💬 FOTA (Wireless Programming)

[seeers]

is it possible or planned to do a OTA update over RS485 (with external flash using DualOptiBoot) ?

Has any attempted to use a usbip client on Windows to use with MYSController and access the GW?

usbip is another technology for sharing USB ports over TCP/IP networks, similar to virtualhere. I am using it to access a USB device connected to a rPi2 from a linux box.

Is the sensbender micro already preloaded with the Dualoptiboot bootloader?

I'd like to try this on my Pro Mini clone, but unfortunately I find the instructions very confusing.

What are fuses and why do I need to change them? To what do I need to change them?
I cannot see "Arduino Mini pro MYSBootloader" in Boards.

I am using Mysensors 2.1.

@maghac - https://forum.mysensors.org/topic/3018/tutorial-how-to-burn-1mhz-8mhz-bootloader-using-arduino-ide-1-6-5-r5 here is a good tutorial how to burn a bootloader. You need to select a bootloader you want to use. They all have different properties. The fuses are burned when you burn the bootloader. The wirelsess programming tutorial is found here: https://www.mysensors.org/about/ota

The suggested bootloader programmers in the article work with all Arduino Mini pro, UNO, MEGA and so on? I have searched around Aliexpress for "USBASP" but it seems they support only windows 7 and the common description is " USBASP USBISP AVR Programmer USB ATMEGA8 ATMEGA128" so it's kind of confusing for me

[tbowmo]

They should work with all of the "old" AVR line of atmel processors (attiny, atmega)

If you go with newer processors like atsam procssor line, you need to have a CMSIS adapter instead.

Btw. they should work on both windows and linux (and newer versions of windows as well)

Hi there,
I have a RPI running my gateway(/dev/ttyUSB020) and domoticz is running on the rpi too. How do I used MYSBootloader to push sketches to my sensors?
Thanks

@hiddenuser https://www.mysensors.org/about/ota
Then I suggest you configure the gateway as an ethernet gateway and use myscontroller to assign the firmware to the nodes

[bilbolodz]

It's not quite clear for my how to use MYSBootloader for OTA. I'm running Domoticz as a controller (on RPI) and my gateway also is running on RPI (NRF on GPIO). Should have I one more arduino gateway connected to Windows machine running MYSController? As far I know there could be only one gateway in mysensors network.

[gohan]

You just connect myscontroller to the gateway running on the RPI if it is configured as ethernet

[maghac]

I installed mycontroller.org for this purpose (OTA updates).

I have a MQTT gateway running on a NodeMCU, which connects to my MQTT server (mosquitto running on a ubuntu server) via wifi. This setup works very well, and I don't have to keep anything running on my desktop machine (which is a windows 10 box) while the OTA updates are being pushed out (which takes ages, since they are running on battery and only wake up once every few hours).

lately I was also tinkering with the OTA updates. I'm using RPI as a gateway and controller at the same time. I'm using MQTT gateway and the controller software is OpenHAB. As I studied the documentation about OTA I learned that it is not working with MQTT gateway. Can You explain how to setup OTA with MQTT gateway ? For now I have to kill the MQTT gateway process and launch serial gateway with virtual serial port which in turn has to be shared through the network with the ser2net to be able to use it with mycontroller running on my desktop.

Not sure what I am doing wrong here,... I followed the instructions for bootloader MYSController using an 'Arduino as ISP',... now when trying eg. the Blink sketch, I see that it takes about 10 seconds before it starts and after some 'blinks' it seems to miss some 'blinks',... any suggestions what might be wrong? The normal optiboot seems to work fine...

[maghac]

I just enabled OTA on a non-sleeping node - it doesn't call smartSleep() and the loop function is mostly empty (except for sending one initial message). I do have a receive() function since I need to respond to incoming messages.

How can I properly enable OTA in this kind of node? Sending the "New firmware" command in MyController sends the message which gets caught by receive() and just gives me an error message since it's not one of the message types I expect. Telling the node to reboot sends it into some sort of endless loop which I cannot break unless I kill power to the board.

@maghac did you see this? https://forum.mysensors.org/topic/6769/node-reboot-issue/7

[maghac]

@gohan Thanks. I seem to have the same issue and I'm also using a 5V pro mini, although I actually am using the MYSBootloader.
