Note 1: P0.20 and P0.24 are reserved for PA control internal.

Note 2: An internal 4.7μF bulk capacitor has been included on the module. it is good design

practice to add additional bulk capacitance(e.g 10uF) as required for your application.

General Purpose I/O:

The general purpose I/O is organized as one port enabling access and control of the 32 available

GPIO pins through one port. Each GPIO can be accessed individually with the following user

configurable features:

 Input/output direction

 Output drive strength

 Internal pull-up and pull-down resistors

 Wake-up from high or low level triggers on all pins

 Trigger interrupt on all pins

 All pins can be used by the PPI task/event system; the maximum number of pins that can be

interfaced through the PPI at the same time is limited by the number of GPIOTE channels

 All pins can be individually configured to carry serial interface or quadrature demodulator

signals

PA control:

Additional logic signals are needed to control TX PA and RX LNA. On the nRF51 there was an

option to use the VDD_PA pin to detect when the radio was in TX mode, but this is not an option on

the nRF52, making the SoftDevice solution necessary. The S132 SoftDevice for the nRF52 has

support for enable/disable switching of external Power Amplifiers (PA) and LNA using GPIO pins.

On the module, P0.20 and P0.24 are reserved to control PA and LNA, so these two pins can Not

be allocated to other usage.

The truth table of PA/LNA control signals as bellow:

PIN24 PIN20 PA status

1 0 TXEN

0 1 RXEN

0 0 IDLE

1 1 INVALID

The following function can be used to enable PA/LNA signal with P0.20 and P0.24. Add this

function to your project and call it after ble_stack_init():

static void pa_assist(uint32_t gpio_pa_pin,uint32_t gpio_lna_pin)

{

ret_code_t err_code;

4

static const uint32_t gpio_toggle_ch = 0;

static const uint32_t ppi_set_ch = 0;

static const uint32_t ppi_clr_ch = 1;

// Configure SoftDevice PA assist

ble_opt_t opt;

memset(&opt, 0, sizeof(ble_opt_t));

// Common PA config

opt.common_opt.pa_lna.gpiote_ch_id = gpio_toggle_ch; // GPIOTE channel

opt.common_opt.pa_lna.ppi_ch_id_clr = ppi_set_ch; // PPI channel for pin clearing

opt.common_opt.pa_lna.ppi_ch_id_set = ppi_clr_ch; // PPI channel for pin setting

// PA config

opt.common_opt.pa_lna.pa_cfg.active_high = 1; // Set the pin to be active high

opt.common_opt.pa_lna.pa_cfg.enable = 1; // Enable toggling

opt.common_opt.pa_lna.pa_cfg.gpio_pin = gpio_pa_pin; // The GPIO pin to toggle

opt.common_opt.pa_lna.lna_cfg.active_high = 1;

opt.common_opt.pa_lna.lna_cfg.enable = 1;

opt.common_opt.pa_lna.lna_cfg.gpio_pin = gpio_lna_pin;

err_code = sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &opt);

APP_ERROR_CHECK(err_code);

}

5

The following main function is an example that to show you how to enable PA/LNA signal in your

project:

int main(void)

{

uint32_t err_code;

// Initialize.

APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);

ble_stack_init();

pa_assist(24,20);

gap_params_init();

services_init();

advertising_init();

conn_params_init();

err_code = ble_advertising_start(BLE_ADV_MODE_FAST);

APP_ERROR_CHECK(err_code);

// Enter main loop.

for (;;)

{

power_manage();

}

Hardware RESET:

There is on-chip power-on reset circuitry, But can still be used in external reset mode, in this case,

GPIO pin P0.21 as an external hardware reset pin(Active Low). In order to utilize P0.21 as a hardware

reset, the UICR registers PSELRESET[0] and PSELRESET[1] must be set alike, to the value of

0x7FFFFF15. When P0.21 is programmed as RESET, the internal pull-up is automatically enabled.

HW debug and flash programming of Module:

The Module support the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful

mechanism for non-intrusive debugging of program code. Breakpoints, single stepping, and

instruction trace capture of code execution flow are part of this support.

Pin Flash Program interface

SWDIO Debug and flash programming I/O

SWCLK Debug and flash programming I/O
