MYSBootloader 1.3.0-beta.3
-
@slt1 Thanks for the report. I tested on two different nodes. Controller: MyController.org. Gateway MQTT(ESP8266), Radio: NRF24L01+
- 8 MHz internal crystal on the noisy environment: for 47K hex file takes 6 minutes and 42 seconds
- 16 MHz external crystal on clean environment: for 26K hex file takes 36 seconds
Bootloaders I use: https://forum.mysensors.org/uploads/files/1475275020003-mysbootloader_v13pre2.zip
Initial days I face coverage problem with NRF24L01+. I changed my antenna as per this specification, from this point I see notable improvement on coverage.
@jkandasa I tried the modified antenna out and also removed the adapter board for the nrf and soldered a header in close to the arduino pro mini to insert the nrf24l01. And after doing, with all other sensor nodes turned off I can now get around 5 seconds for blink, about 30 seconds for TimeReporter and about 60 seconds for the 60kb custom sketch.
So thank you for the tip on antenna mod. That does help. The major issue I think though was the adapter board for the nrf24l01 - for some reason that was causing lots of pauses in the OTA updates.The tests were all using MYSController - the windows app.
I am having a few strange issues MYController.org. It appears to be getting stuck when doing a few updates in a row and also I can't seem to roll back to a previous version.

@gohan The manufacturer on the bottom of the board says robotdyn.com - lookinf at their website this is the exact one : http://robotdyn.com/catalog/adaptors/socket_adapter_for_nrf24l01_with_regulator_3_3v/
-
I use these adaptor boards, I presumed they worked okay, what is missing @gohan, are the capacitors present on other adapter boards do you know? BTW the robotdyn stuff seems very well made but I've actually found their NRF's to perform very poorly.
-
@gohan The regulator is an AMS1117 on the one I got here. I will try them again as they are useful for prototyping. It was working fine for a regular sensor sending updates, but got into the issues when using OTA and trying to get some decent speed of updates going. I also thought perhaps it was a dud unit - so i tried a few others and all gave same results. So perhaps a bigger capacitor will do the trick.

This is my first post in this forum - so hello everyone! And many kudos for all developers and contributors.
I am on my way of building distributed sensors and actuators system for astroimagers, and would love to have OTA firmware update possibility. I use nR24L01 radio and each node will be based on Atmega328 working at internal 8MHz and 3V, and have two questions:- which bootlader hex should I write?
- does MYSbootloader support programming via serial? I tried several hex files with several fuses combinations and never succeeded to program Atmega328P via serial :(

Ok, what I've done so far according to https://www.mysensors.org/about/ota:
- connected USBasp to Arduino Pro Mini and set fuses to 16MHz external oscillator (using AVRDUDESS)
- then tried to upload MYSbootlader using Arduino IDE (versions 1.6.11 and 1.8.1) but it failed with some "cannot set sck period"
- so I uploaded bootloader with AVRDUDESS
Question is - at this stage should I be able to program Arduino Pro Mini with serial programmer, or now it can be done only using OTA? Because I am not able to do it with serial programmer and Arduino IDE.
Burning bootloader with AVRDUDESS works fine because I changed it many times from original to MYSbootlader, also programming Arduino with precompiled sketch works fine.
I will describe my project little bit later, when I will have more nodes working :) Currently I am on stepper motor controller node.

@jolo yes, MYSbootlader supports only ota. No serial.
I have updated the ota page to mention the lack of serial.
@mfalkvidd actually looking at the code of mysbootloder, it does support STK500 protocol. I haven't test if it really works...maybe it doesn't.

@mfalkvidd The most recent MYSBootloader supports OTA and serial uploads via STK500, see here: https://github.com/mysensors/MySensorsBootloaderRF24/tree/development

@tekka thanks.
I did look there, but didn't find anything that I understood was related to serial. I also looked at the list of commit messages but none of them mentions anything about added support.Anyway, thanks for clarifying. I'll update the ota page again.

Many thanks for help - today I made it work :) Here are my steps that worked for me:
- I used MYSController 1.0.0 beta, took bootloader MYSBootloaderV13pre.hex and uploaded to Arduino Mini Pro with AVRDUDESS and USBasp programmer
- then uploaded serial gateway sketch to another Mini Pro
- attached nR24L01+ radios to both
- connected MYSController, configured serial connection and all just started to work
- then uploaded simple DHT sketch, edited csv file in MYSController and selected it for OTA FW update
After less than minute new FW was already at the node and it started to send data. I am very happy :) I played with Arduino projects for several years, but this stuff you have made is absolutely amazing! Now time for some real nodes - first one will be stepper controller for telescope focuser.
-
It still works fine - however I have one more question, maybe stupid :) About RF channels. I use nR24L01+ radios at default channel 76, however for final solution I would like to switch to some higher freq. Does precompiled bootlader work only at this default channel 76? So if I would like to switch to channel 101 I need to compile bootloader with this setting? Or there is some magic behind that makes it work some other way?
