internet connected switch (EasyIoT Cloud MQTT API)

whogarden wrote: Hello,
I try to use the tuto : internet connected switch (EasyIoT Cloud MQTT API),
I installed the files linked in the tuto : " github.com/iot-playground/EasyIoT-Cloud/...r/libraries/esp-mqtt ".
...
With Arduino IDE I have a lot of errors like :
undefined reference to `MQTT_InitConnection'
undefined reference to `MQTT_InitClient'
an so one .....
Sure, something is missing, but what? Where? (in MQTT libraries?)
Can you help me I don't know what to do.
Thank you.

I deleted and reinstalled the libraries and now the upload is OK, but it doesn't work, I have the same problems as the 5 comments of the tuto page.
With the debug, I have no message in serial
I paid attention to
Change lines 7, 8, 10, 11 and 15 with the good values...
The wifi is activated (seen by android tablet)
and is seen in the home network 192.168.1.26
The module is powered with a 3.3V 3A alim.
There is a 2200uF on the 3.3V.
I tried with an esp 01 and an esp12 nothing works.
What can I do now please?

I have seen that the pb desappears if I comment (in debug mode) the 2 lines with "BUILTIN_LED".
But, now, on the serial, I only have :
Connecting to Livebox-3262
............
WiFi connected
IP address:
192.168.1.25
Connecting to MQTT server
MQTT client id:18:fe:34:e6:7e:3b-c2
connected to MQTT server
One time I could see "/Db/5641f8b5cf045c757f7e62fa/5/Sensor.Parameter1: 1"
But I put 4 in the line "MQTT myMqtt" because I've #4 on the Android tablet.
It was after some modules deleted. But they are always back , I have now 3 modules (#3, #4 and #5).
I just need one to test now, so can you delete them (#3, #4 and #5) please.
Will it be possible to use more than one switch?
Thanks.
