multiple definition of `hal_init';

[Raki22]

All good until I get to the 7th step of the README file:

7. Open this project file main/main.ino with the Arduino IDE and upload it to your TTGO T-Beam.

I get this error message:

_/home/rakilachraf/snap/arduino/61/.arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/gcc8_4_0-esp-2021r2/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: /home/rakilachraf/snap/arduino/61/.arduino15/packages/esp32/hardware/esp32/2.0.2/tools/sdk/esp32/lib/libpp.a(hal_mac.o): in function hal_init': (.text.hal_init+0xb4): multiple definition ofhal_init'; libraries/MCCI_LoRaWAN_LMIC_library/hal/hal.cpp.o:/home/rakilachraf/snap/arduino/current/Arduino/libraries/MCCI_LoRaWAN_LMIClibrary/src/hal/hal.cpp:416: first defined here collect2: error: ld returned 1 exit status exit status 1 Error compiling for board T-Beam.

Any help please...thanks in advance.

Add: #define hal_init LMICHAL_init to lmic_project_config.h

That worked thanks, btw the correct setting on board setup for me was 40Mhz + 115200 baud (did not work with default setting 80 + 921600baud )
