Hi friends,
I just bought 3 Heltec Wireless Stick Live V3 (HTIT-WSL_V3) from https://www.aliexpress.com/item/1005004984658496.html.
I want to install and run example sketch pingpong.ino.
(https://github.com/HelTecAutomation/Heltec_ESP32/tree/master/examples/LoRaBasic/pingpong)
But, I am getting this compiler error:
./pingpong.ino:69: undefined reference to `_ZN8McuClass5beginEhh’
collect2: error: ld returned 1 exit status
exit status 1
Error compiling for board Wireless Stick Lite(V3).
line 69: Mcu.begin(HELTEC_BOARD,SLOW_CLK_TPYE);
Development environment:
Ubuntu 24.04
Arduino: 1.8.19
Any advice and suggestions will be appreciated.
Kemal.
