ESP8266 WiFi gateway port for MySensors

hek

You could always use ser2net to emulate a serial port connected to the ethernet gateway from you openhab box.

Thank you hek and Yveaux. I thought I had missed something obvious. For the present with openHAB 1.7.1, a small piece of the wireless sensor data super highway of the future is still under construction! In that case I will certainly study the MySensors gateway to MQTT broker examples closely.

Hello guys,

I am having issues with this installation. I got everything up and running but it simply doesn't connect to my WiFi Netgear router at home.

I just enabled my hotspot on my cell phone and the gateway did connect successfully and started the gateway master with IP, etc assigned.

When I try to connect to my home WiFi it just keeps on printing dot dot dot in the serial console.

My Netgear has two networks with 2.4Ghz and 5Ghz. I tried both and none of them worked. They are configured with WPA2-PSK [AES] encryption for the passphrase and the passphrase has one special character included. The SSID is 5 characters long and the passphrase is 22 characters long which shouldn't be an issue.

I don't get any error messages in the serial console and my router doesn't show anything in the logs either like the ESP gateway doesn't even try to connect. I don't know how to troubleshoot this from here.

Any help would be appreciated.

I also have both 5/2.4Ghz on my router.

When ESP connects is seems to prefer 2,4 GHz / n / WPA2 if that helps.

Pseudomizer

This is what I have. 2,4 GHz / n / WPA2 (no TKIP but AES instead so I can go beyond 54Mbit) and it doesn't connect. Just dots coming up.

Yveaux

@Pseudomizer Esp8266 is 2.4ghz only.
You could try adding the following line just after hw_init() in the sketch:

Serial.setDebugOutput(true);

It will dump a lot of ESP WiFi related data, please post the output here. Maybe some will give a hint of what goes wrong.

Pseudomizer

Thanks a lot for this. This helped me troubleshoot the problem and I am surprised why it didn't connect. It couldn't find my SSID name because in the router it is all UPPER case but when I write it on any other machine Windows, Linux, etc to connect to, I always write it lower case with the exception of the first character.

In this case I modified the sketch to have the SSID name all in UPPER case and voila it connected.

Thanks again for the help here. Much appreciated.

I was very happy when it connected but now it is resetting itself constantly with this error message:

wdt reset
load 0x4010f000, len 1264, room 16
tail 0
chksum 0x42
csum 0x42
~ld

Any ideas why?

I missed one line of error code above:

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

@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:

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.
