Hi !

I’ve new problem… Again ^^ i want add esp8266, i follow this tutorial ESP8266 IoT Control and Monitor Using Arduino, MQTT, and Cayenne - YouTube , and on mine there is this problem. WHen i verify i have this error :

Arduino : 1.8.9 (Windows 10), Carte : “Generic ESP8266 Module, 80 MHz, Flash, Disabled, All SSL ciphers (most compatible), ck, 26 MHz, 40MHz, DOUT (compatible), 512K (no SPIFFS), 2, nonos-sdk 2.2.1 (legacy), v2 Lower Memory, Disabled, None, Only Sketch, 115200”

mydevices_MQTT:5:13: error: invalid conversion from ‘const char*’ to ‘char’ [-fpermissive]

Some one know why ?

try this code Cayenne-MQTT-Arduino/ESP8266.ino at master · myDevicesIoT/Cayenne-MQTT-Arduino · GitHub

3

Ok it compilation work !

I put code on but cayenne find nothing…

I see esp on wifi

4

can you add #define CAYENNE_DEBUG in the code and see what is the error in the serial monitor. Share here the output of the serial monitor.

5

DEBUG is on code, where in find serial monitor ?

can you try adding a new device to cayenne dashboard and get a new MQTT client_id.

9

Wich devices ? i’ve to re add my raspberry ?

If i add new esp i’ve same id

10

on your cayenne dashboard go to:
add new -----> devices/widgets -----> click on arduino -----> copy the MQTT client_id -----> replace it in the code ----> upload the code -----> check serial monitor.

11

ok, like this it work, but i’ve same possibility than i choose esp device ?

12

what do you mean by this?

13

i don’t know, but i have ESP but on my devices list it’s writen arduino and not esp8266 maybe it’s can be problem ?

14

if it is working with arduino, dont do anything. You can delete the old esp device from cayenne dashboard.

15

ok, and one last questions, what’s the widget wich appareid by default ? it say channel 0 with this value : 1061599.00

16

and how i can add new widget on, if i want control relay for example, when i choose on arduino there’s no channel number. I have to write d1 for channel d1 ?

17

In the code, search for this function:

CAYENNE_OUT_DEFAULT()
{
	// Write data to Cayenne here. This example just sends the current uptime in milliseconds on virtual channel 0.
	Cayenne.virtualWrite(0, millis());
	// Some examples of other functions you can use to send data.
	//Cayenne.celsiusWrite(1, 22.0);
	//Cayenne.luxWrite(2, 700);
	//Cayenne.virtualWrite(3, 50, TYPE_PROXIMITY, UNIT_CENTIMETER);
}

this function publishes data (millis()) to cayenne on channel number 0.

Have a look at this topic to get started with cayenne Adding a New Device using MQTT and also go the through entire docs Cayenne Docs

i read all but i don’t find reponse… If i want put relay, i choose arduino, relay and i have to put channel but i can write what i want…

I don’t understand what y have to do for turn on or off pin D5.

I read on code one pin is high or low but wich pin on esp ?!

19

did you check the Step 5 : Adding a Actuator. in the link?

Yap but after button creation i don’t understand what i have to do
