Having used the Microchip RN42 BT 2.1 module for some time, I thought it would be simple to migrate to Low Energy 4.1 using the Microchip RN4020. Not so!
Found out that I know nothing and need a good steer from learned forum members.
I've got a BLE2 click board from Mikroelektronika running on an Easy AVRv7 board with an ATMEGA16 mounted so the test environment is sorted and I can monitor
the traffic to the UART port which is OK.
My problem is understanding how to get a BLE scanner to communicate with the RN4020.
Any advice on a good reference book on Low Energy BT would be a great start.
Also any advice on how to tackle talking to a portable device like a scanner would be greatly appreciated.
