rf_host_device

About

rf_host_device is a precompiled and linked binary software by JayLabs s.r.o. which implements and handles control of the data streams on top of a wireless protocol using the Nordic Semiconductor SDK.

Supported systems

rf_host_device is prepared for nRF52 family chips from Nordic Semiconductors loaded with s140 softdevice. The device was namely tested with the nRF52833 chip.

Peripheral Usage

rf_host_device has been developed following the same philosophy as the Nordic's softdevice, the package is bundled and then distributed as a binary, routing the peripheral access to the target application after reserving the required peripherals.

In addition to the nRF52 peripherals already reserved by softdevice (s140 manual), rf_host_device reserves the following peripherals:

• RADIO
• TIMER3
• SWI5

Getting started

• Run the rfhdev_init(const rfhdev_config_t * p_config) for registering general API callback functions
• Run the rfgw_host_init() for for initializing the RF Host device

Restrictions

• rfgw_host must not be initialized (rfgw_host_init()) if the softdevice has been enabled first
• softdevice must not be enabled if the rfgw_host has been previously initialized
• once the rfgw_host has been initialized, it cannot be uninitialized. For switching to the softdevice, the chip must be restarted.
