Note 1: 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:
A logic signal is needed to enable/disable PA/LNA part, P0.20 is used to achieve this purpose.
Set P0.20 to high will enable PA/LNA. Set P0.20 to low will disable PA/LNA to deep sleep mode.
As the most basic use case, simply set the P0.20 to high will enable PA/LNA part always.
If you need to get lower power consumption, you need to accurately control the timing of the
PA/LNA when it need to work, in accordance with the provisions of the timing will be closed.
In order to achieve this goal, need to know exactly time to control the PA/LNA. By calling the
Notify Radio() function, you can know when the RF activation, resulting in the appropriate timing to
control P0.20.
#define PIN_5518CTR 20

if(m_radio_active_flag)//enable PA
m_radio_active_flag=0;
nrf_gpio_pin_set(PIN_5518CTR);//pin 20
err_code = app_timer_start(m_apps_timer_id, APP_TIMER_TICKS(10,
APP_TIMER_PRESCALER) , NULL);//app_timer 10ms
APP_ERROR_CHECK(err_code);

We have modified the source code ble_radio_notification.c that provided by nRF51 SDK, to
achieve this purpose.
The
modified
ble_radio_notification.c
is
located
in
the
directly
\nRF51_SDK_9.0.0_2e23562_5518PA_DEMO\components\ble\ble_radio_notification of source code
package we provided.
By add the ble_radio_notification.c file to the project, the Radio Notify() function can be used to
detect if RF is active, below is the key code for the usage of Radio Notify() function:
bool m_radio_active_flag=0;
void ble_radio_active_evt(bool radio_active)
m_radio_active_flag=1;
static void radio_notification_open_init(void)
uint32_t err_code;
err_code = ble_radio_notification_init(NRF_APP_PRIORITY_LOW,
NRF_RADIO_NOTIFICATION_DISTANCE_800US,

ble_radio_active_evt,1);
APP_ERROR_CHECK(err_code);
The following main function is an example that to show you how to enable PA/LNA part in your
project:
int main(void)
uint32_t err_code;
app_timers_init();
nrf_gpio_cfg_output(PIN_5518CTR);
nrf_gpio_pin_set(PIN_5518CTR);
nrf_delay_ms(2000);
ble_stack_init();
gap_params_init();
services_init();
advertising_init();
conn_params_init();
err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
APP_ERROR_CHECK(err_code);
radio_notification_open_init();
// Enter main loop.

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.
