=string??Can anyone point me in the correct location?
maybe a new API page for 1.4 would be handyedit: also I can't find anywhere what the debug letters mean
what is s=,c=,t=,pt=,l=,st= ??You cannot request state from a node without programming a little . I answered exactly this question a couple of posts back in this thread.

Arduino library and examples
https://github.com/mysensors/Arduino/tree/developmentVera plugin (1.4)
https://github.com/mysensors/Vera/tree/developmentHere are some of the hi-lights.
- Improved communication reliability (now uses hardware acks and resend functionality).
- Simplified sketches (only one include needed).
- Most common sleep scenarios build in.
- Helper for permanently storing values in the Arduinos EEPROM.
- Acknowledgments can now be requested from gateway and other sensors in network.
- Smaller footprint.
- The message structure has been adopted to work better on RPi platform.
- Binary payloads supported and used for integers between sensors.
- Configuration message (only metric setting in it today).
- Allow static parent (no dynamic lookups)
- Callbacks for incoming messages and time. No synchronous waiting methods any more -> no missed messages.
All examples in the development branch above has been converted to use the new functionality of the library.

(Terminology: the program flash is divided into a bootloader section and an application section; compile sketches go in the application section)
One approach is to have a separate flash or eeprom chip which one somehow fills (this could even happen at the application level). When booting, check this flash or eeprom and if valid - load into internal program flash, clear the vallidity of the external flash or eeprom (so you won't loop loading it again) and reboot. When you reboot there will be no valid image to copy from external memory, so you jump to the start of internal application flash. This takes external flash as large or larger than application flash (eg: >= 32 KiB for the 328p)
I think you are taking a different route, where the bootloader is somehow given control, after which it receives nRF packets to RAM, periodically writing another page from RAM to the application section of internal flash. When done, reboot.
If booting and there is no valid image in external memory and the CRC of the internal application flash section is valid, jump to it as usual.
I'm not sure if you can also still use serial programming.
This could be all wrong. It implies keeping (at least part of) the nRF library in bootload program flash, to receive packets. I'm putting it out as a hypotheis to help elicit the real description.
How big is the OTA bootloader?

Right now the OTA works without any need for external flash. @ToSa will have to answer the details when he's back (like size, building, serial programming).
Yes it uses a VERY stripped down rf24 library.
https://github.com/mysensors/Arduino/blob/development/Bootloader/MyOtaBootloaderRF24.hNot much of the MySensors library is needed.

I am in process of upgrading to 1.4b1 - have most things working. I noticed that my status consistently fails during setup() when presenting sensors AND also never receive a return message from controller after a time request. It's always the same two failures.
Everything works after adding a 100ms delay between calls. Not sure if there's a timing problem somewhere.
Hek - as always thanks for ALL your contributions. :-)

gw.sleep(<sleep time in milliseconds>); -
If you want to store you own data in EEPROM you can use the provided saveState(), loadState(). It makes sure you won't overwrite anything important. If 256 bytes isn't enough you can start writing at position EEPROM_LOCAL_CONFIG_ADDRESS defined in MySensors.h.

The 1.4 version of the MySenors Arduino library is new open for beta testing.
Arduino library and examples
https://github.com/mysensors/Arduino/tree/developmentVera plugin (1.4)
https://github.com/mysensors/Vera/tree/developmentHere are some of the hi-lights.
- Improved communication reliability (now uses hardware acks and resend functionality).
- Simplified sketches (only one include needed).
- Most common sleep scenarios build in.
- Helper for permanently storing values in the Arduinos EEPROM.
- Acknowledgments can now be requested from gateway and other sensors in network.
- Smaller footprint.
- The message structure has been adopted to work better on RPi platform.
- Binary payloads supported and used for integers between sensors.
- Configuration message (only metric setting in it today).
- Allow static parent (no dynamic lookups)
- Callbacks for incoming messages and time. No synchronous waiting methods any more -> no missed messages.
All examples in the development branch above has been converted to use the new functionality of the library.

You should probably not request ack back on a id-response. But I doubt that is the cause for transmission error. What is happening in the sensor node?
@hek Tried with no ack also. And the node doesn't recieve anything. I'm out of components to build myself a sniffer right now.. Might have to kill something.. :boom: I can recieve From the node though.. but the node does not read from gateway..

@hek I fixed the problem , it was the RF24_PA_LEVEL_GW .. needed to be low.
You are correct with the ack on id-response, it gets all fucked up. Stuck in loop requesting ID 10+times/second. And doesnt register the id.. Too bad. would be really good for me to know if the sensor actually got the id_response or not... (and if it's sent as node 255 or node newid doesnt really matter..)
edit:
I changed my aproach to checking if sendRoute(msg) is true. But I still have a problem that the node actually recieves the packagt but just ignored is. sometimes I need to reset the node for it to get accept the new ID.. example;0;0;3;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0: 0;0;3;9;send: 0-0-255-255 s=255,c=3,t=4,pt=1,l=1,st=ok:20 0;0;3;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0: 0;0;3;9;send: 0-0-255-255 s=255,c=3,t=4,pt=1,l=1,st=ok:21 0;0;3;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0: 0;0;3;9;send: 0-0-255-255 s=255,c=3,t=4,pt=1,l=1,st=ok:22 0;0;3;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0: 0;0;3;9;send: 0-0-255-255 s=255,c=3,t=4,pt=1,l=1,st=ok:23I'll try to look at the debug output on the node tomorrow..
