ESP8266 OTA and Arduino IDE What Am I Missing?

GardenShedDev

@BearWithBeard Thank you for having a look into this!!!

I retried minus the yield() - still doesnt work (its the only combination I havent actually tried upto this point!!) - also yes I can ping the device on the network.

I am running Arduino IDE 1.8.13, I have tried restarting, gone to another laptop (windows) as I run OSX, waited a minute, an hour, 3 hours, no joy with the MYS OTA.

When I use the Arduino OTA everything works as it should, the board shows up in the Ports menu straight away.

Through process of elimination its not a HW related problem (ESP or network), but I do definitley think its a SW problem specific to the MYS library.

This has got me thinking a little, I am going to recompile the sketch using the windows laptop to see if this works - my thinking being there may be a library problem on the mac.

Im going to swerve platformio at the moment but it does look intriguing so im going have a look at this in down time over the next few weeks :)

@GardenShedDev just to check, when the gateway is running, it prints the normal MySensors debug info (messages received and sent), but none of the serial prints registered in setup() are triggered?

@mfalkvidd heres a typical output from the gateway serial. Just did a power cycle and captured the startup and then a couple of transactions at the end;

Just to make doubly sure I addded

To me it looks like you are not connected to the network at all based on the last output.
Did you check this?

GardenShedDev

Yes it is connected, the psu bumps a little and then settles down when initially turned on (despite having extra capacitors strapped to the NRF and ESP) and then starts communicating as expected. I suspect its to do with the length of the leads and the thickness connecting the nrf to the esp, I either need to shorten the leads or put thicker ones in place to compensate for the v drop.

Funny thing is tthe HW 'as' configured works for Arduino OTA but not the MYS OTA?!?!

mfalkvidd

@GardenShedDev how about disabling

#define MY_RADIO_RF24

to see if OTA + MySensors - NRF24 works?

If the problem is power related, nrf24 is the largest power consumer.

BearWithBeard

@GardenShedDev ArduinoOTA should not be confused with the MySensors-specific OTA features to upload firmware via other transports (like NRF24) to remote nodes. There's nothing special about ArduinoOTA when used alongside MySensors. As far as I know, MySensors doesn't mess with it at all. It's completely separate.

Here's a dependency graph from a basic ESP8266-GW sketch with ArduinoOTA:

|-- <MySensors> 2.3.2
|   |-- <Wire> 1.0
|   |-- <SPI> 1.0
|   |-- <EEPROM> 1.0
|   |-- <ESP8266WiFi> 1.0
|   |-- <ESP8266SdFat> 1.1.0
|   |   |-- <SPI> 1.0
|-- <ArduinoOTA> 1.0
|   |-- <ESP8266WiFi> 1.0
|   |-- <ESP8266mDNS> 1.2
|   |   |-- <ESP8266WiFi> 1.0

That being said, I've now tried to replicate this issue again with different ESP8266 cores from version 2.5.0 to 2.7.4 and MySensors from 2.3.0 to 2.3.2. It's always the same behaviour: It may take the ArduinoIDE a minute, a restart of the IDE or an hardware reset of the NodeMCU to list the device. But in the end, it always connects, uploads and executes the new sketch properly. In any case, I can always OTA-upload manually as soon as the ESP is online, no matter if the ArduinoIDE lists it or not.

I'm not sure what's causing this issue for you, but I honestly doubt that the MySensors framework is the culprit.

The static IP configuration from your earlier attempts might still be retained. Try adding this to the beginning of setup() for test purposes:

WiFi.disconnect(true);
delay(1000);
WiFi.begin(MY_WIFI_SSID, MY_WIFI_PASSWORD);
WiFi.config(0u, 0u, 0u);

Or clear the whole flash, in case some other WiFi related stuff may still be stored (Tools > Erase Flash > All Flash Contents).

You may also try OTA-uploading a sketch a different way. From a terminal, this should look like this:

path/to/python3 path/to/espota.py -i 192.168.esp.ip -p 8266 -f path/to/sketch-binary.ino.bin

On Windows, you should be able to find the ArduinoIDE-managed python3 in %localappdata%\Arduino15\packages\esp8266\tools\python3\xxx-version-string/python3 and espota in %localappdata%\Arduino15\packages\esp8266\hardware\esp8266\xxx-version-string/tools/espota.py. On Linux and macOS, that should be ~/.arduino15/... or ~/Library/Arduino15/...

The ArduinoIDE saves binaries to some temp directory by default, I think, but you can use Sketch > Export Compiled Binary to save it in the same folder as the sketch.

@BearWithBeard @mfalkvidd

Some good news and progress!!

Seems like the NRF power consumption was indeed the culprit. Disabling the NRF in the software didnt do the trick, however when I disconected the power to the module and restarted, after about 10 minutes it appeared in the IDE Network Ports section and I can upload sketches over OTA.

As a result I have trimmed down the connector leads to 2 inches, which still works in my enclosure, added another 10uF cap across the ESP regulator and replaced the one strapped across the NRF module. I have lost all the 'bounces' in the debug log from the ESP and the OTA is available straight away every time the board is power cycled. I wont know for sure until I can get my scope out of storage but I suspect that the original 10uF Cap had become more of a resistor than a capacitor with use over the last 2 years - one for the list during down time over xmas :)

So while I have a fix, the elephant in the room is why did the Arduino OTA sketch work and why did the MYS OTA sketch not work?!?!?!

Does the MYS OTA sketch handle power/ comms/ timing in a different way to the Arduino OTA sketch which could cause this problem? or, Is it a timing thing and by this I mean is it a race condition on the power between the ESP core working through its startup and the sketch and the NRF turning on and the causing the power to bounce?

mfalkvidd

Nice work @GardenShedDev

About why this happens: creating different scenarios and doing lots and lots of testing is probably the only way to find out. Or connect the scope (or something like Otii) and try to match voltage/current event to parts of code.

GardenShedDev

@mfalkvidd - your response got me thinking about my question some more - the effort required to diagnose/ rework would for little gain, i am thinking its simpler to rework the psu and seperate the NRF from the ESP - its likley that the ESP regulator is only spec'd to power the ESP and not a lot else - lets face it we are not dealing with miltary grade components here lol :)

Thanks for the help and support!
