ESP8266 WiFi gateway port for MySensors

[marceloaqno]

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!!

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...

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));
}

@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?

@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

[alexsh1]

@Eawo the sonoff does not require any GW to work with Domoticz.

[hek]

Yes, @alexsh1 is right. You would normally setup ESP nodes (like the sonoff) to act as a gateway, communicating directly with the controller themselves.

But if you're persistent (or have short wifi range), you can get two ESP nodes to communicate with each other using NRF24/RF69 like @mfalkvidd did recently.

Hi. I have loaded the Sonoff as an Ethernet gateway using the modified sketch in Vera and it recognizes it perfectly. The problem I have is that I dont know how to control the relay with the Vera now. Please help.

@hek @Yveaux I see the blocking issue on the ESP side has been closed... Does this mean we can now use the ESP in high traffic environments? How can we test it, I assume we also need to activate IRQ for the NRF in the ESP gateway code?

[Yveaux]

@Mark-Swift that issue apparently addressed an issue in the vs1053 library, which surfaced because the esp8266 doesn't support interrupts on spi transfers.
The issue was closed because the vs1053 library was modified to support esp8266, unfortunately not because esp interrupt support for spi was implemented...

@Yveaux You're right, should have read more before jumping to conclusions :(

Damn, I thought I could finally dump my serial gateway!

[ahmedadelhosni]

Is it normal to use GPIO15 ? Isn't it used for booting mode ?

[mfalkvidd]

@ahmedadelhosni where is gpio15 used? (This is a very long thread so finding it without your help isn't easy)
