These days I am in Shenzhen city, China.. This is the world capital of technology. seriously.. I am already making my wish.. Blutooth to RF data transceiver module. The factory is making 3 samples to my order. This is useful because its small size allow it to attach it to the phone and start sending data by RF instead of bt.. With a range of 2km it is cool gadget.
Yes it's the same as lora.. Chn copy.. with TTL input to directly connect to HC-6 Bluetooth module. The receiver has RS485 output for easy interface to Arduino and other controllers.
Sounds interesting. I have worked with HopeRf modules and would like to test the ones from Laird (single module BT +Lora), but they are quite expensive in my opinion.
What I like in the thing I am doing is that, it's open source hardware.. Exact same HC6 connected to the general purpose 433 RF module.. So you are not tied to any properiatory technology.. It's in the $10 vicinity.
