Hi,
In my project, I need turn on/off the hfxo, I found when i configure the hfxo, the nfc is not working. Here is my code:
void gps_server_function(void *p1, void *p2, void *p3)
{
msg_gps_type_t item;
int ret;
static bool gps_power_lock = false;
while (true)
{
k_msgq_get(&gps_task_msgq, &item, K_FOREVER); // 等待消息
switch (item)
{
case GPS_OPEN_LOCK:
LOG_INF("open gps module");
sim66md_power(1);
gps_power_lock = true;
nfc_t4t_emulation_stop();
ret = clock_control_on(clock_dev, CLOCK_CONTROL_NRF_SUBSYS_HF);
if (ret != 0)
{
LOG_INF("Failed to start HFCLK: %d", ret);
}
else
{
LOG_INF("HFCLK started successfully.");
nfc_t4t_emulation_start();
}
break;
case GPS_FETCH:
sim66md_power(1);
int ret = sim66md_get_rmc(&rmc_frame, 90);
if (ret < 0)
{
rmc_frame.valid = false;
LOG_ERR("can not get valid rmc message");
}
else
{
LOG_INF("coordinates: (%f,%f); speed: (%f);",
minmea_tocoord(&rmc_frame.latitude),
minmea_tocoord(&rmc_frame.longitude),
minmea_tofloat(&rmc_frame.speed));
}
if (gps_power_lock == false)
{
sim66md_power(0);
}
break;
case GPS_CLOSE:
LOG_INF("close gps module");
sim66md_power(0);
gps_power_lock = false;
clock_control_off(clock_dev, CLOCK_CONTROL_NRF_SUBSYS_HF);
LOG_INF("HFCLK stopped.");
break;
default:
break;
}
}
}
