How to select 868 or 915 mhz frequency of E220-900T22D?

[George]

Hi

I’m studying EBYTE modules (thanks Renzo for the tutorials).

How do I select the 868 or 915 mhz frequency of the E220-900T22D?
I live in Brazil and here the frequency used in Lora is 915mhz.

Thank you so much

Hi George,
I think you can use 915, but you can refer to the global table that I shared here

LoRaWAN LoRa Frequency Plans and Regulations by Country

I just identified that it is possible to choose the frequency using #define.

I saw this on github: https://github.com/xreef/EByte_LoRa_E22_Series_Library

# define  FREQUENCY_433 
# define  FREQUENCY_170 
# define  FREQUENCY_470 
# define  FREQUENCY_868 
# define  FREQUENCY_915

Thank you Renzo

Yes, it’s correctly, you can refer the article
Ebyte LoRa E22 device for Arduino, esp32 or esp8266: library – 2
