MYSBootloader 1.3.0-beta.3

Try using smartsleep instead of usual sleep

[thm]

Hello, thank you. It basically works with smartSleep. I only have to press the FW update or reboot button several times. After several attempts, the desired action is then executed.

Hello.
First, thanks to everybody developing all the stuff that is here, these are awesome projects and sorry to resurrect an old thread.

Second, i am trying to use the firmware update feature from MYSController, build 3316, with MYSBootloader, 1.3.0-rc1 8MHz, on a barebone atmega 328pu 28dip .
The device is running a simple thermistor sketch and reports happily to my RPi running MySensors ethernet gateway version 2.3.1-alpha(I have tried with version 2.2.0 as well).
I get the "reboot" screen if i choose the firmware after setting the device as a "Board with MYSBootloader" and the device clearly reboots but does not start any firmware download.

And of course, i am running nrf24l01+. Device is batterypowered from an 18650 li-ion, through a mcp1700 LDO 3.3v 250mA. 10uF on the nrf between vcc and gnd.
Device is set to sleep for 60 secs, but is also set to smartsleep for 500ms, as i read somewhere had solved other peoples issues.

Edit: I believe i was being stupid as i first burned the bootloader using arduino as isp and then burned the sketch, alas, erasing bootloader.

@patrikr76 Yes, sounds like you erased MYSBootloader when uploading the sketch via ISP. Please post the MYSController log (starting before you reboot the node until the node is up an running) to verify this assumption.

Hello, everyone. Has anyone ever encountered a problem where after a power surge the device on this bootloader stops working? When I first encountered this, I did some tests. They're confirmed. This applies only to network devices. With the battery there are no such problems at all. So I had to switch to DuaiOptiboot. All stable. I do a bit of home programming :) so I don't think the problem is on my side, simple bugs are excluded.

[tekka]

@berkseo Can you share additional details regarding your tests, ideally including logs that showed the proper function of the bootloader before the surge and after - what tool are you using for OTA updates?

[scalz]

@berkseo

+1 for more details please, regarding hw and the power supply, mcu, fuses too.
weird problem.. it works on batt but not on AC?? how do you replicate these power surge?
if you have AC powered nodes sensible to power surge, transcient, I would add a TVS diode on the dc power supply side, and I would protect signals if needed. adding some filtering does not hurt too, pcb gnd isolation/shielding plane as well.
Because, "even if" there is something related to mys bootloader, it seems also related to surge protection..

Now not many can to share on the subject. We need to reproduce the problem again. OTA through the Majordomo system. But it's not about the update. The device died during a power surge, a feeling that was in the mode of receiving firmware due to the jump. Only re-recording the bootloader helped restore the device.

[berkseo]

@scalz The problem was seen when the voltage surge in the network. It was later reproduced using supercapacitors. Let's try to reproduce the problem as follows: power the unit from 3.3 V, hang the supercapacitor on 1F in parallel and the led on the power through the 1K resistor, wait until the supercapacitor is charged, then wait for the discharge and on the verge of turning off ~ 2V, apply power pulses. I can't debug it right now. Will time will make. Bootloader latest version.
There was a filter and a stabilizer. power surges are in principle excluded

[mafe]

Hello,
can the bootloader also be used on an Atmega32U4? After programming, the Atmega is no longer recognized by the Usb port of the PC. Should programming via the IDE (Arduino, PlatformIO) still be possible or will it only work via MyController?

[mfalkvidd]

@mafe I don't have experience with FOTA, but this part of the documentation might help:

The MySensors master branch does not support upload through ftdi / serial (but the development branch does).

But I don't think MYSBootloader has support for Atmega32U4 at all.

[mafe]

Thanks for your answer!
Sorry, I forgot to mention that I want to do FOTA via an MQTT gateway. Is that working at all right now?

imenticato di dire che voglio fare FOTA tramite un gateway MQTT. Sta f

If I understand OTA well with an MQTT gateway it is not possible. This at least using MYSBootloader

[Mikhail72]

Hello, in one of the devices on mega2560 I want to use MYSBootloader for FOTA. Is this even possible for mega2560?
I changed the MYSBootloader sources for mega2560, the update is on, but it is looping (i.e. it reaches 100% and starts again), I think that the problem is in calculating the CRC of the firmware and I need to fix the static uint16_t calcCRCrom (const uint16_t len) function, but I have lack of knowledge, as I'm not a programmer, but just an amateur. Can someone help or suggest?

P.S. Sorry for my english, it's all google translate

[iguaan]

Hi, have been using myscontroller more than a year now and at some point i couldn't use OTA on devices, all the sensor data is coming in nicely. I don't know if it was due to updated arduino or i messed up something in my doards.txt or something else...
So question is if someone can give me versions/links to working solution?
https://github.com/mysensors/MySensorsBootloaderRF24/tree/development doesn't work.

I'm using ProMini 16Mhz with external oscillator. Arduino is 1.8.13, MySensors 2.2.2,
Myscontroller 1.0.0beta:b3316.

[mfalkvidd]

@iguaan "doesn't work" is a bit too vague for us to help. Could you share a bit information on what you did, what you expected to happen and what happened instead?

[iguaan]

That's the problem, i don't know what exactly happened/caused this. That's why i'm asking for working solutions/versions so i can try to trace back what might be wrong with my setup.

Also now i remembered that i had to renew gateway with esp8266 since previous broke down. I don't know for sure that i had previously ota feature for gateway enabled.

I remember when i got it first working year(s) ago i tried also different bootloaders, fiddled with fuse settings and eventually got it working perfectly, but now (since i've updated arduino) maybe my board settings are incorrect.

[iguaan]

Well found the problem.
I had also changed gw nrf module to NRF24L01+PA+LNA 2.4GHz:
and it seems to be the issue.
Although regular traffic monitoring etc is working ok.
Changed back to usual nrf24l01+ module and updates are working again.
Both variants are ali merchandise.

@iguaan Try to set MY_RF24_PA_LEVEL to RF24_PA_MIN on gateway then use NRF24L01+PA+LNA module - in my case the OTA begin work perfect!

Well finally got time to try it out and it worked like a charm, thank you!
Also no problem with a node that is about 1,5m away from GW.
LOW also worked, but OTA was slow.
