# Overview
|
||
|
|
|
||
|
|
This package provides necessary Makefiles and glue code to use the Nordic S132
|
||
|
|
SoftDevice as Bluetooth BLE transport for RIOT's 6lowpan stack.
|
||
|
|
|
||
|
|
# Usage
|
||
|
|
|
||
|
|
"gnrc_netdev_default" has a dependency to "nordic_softdevice_ble", so all
|
||
|
|
examples automatically download the SDK and compile / link / flash all needed
|
||
|
|
code.
|
||
|
|
|
||
|
|
If you want to manually set up included modules, add "USEPKG +=
|
||
|
|
nordic_softdevice_ble" to your application's Makefile.
|
||
|
|
|
||
|
|
See README-BLE-6LoWPAN.md for instructions on how to set up 6lowpan over BLE on
|
||
|
|
Linux.

# Known issues
|
||
|
|
|
||
|
|
- floating point ABI mismatch
|
||
|
|
|
||
|
|
The Nordic binaries are compiled using hard float ABI, which RIOT currently
|
||
|
|
doesn't support (RIOT's context switching code doesn't preserve the floating
|
||
|
|
point registers). If the softdevice is compiled in, RIOT will be compiled with
|
||
|
|
hard float ABI in order for the linking to succeed. This works for some
|
||
|
|
application, but will lead to serious and hard-to-find bugs for code using
|
||
|
|
floating point instructions.
|
||
|
|
|
||
|
|
Hopefully, either the RIOT community adds hard-float support, or Nordic
|
||
|
|
releases a soft-float version of the used binaries.
