I live in Hong Kong. I wonder which Frequency or which board/model I need to use for the LoRa communication, please kindly advice will be appreciated.
In Hong Kong you can use frequencies: 920 to 925 MHz
So, you should use the RFM95 with 915 MHz frequency. Even though it says 915 MHz, 919-923MHz is within the range, accordingly to the discussion on this forum:
In this topic they discuss about malaysia, but many things discussed there can also be applied to Hong Kong.
I hope this helps.
Thanks for you prompt reply, I will start to test my ‘Home Automation’ system by using the RFM95 and the frequency that you mentioned accordingly. Again, really thanks.
