ESP8266 WiFi gateway port for MySensors

[Mark Swift]

@Yveaux I'll sure give it a shot when time allows, most likely tomorrow... I've actually worked around the issue by using a regedit hack on my Windows server to remove the 200ms TCP delay. I also fried a Node MCU tonight due to frustration and not concentrating!

Thanks for the efforts, sounds a great solution :)

BTW, I figured out my main issue was trying to put the nRF24l01+PA+LNA and ESP in a small project box, I guess that also causes issues, especially with the crappy cheap unshielded PA modules (I'm awaiting a proper shielded version).

@robosensor also...

[Mark Swift]

@Yveaux Is there a way I can track dropped messages?

[Yveaux]

@Mark-Swift my queueing code counts how many messages could not be stored due to the queue being full, and therefore got lost. If the radio drops messages because it's FIFO is full we won't know...

[Mark Swift]

@Yveaux I just tried to compile it and get the following error:

In file included from /Users/markswift/Documents/Arduino/libraries/MySensors/core/MyTransportNRF24.cpp:23:0,

#include <util/atomic.h>

[Yveaux]

@Mark-Swift Sorry, my bad. This is AVR only code... Have to look for the ESP equivalent...

[Yveaux]

This util/atomic.h is an easy fix, but then the next error occurs: current ESP8266 Arduino port (even tried upto 2.2.0) does not support SPI access from within interrupts (SPI.usingInterrupt is not supported.
See https://github.com/esp8266/Arduino/issues/1943.
This means I cannot reliably get the message data from the nRF from within an interrupt on ESP8266, using the regular Arduino SPI library.
Have to think if there's another solution (or push this issue to be solved ;-) )
To be continued...

[Mark Swift]

nightmare!

Let me know how you get on...

[signal15]

Is anyone having luck running the ESP without problems at all? I'm on 1.5 and it's my first gateway, and I cannot get sensors to include. Should I try the development branch? Or, should I build a different gateway altogether? I just need something that works at this point.

[alexsh1]

Let me reiterate what @signal15 asked - did anyone successfully have esp8266 running as the GW on 2.0b? I have just acquired Wemos mini and would like to try it

[Anduril]

@alexsh1 @signal15 I can confirm that the ESP gateway is working fine and stable. I even enabled the ESP OTA update function and that's working fine too.

[signal15]

@Anduril

Can you point me to documentation on how the OTA update stuff works and what the capabilities are?

[Anduril]

@signal15 well there is a doc about OTA here. I discussed this topic with tekka, who is the author of the GatewayESP8266OTA example in the mysensors lib here.
It took me some time to get this working, but now I can upload new firmware to my ESP using wifi. Only drawback is that is seems to be not compatible with the mqtt version of the gateway. At least I was not able to get this working and stopped on that.
If you have further questions, don't hesitate to ask.

I recently built a mysensors node with esp8266 where I needed many I/O pins which made me realize the possibility of using the pin RX (http://www.forward.com.au/pfod/ESP8266/GPIOpins/ESP8266_01_pin_magic.html).
Initializing the serial with:

Serial.begin(MY_BAUD_RATE, SERIAL_8N1, SERIAL_TX_ONLY, 1);

allows to use RX pin for I/O.

So I was wondering if it would be useful to add a way in which the serial port can be initialized:

#define MY_SERIAL_MODE SERIAL_TX_ONLY
#define MY_SERIAL_MODE SERIAL_RX_ONLY
#define MY_SERIAL_MODE SERIAL_FULL   (default)

github.com/marceloaqno/MySensors/commit/687fecc6b4abb782eae8e1abb3b07016bfeac291

Also, to use the esp8266 analog pin, I had to comment the line:

ADC_MODE(ADC_VCC);

from MyHwESP8266.cpp.
Is there another way to use analog readings without messing the code?

Excellent port by the way, I have been using here and it works great!!

[Mark Swift]

Was the blocking code issue ever resolved @Yveaux ?

[Yveaux]

@Mark-Swift no, still open at Esp side, and I couldn't think of a clean way working around it...

[gloob]

I have an ESP using as a gateway and want to send some sensor information each 5 minutes to the controller.

Is it possible to use the wait command in the "loop"?

void loop() 
{
  wait(unsigned long ms);
  statusCounter += 1;
  send(msg.set(statusCounter));
}

[mfalkvidd]

@gloob yes

[gloob]

Thanks for the answer. So all incoming or outgoing messages of the gateway will be processed in the background, while the "wait" command is active?

[hek]

@gloob Yes

Hey

Im not really getting it is this a gateway for mysensors nodes or for mtqq Nodes with esp stuff? I dont really getting it. Do you need a esp8266 wifi gateway to get a wireless gateway for mysensors stuff or is like. Mysensors gateway ---> Esp8266 gateway --- Esp8266 node.

Sorry i dont really understand but im intressted in buying 8-10 sonoff for my window lamps, and i want them to work with domoticz :D
