💬 FOTA (Wireless Programming)

[Tommas]

Dear all!

I have an mysensors ethernet gateway and nodes with nrf24 . I have an openhab2 controller. Could i use the above solution to program my nodes over the air through my current gateway? So i write my sketch on windows arduino and send it through my gateway to the node? Or i have to connect my computer direct to nodes over air?

[gohan]

You can use myscontroller to connect to the ethernet gateway and assign the firmware to upload for each node

[Tommas]

Dear @gohan

Thank you! Superb!

[vikasjee]

@gohan , Thanks for this idea... I am going to try this with a serial gateway instead. Do you perceive a problem? Will this work only with an ethernet gw?

[gohan]

Myscontroller works only as ethernet. Mycontroller should also work with mqtt gateway but I'm not sure about serial.

[vikasjee]

@gohan Ook! Are you talking about installing MysController on Raspberrypi (I think not)? If you are going to run it on Windows and connect to Raspi Ethernet gateway remotely then using the the same option we can remotely connect to a serially connected gateway on Raspberrypi (using a USB port) from MysController running on Windows.

Are there steps somewhere to install MysController on Raspi [some Windows pre-installer running on Debian Linux]? I remember reading some Mysensors posts here a couple of years back(!!!), but cant seem to locate it now...

[gohan]

MyScontroller is a windows application.
MyController is a controller that you can install anywhere. I personally try to avoid the usb gateways because of the limitations.

[Nca78]

@scalz do you have any specific reason why you use avrdudes to burn the fuses and burn bootloader separately, instead of using some board definitions matching the bootloader and using the burn bootloader method for Arduino interface ? I think that method is far more user intuitive for the average MySensors user ?

[scalz]

@Nca78 just old school habit ;) I think in the video both ways are explained. But I'll take a look at the howto to make it simpler, agree.

thx for reminding me!

Using FOTA in myscontroller works only occasionally for me. Sometimes it works fine. But most often I get the following messages and nothing more happens.

The node is a sensebender micro. Gateway is rpi ethernet.

Has anyone experienced something similar? Anyone knows how to solve the problem?

EDIT: Problem solved. Reading this post I now understand that in order to get new fw into the node one has to update the sketch, refresh the repo in MysController and assign it the node.

[gohan]

Once I managed to burn the sensbender micro bootloader to the pro mini, how do I connect the external flash? Just connect it to pins D10 to D13? Is this the correct way of managing the fota in the sketch before the sleep?

[arraWX]

@gohan I recently had some problems with fota and the sensebender sketch you refer to. In this thread @tekka suggested me to enable smart sleep. I used

smartSleep(MEASURE_INTERVAL);

It seems that the smartSleep function has a "built in" MY_SMART_SLEEP_WAIT_DURATION_MS (which defaults to 500 ms). This makes the OTA_WAIT_PERIOD in the sensebender sketch redundant. I deleted it from the sketch.

FOTA now works successfully with my sensebender boards.

[gohan]

I am still in the build phase, I still have to understand how to connect the flash and what to do in the code; also I need to find how to test if everything is is correct

[jkandasa]

@gohan, Yes, MyController works with Serial, Ethernet, and MQTT as well.

[gohan]

@jkandasa I know that but I don't know how to work with the flash chip at the moment

[Luca Calcaterra]

Hi guys! I burned mysbootloader but now rs485 doesn't work.. It's normal situation ? A would like to know if is possible to remote upload firmware via rs485 instead of radio. Thanks! Luca

[gohan]

Mysbootloader doesn't support rs485, you probably need to use the dual optiboot but I haven't heard anyone trying it

[gohan]

I think I managed to get the flash properly wired and using myscontroller I was able to assign a FW and it started to transfer the new FW as soon as the node was available but at the end I get this failure on the node dedug

After this the node goes silent and I have to reset it to get it back. Log parser isn't helping much. Any idea where I can look ?

[gohan]

It must have been a problem with myscontroller since after I tried mycontroller the firmware update was successful. Tomorrow I'll do some more tests. The only issue I found is the upload time that it took 7/8 min to upload using rfm69 433mhz

[gohan]

great, now it is no longer working
I am getting a series of messages like this

and a failed update at the end. I am going to need some help

I ran the GW debug and I am seeing a buch of NACK even if the node is 2 meters away from the GW
