💬 FOTA (Wireless Programming)

[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

[manutremo]

My FOTA updates take 3-4 minutes at normal speed. I think you are having some different communication issue.

[dakipro]

Is it possible to use this bootloader with arduino Mega boards (mega 2560)?
What should be set in boards.txt then?

[gohan]

@dakipro as a node or as gateway? Anyway I don't think it is supported

[dakipro]

as a node, I want to build one ambitious notification node with a bunch of functionality, Due to number of interrupts i would like to have (and total sensors as well) it would have to be a mega board.

It would be physically located in other part of the house, so wireless programming would be awesome if possible :)

[gohan]

May I ask why do you need that many interrupts?

[karlheinz2000]

DualOptiboot: if you do your own board layout, always keep the CS signal of the external flash at pin D8. You can change the pin number in your sketch, but not for the bootloader It is hard coded in the bootloader!
In this case the uploaded firmware is written to external flash by the sketch, but the bootloader can not read it and not write it to internal flash. Firmware will never get updated. Took me some time to find out...

[dakipro]

@gohan never saw your reply sorry.
I am assuming I need more then two interrupts as I would like to have several buttons and sensors to the node. I am building a "information" node from an old lamp that will have a pir, lcd, temp, rgb led. Also a proximity and few others like microphone from the secret knock example, air quality, buzzer.
I guess I could get away with checking on sensor/buttons state on each cycle since it is not a battery powered sensor, but I assume I will need more memory anyway for all the libs.

(I know that perhaps the raspberry is better for this task, but... would like to push arduino and myself a bit more :) )

[gohan]

Since it's not a battery node, you can use pretty much anything you want. If you want to give it a shot, there is also a 3.3v pro mini with a Mega 2560 chip that should give you plenty of room and power for all the libraries you want.

[Spanners]

Can I add a +1 for Mega2560 support in the MYSBootloader please?

I have 3 Mega based nodes (Irrigation and Pool Controllers). 2 of which are in spider infested, confined spaces in the garden. OTA would be a joy.

[dakipro]

@gohan yes, but can it FOTA? :)
Never saw pro mini with mega chips btw (or didn't know the difference), do you have any links maybe?
