I purchased 2 LoRo modules a while back (HopeRF RFM95W)... Setup on 2 Arduino Nano's was quite simple , with the RadioHead library.
So once both nano's are programmed as client/server respectively....it all works very well. The rage is very impressive compared to the other less powered trancievers I've tried.
What I do like (enjoy) about my $5 China transcievers is their ease of use. The cheapo thanscievers basicaly use 3 or 4 connection (+ gnd, rx/tx)...and you're in business...
There is no encryption of packet transfers of course which is a limitation....but EASY is the key word when working with the arduinos!
My issue is about trying to send simple information over the trancievers such as...clocktime.
The RadioHead example looks like this>
uint8_t data = "Hello World!"; rf95.send(data, sizeof(data));
I realise that we in the Arduino world are at the forefront of developement with LoRa (smiling!)... But it would be nice if a programming guru solved this simple problem for us NEWBs, with a more simple example to print out something other than HELLO WORLD..
BTW,...my client nano is connected with a DS3231 rtc..
Cheers to all... Seems like the future is in connected hardware...which includes LoRa...
She better be worth it,...cause she ain't easy...;-)
