Detailed Description

Controls external PA/LNA support for the mesh radio operation.

The mesh PA/LNA module enables external power amplifiers and low noise amplifiers by setting user configured GPIO-pins during radio operation.

The PA/LNA is triggered some time before the radio operation starts, to allow the amplifiers to stabilize. The timing can be configured at compile time by changing MESH_PA_SETUP_TIME_US and MESH_LNA_SETUP_TIME_US. Note that the setup time cannot be longer than the radio rampup time (by default 40us on nRF52 and 140us on nRF51).

Typedef Documentation

◆ mesh_pa_lna_gpiote_params_t

typedef ble_common_opt_pa_lna_t mesh_pa_lna_gpiote_params_t

Configuration parameters for gpiote-based setup of PA/LNA.

Identical to the Softdevice parameters.

Definition at line 62 of file mesh_pa_lna.h.

Function Documentation

◆ mesh_pa_lna_gpiote_enable()

uint32_t mesh_pa_lna_gpiote_enable ( const mesh_pa_lna_gpiote_params_t * p_params )

Enables GPIOTE controlled PA/LNA triggering.

Parameter requirements:

The PPI channels must not collide with the mesh timer channel range (8-11).
The PPI channels cannot be the same for set and clear.
The PPI channels must be valid for the given chip configuration.
The GPIOTE channel ID must be valid for the given chip configuration.
The GPIO pins must be valid for the given chip configuration.

Parameters

[in] p_params Configuration parameters.

Return values

NRF_SUCCESS	The GPIOTE controlled PA/LNA triggering was successfully enabled.
NRF_ERROR_NULL	The parameter pointer was NULL.
NRF_ERROR_INVALID_PARAMS	One or more of the parameters broke the parameter requirements.

◆ mesh_pa_lna_gpiote_disable()

void mesh_pa_lna_gpiote_disable ( void )

Disables PA/LNA triggering.

Immediately stops any running GPIO signal.

◆ mesh_pa_lna_gpiote_params_get()

const mesh_pa_lna_gpiote_params_t* mesh_pa_lna_gpiote_params_get ( void )

Retrieves the current PA/LNA parameters.

Returns: The current PA/LNA parameters or NULL if disabled.
