RadioLib SX128x BLE Modem Example
|
|
|
|
This example shows how to use BLE modem in SX128x chips.
|
|
RadioLib does not provide BLE protocol support (yet),
|
|
only compatibility with the physical layer.
|
|
|
|
NOTE: The sketch below is just a guide on how to use
|
|
BLE modem, so this code should not be run directly!
|
|
Instead, modify the other examples to use BLE
|
|
modem and use the appropriate configuration
|
|
methods.
|
|
|
|
For full API reference, see the GitHub Pages
