ambiguous overload for 'operator+=' (operand types are 'String' and 'IPAddress') #7

Open remrat opened 5 years ago

remrat commented 5 years ago

Hello, Trying to flash the gateway software onto my new LoRa Go Dock. However, when I compile the code, I get the following error. Any thoughts? We are currently running ArduinoJson 5.13.4

Arduino: 1.8.8 (Windows Store 1.8.19.0) (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Disabled, 4M (no SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Build options changed, rebuilding all C:\Users\T R\Desktop\LoRaGoDOCK-Gateway-master\LoRaGoDOCK-Gateway_wwwServer.ino: In function 'void printIP(IPAddress, char, String&)':

_wwwServer:40:10: error: ambiguous overload for 'operator+=' (operand types are 'String' and 'IPAddress')

I hade the same issue. You need to use v2.4.2 of the esp8266 board lib.

tb4450 commented 5 years ago

Thanks, VictorNine. After switching to v2.4.2 compilation was successful.

ulfraaf commented 5 years ago

Hi "Nice" to find that other have same issue that I have experienced. I did not quite understand what means with "v2.4.2 of the esp8266 board lib", where can I find it and how do I then implement it. I have followed instruction in document: github - SandboxElectronics/LoRaGoDOCK-Gateway READ.md, and come so far that I ended here with this issue. So I hope that someone can help me. /Ulf

I did not quite understand what means with "v2.4.2 of the esp8266 board lib", where can I find it and how do I then implement it.

In the Arduino IDE go to tools > board > board manager, type ESP at the top and change "esp8266 by esp8266 community" version to 2.4.2.
