Respected Sir,

I am compiling for ESP32 Arduino Client and I get following error. I have uncommented
#define DLMS_IGNORE_SERVER from gxignore.h. Arduino IDE Version 1.8.12

Arduino: 1.8.12 (Windows 10), Board: "ESP32 Dev Module, Disabled, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, None"

Kindly advise how to resolve.
Thanks and Regards

Respected Sir,

Could you please guide on this issue.

Hi,

We have tried to repeat your problem, but we can build this without problems.
Select "File" and "Preferences". Then let me know what "Additional Boards Manager URLs" you are using?

BR,
Mikko

Respected Sir

Thank you for your response.
I installed the ESP32 for Arduino using the official procedure provided by expressif
https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide…

The Additional Board URL is one of STM32

Further I installed new version of Arduino IDE 1.8 and selected the board Mega2560. I got no errors.
Then I selected ESP32 board whose url was https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/pack…

I selected the Board DOIT ESP32 DevKit
Compilation gave following error. Kindly advise.

Hi,

This is changed. Get the latest version and let me know if you have problems.

Sir,

I got the latest code and yes that old error is gone. But this new error has come in
File Preferences URL

Error compiling for board DOIT ESP32 DEVKIT V1.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Hi,

Another library is using the same function name (bb_init). There is no easy workaround for this because we can't change the name of the bb_init.

I need to think about this.

BR,
Mikko

Thank you sir.

Thank you sir.
I think it would be difficult for you to change the whole repository. But at the same time it makes a popular ESP32 unusable. I will wait for your solution.
ESP32 also has a ESP-IDF Freertos. Can you suggest me minimum C code files needed which can be compiled for meter reading application. ? If feasible I could try that.

Thanks and Regards
Ajit

Hi,

Changing this to the repository is not the problem. Problem is that we have a lot of clients who are using this and we can't rename it. I'm thinking if we can use define for ESP32.

Open gxignore.h and un-commnet all features that you don't need. DLMS is not an easy protocol and you can't just take a few files.

BR,
Mikko

Thank You sir,

I will wait for the changes.
May I request you to keep me posted soon the changes are effected.
Warm Regards
Ajit

Hi,

Get the latest version. This in now changed.
Arduino DOIT ESP32 uses bb_init. bb_Init is used instead in DOIT ESP32.

BR,

Mikko

ThankYou Sir,

This worked well.

hello technoshell, can i get…

hello technoshell, can i get your help on the step by step procedure on how you worked with arduino and dlms communication, my first question would be what your project is all about, i am working on a project to build a smart meter using arduino as my microcontroller and communicate with it using gxdlmsdirector, but i cant seem to understand most of the technical terms on this website
