OTA firmware update with external MQTT broker



  • Great, thanks again @jkandasa!

    I tried this and got it to work, however, some clarification is still needed as my results are inconsistent.

    First thing I noticed is, when the .hex file is generated by the Arduino IDE two .hex files are created:

    • SketchName.ino.hex

    • SketchName.ino.with_bootloader.hex

    Which one should be uploaded to the MyController Firmware section? Does it matter?

    Next, a little more clarification on the update process...

    Once a new version of the firmware is uploaded into MyController, how do we push that out to the node?

    I know there is an option to select the node and then from the Actions Menu choose "Upload firmware". Does that initiate the upload immediately and refresh refresh the node or must a "Reboot" be selected after pushing "Upload firmware"?

    If a reboot is needed, can it be done immediately after choosing "Upload firmware"? If not how long should we wait before clicking "Reboot"?

    I'm able to get the updates out eventually but that is just because I keep clicking reboot and upload, and even resetting the node manually. That seems like a poor way to achieve what I am doing. There must be a certain order to doing this with consistent results. I would like to know what part of what I am doing is actually necessary and what is not.

    Can you please provide a step by step guide.

    Also, is there any way we could monitor the Firmware Upload progress in MyController? That would be very helpful. Should I add that feature request to GitHub?



  • @imedia First I would explain supported boot-loaders. For now AFAIK MySensors supports two type of boot-loaders,

    1. MYSBootloader
    2. DualOptiboot
    MYSBootloader:

    This boot-loader does not required any external memory. This boot-loader occupies approx 2K of memory on chip. It is isolated completely from actual program. When you reboot your node(Arduino board with MYSBootloader) It sends current available version of Users firmware to controller. Controller checks locally and respond with what firmware node should have. If node do not see any different on controller response. Boot-loader changes control to users program. Now boot-loader goes away from actions, all the control goes to users program. Boot-loader gets control only on next reboot of node.

    DualOptiboot:

    This boot-loader comes along with users program. This boot-loader needs external memory. This boot-loader never request firmware configuration from controller. If controller sends firmware configuration, it reads local configuration and if the received one is different receives the firmware from controller and stores on external memory. Once it receives all the firmware bytes successfully. Reboots the node, on reboot node checks external memory with some flag. If there is a flag enabled, copies firmware from external memory to actual program memory space and starts with new firmware.

    This is how both boot-loader works.

    • When we use MYSBootloader, we need to reboot the node to update new firmware.
    • When we use DualOptiboot , we need to click Update firmware for the node.

    You have to use always use the firmware without boot-loader (SketchName.ino.hex). I hope now you I have cleared your confusions.



  • @imedia @jkandasa

    Thank you for your explain. I didn't know how DualOptiboot works.
    However if your node is battery powered and has sleep mode, it may work differently.
    Mysensors 2.0.0 library has smartSleep() when it wake up, wait 500ms to get command from controller. (You can change wait time from config)
    You can place reboot command when node send heartbeat.
    I use node-Red to send reboot command because MyController current official version doesn't support this.

    I'm not sure how firmware update function work battery powered node with DualOptiboot.



  • @yd in SNAPSHOT version we have smartSleep support. If you issue reboot, command will be on queue. When it receives heartbeat from node, sends queued commands to that node.



  • @jkandasa Is there any easy update Snapshot version. Just overwrite all files?



  • @yd SNAPSHOT build is available here with upgrade instruction.



  • @jkandasa ,

    I loaded your latest snapshot, I am not getting the following error, OTA firmware update no longer seems to work either.

  • @imedia Thanks to report this. Let me have a look.



  • @imedia I do not see error on my side, Could please post screenshot of firmware page, As shown here,

    0_1478708296561_upload-d89ddd46-20f6-4f9b-b6f2-6da4f1389a51



  • 0_1478710137914_upload-a47deee1-deee-4f89-9c8c-f66c6425ae29

    Not sure what is up, I rebooted flashed the bootloader again on the node and deleted re-added the node and now it works. Also not getting the error either.



  • I've been testing more... It seems that in order for the new firmware to be loaded to the node and then show as running in MyController the node needs a hard reset (pull power and restore). Issuing reboots from the controller does not seem to work.

    I've yet to figure out what combination of things is actually triggering the update though. I just keep trying different things and eventually it works. But consistently the new firmware version will not be shown in MyController until a hard reset on the node is completed.

    I'm using 5v 16Mhz Pro Mini.

    I've also noticed that once the firmware version has been put on a node I can't re-send the same version, I need to increment the versions everywhere. Is this correct or should I be able to re-flash with the same firmware version by issuing the command?



  • @imedia said:

    Issuing reboots from the controller does not seem to work.

    I do not know what causes this issue for you. Hence I could not reproduce this issue locally in my environment. I am using pro mini 5 volt cloned version and MySensors version 2.0.1-beta

    I've also noticed that once the firmware version has been put on a node I can't re-send the same version, I need to increment the versions everywhere. Is this correct or should I be able to re-flash with the same firmware version by issuing the command?

    Yes, this is known limitation on MySensors. To avoid firmware update on every reboot. If you have any changes on your firmware, your CRC will be changed. Then node will consider it a new firmware. Node will check three things type, version and CRC, if either once is changed node assumes that there is anew firmware available for me and run firmware update.



  • @jkandasa Hi jkandasa,
    I did upgrade with SNAPSHOT version from google drive.
    Seems it works fine but I'm unable to select firmware from node. There are many firmware in utilities.
    Do you know this issue?
    Thank you in advance.



  • @jkandasa Oh, it works now. I have to restart after restore from backup.
    After restart server then I'm able to see all firmware^^ however I can't see smart sleep option on firefox.
    I can see it on chrome.



  • @yd Thanks to report this. Could you please remove your browser cache on firefox. It could be a firefox browser caching issue.

    Please report SmartSleep support status with MyController. I didn't test this feature as I do not have any SmartSellp node.

    Thank you!



  • @jkandasa You are right. It's working now after clear cache. There is no plan to firmware upgrade at this moment. I will let you know when I do test this function.



  • I can confirm smartsleep works fine with mysensors 2.0.0 (battery powered arduino pro mini 3.3V )
    Thank you for your support! This is awesome controller!



  • @jkandasa

    Hi SmartSleep is now working for me thank you this is great I haven't yet tested all the commands but have noticed you are forced to enter a sensor ID as well as the node id on internal commands such as reboot and present when the sensor id is not relevant.

    I have also noticed that the name field doesn't seem to get updated when a presentation request is made after first registration. This may be intentional though as people may wish to display a different name to that presented. May be worth having a name field and a known as field just a thought.

    I'm attempting to get OTA updates working using dualoptiboot. I have it operating using MYScontroller so know the nodes are accepting the firmware ok. In your post you mention for dualoptiboot you need to click Update firmware. Any help on where I may find this in the UI would be appresiated.

    On a testing front I have noticed a few small niggles one of those being the filter and sort options at the top of each page don't seem to persist past page refreshes.

    Hope this is helpful



  • @Doug

    I haven't yet tested all the commands but have noticed you are forced to enter a sensor ID as well as the node id on internal commands such as reboot and present when the sensor id is not relevant.

    I hope you passing commands via Send Raw message page. Which is not require. Suppose if you want to reboot smartsleep node. Just select that node on Resources >> Nodes >> your node on actions click on Reboot. This command will be send to SmartSleep node when it talks to MyController.

    I have also noticed that the name field doesn't seem to get updated when a presentation request is made after first registration. This may be intentional though as people may wish to display a different name to that presented. May be worth having a name field and a known as field just a thought.

    Yes, this is addresses on this requirement. However if your node sends some name will be overridden. It will not change only when node sends NULL or "" no values.

    I'm attempting to get OTA updates working using dualoptiboot. I have it operating using MYScontroller so know the nodes are accepting the firmware ok. In your post you mention for dualoptiboot you need to click Update firmware. Any help on where I may find this in the UI would be appresiated.

    I believe it should be on user manual. And here is the steps.

    • Update your firmware under Utilities >> Firmwares
    • Edit your node and select your uploaded firmware for a node [Resources >> Nodes >> select a node and on actions Edit] finally save the configuration.
      *MyController ready to send your firmware to your node. Select your node under Resources >> Nodes >> your node and on actions select Upload firmeware

    On a testing front I have noticed a few small niggles one of those being the filter and sort options at the top of each page don't seem to persist past page refreshes.

    Yes, This is known limitation. If possible I will address this. Kindly create a ticket on github project page

    Hope I have addressed your queries.



  • I am very new to this. Sorry for stupid questions.

    @jkandasa I have still issues with OTA. It is uploading spontaneously to a wrong node? Anyone here has maybe a bootfile for 8MHZ node which should work correctly? (Also serial works?) and is there a clear description of how it should work. I have added the firmware but if I select the node and upload firmware I cannot select the firmware version only with the edit mode.

    Thanks for any help.
