Hi,
I'm trying to setup a simple BLE Advertising beacon the broadcasts once per 3 seconds, th problem Im having is it will do this for about 10 broadcasts then stop and rest for 7ish seconds before starting again?
any suggestion for what I'm doing wrong?
I am prototyping using bluefruit library that uses softdevice S140 7.3.0
below is my code.
void startAdv(void)
{
// Advertising packet
Bluefruit.setName("DROID");
Bluefruit.Advertising.addFlags(BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE);
Bluefruit.Advertising.addTxPower();
Bluefruit.Advertising.addName();
Bluefruit.Advertising.setType(BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED); // for XIAO BLE
Bluefruit.Advertising.restartOnDisconnect(true);
Bluefruit.autoConnLed(false);
Bluefruit.Advertising.setInterval(500, 3000); // in unit of 0.625 ms
Bluefruit.Advertising.setFastTimeout(1); // number of seconds in fast mode
Bluefruit.Advertising.start(0); // 0 = Don't stop advertising after n seconds
}
void disconnectPin(uint32_t ulPin)
{
if (ulPin >= PINS_COUNT)
{
return;
}
ulPin = g_ADigitalPinMap[ulPin];
NRF_GPIO_Type *port = nrf_gpio_pin_port_decode(&ulPin);
port->PIN_CNF[ulPin] =
((uint32_t)GPIO_PIN_CNF_DIR_Input << GPIO_PIN_CNF_DIR_Pos) | ((uint32_t)GPIO_PIN_CNF_INPUT_Disconnect << GPIO_PIN_CNF_INPUT_Pos) | ((uint32_t)GPIO_PIN_CNF_PULL_Disabled << GPIO_PIN_CNF_PULL_Pos) | ((uint32_t)GPIO_PIN_CNF_DRIVE_S0S1 << GPIO_PIN_CNF_DRIVE_Pos) | ((uint32_t)GPIO_PIN_CNF_SENSE_Disabled << GPIO_PIN_CNF_SENSE_Pos);
}
void setup()
{
flash.begin();
Bluefruit.begin();
Bluefruit.setTxPower(+8); // Check bluefruit.h for supported values
flashTransport.begin();
if (flashTransport.runCommand(0xB9)== false)
{
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, LOW);
while (1)
{
yield();
}
}
flashTransport.end();
flash.end();
for (int i = 0; i < 25; i++)
{
disconnectPin(i);
}
sd_power_mode_set(NRF_POWER_MODE_LOWPWR);
sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);
startAdv();
suspendLoop();
__WFE();
__WFI();
sd_app_evt_wait();
}
