Thanks! That is what I was looking for!

Well, problem solved. I removed the ESP8266 harware libs and reinstalled them now using the Boards Manager. Then it works fine. But a manual download of the ESP8266 hardware lib causes all these comilation errors.

Thanks.

Have the same problem and it is solved indeed by uing an ESP8266 Arduino version prior to 3.0.0. Thanks for the tip! But that is a temp solution only. Anyone an idea when a new version of MySensors will be there?

I found out that the same errors occur if i load mySensor library 2.1 or 2.0. It is not related to 2.2 version of mySensor.
So what goes wrong? For this matter, I downloaded the ESP8266 hardware library again, and ran
python get.py

So the ESP8266 harware lib is the newest. And then still it generates all those error, again and again.

I certainly did.
When i compile the following Sketch, I do get the first compile error mentioned above:

#define ESP8266

#define MY_BAUD_RATE 9600
#define MY_GATEWAY_ESP8266
#define MY_ESP8266_SSID "xxx"
#define MY_ESP8266_PASSWORD "xxx"
#define MY_PORT 5003      
#define MY_GATEWAY_MAX_CLIENTS 2

#include <ESP8266WiFi.h>
#include <ESP8266mDNS.h>
#include <MySensors.h>

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

What is wrong with this sketch (besides that it does nothing)?

Hi all,

I must be crazy, but I have a strange but big problem with version 2.2 of mySensor. I use it on esp8266 (Wemos), and with a previous version my program compiled without a problem. I upgraded to mySensor 2.2 and 2 problem arised. First my compilation first resulted in:

So I changed file MyMainESP8266.cpp and replace int for uint32_t. When I then compile the Sketch, it comes with the following load of errors:

What do i do wrong???

Thanks for any help,
Dirk Jan

Thanks! That is what I was looking for!

Hi, I start using MySensor. I red that MySensor also stores data in EEPROM, to have it available after the device has rebooted (like the state of a relais). What address locations does it need/use? This is relevant, because I use EEPROM in my Sketch as well.

Regards, DJ
