    @DAMME and @HEK

    Thanks , very helpful.

    I got so occupied with the commands and never thought about the sensor code.

    Thanks

            Hi guys,

            I just got relays working with but struggling requesting a variable value on Beta 1.4.

            My set variable commands looks as follow.

            Switching On - > 1;1;1;0;2;1 (work as expected)
            Off -> 1;1;1;0;2;0 (work as expected)

            Request variable for the same relay -> 1;1;2;0;2; (sets the relay to 0 ???)

            Can someone confirm if my request variable command is correct and if not what should it be?

            Thanks

              Pushed a few new changes/bugfixes. Sorry for the slow progress. Had to wait until we got home and had the chance to do some verification.

              • Ack bit in header indicating if message is an ack (see RelayWithButton for an example how to read it out).
              • Sleep functions now takes unsigned long. This allows sensor to sleep for than 30 sec ;)
              • Corrected string termination

                A major code drop coming from @ToSa has now been merged into 1.4. It contains:

                • The new MySensors Bootloader supporting Over-the-air sketch updates ("client"-side).
                • A simple NodeJs Controller to test the OTA stuff ("server"-side).
                • Changes to cope with new sketch meta data stored in EEPROM and conversion between serial protocol/binary data and some new STREAM command types added.
                • A new internal command has also been added to allow resetting a node remotely.

                A more detailed change log can be found here:
                https://github.com/ToSa27/Arduino/commits/development

                I haven't had time to test myself yet but everything has been verified by @ToSa and is reported working. He is on a business trip right now so advanced bootloader questions have to wait until he's back.

                  @hek Sounds like a good step forward!
                  Only one boot loader question: does this mean we can use an external boot loader or do we have to use an external boot loader now?

                  I use Domoticz as controller for Z-Wave and MySensors (previously Indigo and OpenHAB).
                  I have a FABtotum to print cases.

                    The OTA stuff is optional. But if you want to be able to hot deploy sketches over the air, you have to install the MySensors bootloader.

                              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 handy

                              edit: 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.

                                    All the zeroes indicates that something is wrong in radio communication. Check wires.

                                      • The new MySensors Bootloader supporting Over-the-air sketch updates ("client"-side).
                                        • A simple NodeJs Controller to test the OTA stuff ("server"-side).
                                          Is any instructions, how to use this?
                                          thx.

                                        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/development

                                        Vera plugin (1.4)
                                        https://github.com/mysensors/Vera/tree/development

                                        Here 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.

                                        The new API:

                                        ###To convert an old 1.3 sketch follow this guide:

                                        Include section

                                        Remove the following includes
                                        #include <Sleep_n0m1.h>
                                        #include <EEPROM.h>
                                        #include <RF24.h>
                                        #include <Sensor.h>
                                        #include <Relay.h>

                                        Add
                                        #include <MySensor.h>

                                        Global variable scope

                                        Change the following lines

                                        Sensor gw;
                                        or
                                        Relay gw;
                                        

                                        To

                                        MySensor gw;
                                        

                                        Also message containers for outgoing messages. E.g. Light level message for child sensor id 1.

                                        MyMessage msg(1, V_LIGHT_LEVEL);
                                        

                                        ####Setup()
                                        In setup() replace sendPresentation with present.
                                        Also note that begin() now allows you to add an function-argument to get callbacks for incoming messages (actuators). begin also controls wether this node should act as an repeater node. See above for full argument list.

                                        ####Loop()

                                        The sending of values looks a bit different. The old sketches could look like this:

                                        gw.sendVariable(CHILD_ID_LIGHT, V_LIGHT_LEVEL, lux);
                                        

                                        In new code you send a value by using the MyMessage contaner defined in global scope. Fill it with the value to send like this (where lux is light level in this case).

                                         gw.send(msg.set(lux));
                                        

                                        Replace any sleeping with the new build in sleep functions. The old code might have a few lines like this:

                                        delay(500);
                                        gw.powerDown();
                                        sleep.pwrDownMode(); //set sleep mode
                                        sleep.sleepDelay(SLEEP_TIME * 1000);
                                        

                                        Replace those with:

                                        gw.sleep(<sleep time in milliseconds>);

                                        I think BASE_RADIO_ID should be declared in MyCofig.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/development

                                          Vera plugin (1.4)
                                          https://github.com/mysensors/Vera/tree/development

                                          Here 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.

                                          The new API:

                                          * Creates a new instance of Sensor class.
                                          *

                                          * @param _cspin The pin attached to RF24 Chip Select (default 10)
                                          */

                                          ###To convert an old 1.3 sketch follow this guide:

                                          Include section

                                          Remove the following includes
                                          #include <Sleep_n0m1.h>
                                          #include <EEPROM.h>
                                          #include <RF24.h>
                                          #include <Sensor.h>
                                          #include <Relay.h>

                                          Add
                                          #include <MySensor.h>

                                          Global variable scope

                                          Change the following lines

                                          Sensor gw;
                                          or
                                          Relay gw;
                                          

                                          To

                                          MySensor gw;
                                          

                                          Also message containers for outgoing messages. E.g. Light level message for child sensor id 1.

                                          MyMessage msg(1, V_LIGHT_LEVEL);
                                          

                                          ####Setup()
                                          In setup() replace sendPresentation with present.
                                          Also note that begin() now allows you to add an function-argument to get callbacks for incoming messages (actuators). begin also controls wether this node should act as an repeater node. See above for full argument list.

                                          The sending of values looks a bit different. The old sketches could look like this:

                                          gw.sendVariable(CHILD_ID_LIGHT, V_LIGHT_LEVEL, lux);
                                          

                                          In new code you send a value by using the MyMessage contaner defined in global scope. Fill it with the value to send like this (where lux is light level in this case).

                                           gw.send(msg.set(lux));
                                          

                                          Replace any sleeping with the new build in sleep functions. The old code might have a few lines like this:

                                          delay(500);
                                          gw.powerDown();
                                          sleep.pwrDownMode(); //set sleep mode
                                          sleep.sleepDelay(SLEEP_TIME * 1000);
                                          

                                          Replace those with:

                                          gw.sleep(<sleep time in milliseconds>);

                                          Could we get a description of how the OTA programming works?

                                          (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?
