ESP8266 WiFi gateway port for MySensors

[Pseudomizer]

I tried my Home Wifi and my Cell Hotspot. The crashes occur on both wifi networks. :-(

[ridge]

@Pseudomizer , Is the esp8266 on a breadboard or is it part of a commercial product like HUZZAH or nodemcu ? I ask because the esp devices can reset themselves from a brownout condition during the WiFi transmit if the power supply circuit is not up to handling the momentary 'high current draw' requirements of the radio. From reading www.esp8266.com, breadboard circuits have caused many hours of troubleshooting enjoyment with the esp8266 parts.

I replace the battery packs on these with 2 Amp cell phone charger power supplies. I have 8 under power 24/7 for months with no problems. They are available from multiple vendors.

I followed the instructions exactly as shown here and I purchased that exact equipment.

http://www.mysensors.org/build/esp8266_gateway

I even powered the NRF24L01+ from a different power source just to make sure that power fluctuation is not the issue but it didn't make any difference.

I even tried transfer rates 115k, 57k and 9600 Baud but none of that made any difference either.

I also downloaded the flash eeprom ino program to clear all the data but again, no difference.

[Pseudomizer]

I even reflashed the ESP8266 with those instructions and then loaded the mysensors ino but still the same outcome. :-(

@Pseudomizer did you make any changes to the gateway sketch out the MySensors library/config?
Could you post the output of the gateway just before the crash occurs (it might give an indication of where this crash occurs)

[Pseudomizer]

The only changes to the sketch are the SSID, the pass and the debug line

Serial.setDebugOutput(true);

as instructed. No other changes were made.

Here the the debug output....you will see multiple resets in a row based on the internal watchdog timer.

Triple-check your radio wiring.

[Yveaux]

@hek said:

Triple-check your radio wiring.

Or try with a different radio. The crash seems to happen in the radio init part.

[Pseudomizer]

I just replaced the NRF with a new NRF and then again as I have 4 total. With every single one the same error.

The wiring matches exactly the picture from mysensors.

This is driving me crazy...

Hi, I tried the bridge with a rfm69hw module. It starts all well but does not receive any information. Neither shows startup information module .
Where to put the DIO0 . I tried on several pins ( changing IRQ number) but no thoughts about doing anything.

[Yveaux]

@miguelingles I didn't test with a rfm69hw module and I'm not aware of anybody else testing with this setup.
Probably you have to test step by step what work and what not.
Start with the radio initialization to see if the communication is ok, and go on from there.

[Yveaux]

@Pseudomizer past few days @hek and I have been working on better diagnosis for the ESP8266 regarding radio communication failures.
Please try if the version of MySensors development helps in diagnosing your problems.
Make sure to uncomment the line

//#define MY_DEBUG_VERBOSE

in MyConfig.h and make the same changes to ssid & password as you did before.
This version will dump diagnostics of NRF communications and a full register dump when starting up.
Good luck!

[Pseudomizer]

Thanks a lot. This version provides much more details but at this stage of my learning progress I am not able to understand all those registers where I have to rely on your help guys. I assume that my password is not being exposed here.

@Pseudomizer just had a quick look at your results. Radio config (and this communication) seem to be OK, but it restarts due to watchdog timeout.
Hopefully tonight I can have a better look.

[miguelingles]

when I put the development package I can not compile anything (all gives me error). I tried it with a clean install and nothing.
I think the problem is the IRQ pin DIØØ , if the ESP cpu does not recognize this interruption when the RF module receives data is unable to apply for the request .

The irq pin from the nrf24 stays unconnected, like the build instructions clearly state!

[miguelingles]

but RF69 need irq.

[Yveaux]

@miguelingles didn't know you were talking about rf69... Sorry but I cannot keep track of what everyone is using.

For everyone wondering what serial output during startup of the ESP8266-NRF24 gateway should look like (all captures taken using link development branch from Oct 6, 2015 (hek just merged gateway-refactoring this morning, so output might have slightly changed)) .

WiFi startup comes first after reset, followed by MySensors (nRF24) startup:

• WiFi startup (not using Serial.setDebugOutput(true) )

@Pseudomizer Had a better look at your crashdump.
Your ESP seems to crash with a watchdog timeout when MySensors is setting the datarate (or shortly after that) after nRF24 has been initialized.
Default datarate is RF24_250KBPS.

Some questions, trying to rule things out:

• Do you use this default datarate?
• Could it be that you have an nRF24L01+ clone, which in reality is a nRF24L01 (clone)?
• Did you ever try and succeed to connect these radios to a regular Arduino?
• Are all radio's from the same batch/order?
