Compile errors with PlatformIO

[tk5ep]

HI, I'm trying to compile the ESP-1ch-Gateway with PlatformIO, but I get these errors :

C:/Users/Admin/Documents/PlatformIO/Projects/ESP-1ch-Gateway-master/src/_txRx.ino:309:44: error: call of overloaded 'abs(uint32_t)' is ambiguous

*** [.pio\build\Gateway_38\src\ESP-sc-gway.ino.cpp.o] Error 1

Does anyone has a solution?

Also, I would like to use a NodeMCU v3 board. Any luck to succeed ?

Thanks, Patrick.

I've downloaded code as zip, compiled (on Windows) and it succeeds. Did you change anything? Using latest code?

[tk5ep]

Hi Miha,

Thanks for responding. I've downloaded the version which is on the main page and haven't changed anything at all for a first test.

I use VSC 1.81.0 on Windows 10.

[MihaMarkic]

By your error log it might be a problem with xtensa stuff. I'm using these board settings, try using them and see if it compiles

platform = espressif32
board = ttgo-lora32-v1
framework = arduino

[tk5ep]

Same results.

I tried to compile with the Arduino IDE. I also get a lot of errors despite all my corrections (libraries, wrong declarations)

I'm close to give up and I'm still looking for a working SCPF to make tests on the 433 MHz band.

[MihaMarkic]

You have more libraries than me, odd, here are my (under lib directory)

aes ArduinoJson esp32-http-update ESP8266_and_ESP32_Oled_Driver_for_SSD1306_display ESP8266_Oled_Driver_for_SSD1306_display gBase64 LoRaCode Streaming Time TinyGPSPlus-1.0.2b WiFiManager-development

and here is my only dependency declared in platformio.ini file

lib_deps =
  # RECOMMENDED
  # Accept new functionality in a backwards compatible manner and patches
  sandeepmistry/LoRa @ ^0.8.0

Try deleting your lib directory for starters and use my board configuration, I assume it will be recreated with just necessary libraries.

[tk5ep]

Thanks for taking the time to try to help me. Removing the libraries didn't help. I can't imagine how VSC can put the right libraries if there are no libs deps declared. I'm not a PlatformIO specialist, so I'm a bit stucked.

With an empty lib folder, I compiled several times and resolved the library errors, one by one. I ad to change some library names in the main sketch and load newer library versions until it worked.

Now it compiles further but I have this error : *** [.pio\build\TK5EP\firmware.elf] Implicit dependencyC:\Users\Admin.platformio\platforms\espressif32\builder\lib_deps' not found, needed by target .pio\build\TK5EP\firmware.elf'.

Can you check if you have the same libs and versions ? (except for the WiFImanager I ihad to change, it didn't find a function in the original one)

Thanks,

[tk5ep]

I managed to succeed to compile for a TTGO board.

But as soon as I change some settings in the 2 config files, it's going mad ! Dependency problems, some errors, etc...

Did you succeed to flash a TTGO board and make a gateway working ?

If yes, can you send me your confignode.h and configGway.h ?

But I think, I will give up. :-(

[tk5ep]

SUCCESS ! I managed to compile and make the gateway work, after a lot of testing and tweaking. I had to scratch my head how to configure the whole stuff (WiFi settings, gateway ID, etc...)

I use a TTGO T-beam 1.21 module.

It needed some time, but it finally works. I had to use the original config files and made only a very few adjustements.

The gateway reports to our local Chirpstark server.

But for the moment I can't decode my sensor board made with a demo sender software on an Arduino and sandeepmistry library. Maybe a pin configuration ?

Does someone have a sketch for Arduino that works to send LoRaWan packets ?

Thanks,

[Bobkatze]

Can you share your Projectfile? I have been trying to compile it for the T-Beam V1.1, and have fixed some errors, but still cant compile and progress further with my current one. EDIT: Nevermind, I successfully compiled it under arduino and got it running. Did you manage to make the OLED display show information? Mine just remains empty.

[tk5ep]

Hi Bob,

Glad to hear that you managed to compile successfully. Unfortunately, it looks like there is no support for this outdated package.

Yes, OLED works perfectly. I understand you have a T-beam I have a T3. Did you correctly set the OLED type in configGway.h ? # define _OLED 1 as to be adjusted to the Oled type.

What band and frequency will you use ?

I can see my Gway receives packets, and forward them. But I can't see them on the Chirpstack server. I need to be a bit more skilled in that.

Also decoding SF12 doesn't work, SF7 works perfectly.

My solution for the same compilation problem was in _txRx.ino:316:

if (abs((int32_t)(freqs[gwayConfig.ch].dwnFreq - fff)) < 100000) {

So, just add a typecast to int32_t.

HTH, regards Klaus
