Supported values are 7.8E3, 10.4E3, 15.6E3, 20.8E3, 31.25E3, 41.7E3, 62.5E3, 125E3, and 250E3.

It support also 500€3

@gioreva hows performances at 500e3

gioreva commented 5 years ago

Use the calculator https://github.com/tanupoo/lorawan_toa

And chapter 4 of the datasheet https://www.semtech.com/uploads/documents/DS_SX1276-7-8-9_W_APP_V6.pdf

@gioreva thanks, but this library got some problems, i just used machine to radio waves, and 1024 mhz nearly 700 mhz ... strange..

and another question

what is biggest distance?

sp 12 and 500e3?

gioreva commented 5 years ago

433Mhz, RA-02 in the middle of the houses and plants I did about 5km 10Cm antenna

I didn't understand your problems, I didn't have any.

halukmy commented 5 years ago

the problem is, when we set frequency of 433e6 like something, actually its not give real 433 mhz you should check it..

sooo , can you share your antenna please?

gioreva commented 5 years ago

Yes, is 433 But you can only change frequency at init, not after.

if (!LoRa.begin((long)433050000+((long)Frequenza*25000))) { // initialize ratio at 433 MHz

Already updated with 500Khz https://github.com/sandeepmistry/arduino-LoRa/blob/master/API.md#signal-bandwidth
