Hi, there, I did a big update in the last few days, and it's already have full region support. Please try the newest library. 
@s0301132 Hi, I had updated the code last few days many times, please use the "git pull" update again. About the sub-band usage, please refer to this document, maybe it...
Did you config a gateway already connected to the TTN? Then, what's the problem now?
Let's talk here: [http://community.heltec.cn/t/lora-wns-heltec-modules-wifi-lora-32-868mhz-for-gas-monitoring-mq136-sensors/1392/2](http://community.heltec.cn/t/lora-wns-heltec-modules-wifi-lora-32-868mhz-for-gas-monitoring-mq136-sensors/1392/2)
Did you give a RST single on GPIO16?
Seems your problem is because you didn't install the framework correctly. Please refer to this document: [https://docs.heltec.cn/#/en/user_manual/how_to_install_esp8266_Arduino](https://docs.heltec.cn/#/en/user_manual/how_to_install_esp8266_Arduino)
