Good Day.
I get an MPU FAULT when creating a new thread where I want to display the RSSI value.
Looking at similar requests in the community, there were recommendations to increase CONFIG_MAIN_STACK_SIZE, I increased this parameter to 2048, but it didn't help.
I have one thread (Priority = 7) in my program now (taken from the BLE example), it sends data over bluetooth.
void send_data_thread(void)
{
while (1) {
/* Simulate data */
simulate_data();
/* Send notification, the function sends notifications only if a client is subscribed */
my_lbs_send_sensor_notify(app_sensor_value);
k_sleep(K_MSEC(NOTIFY_INTERVAL));
}
}
K_THREAD_DEFINE(send_data_thread_id, 2048, send_data_thread, NULL, NULL, NULL, 7, 0, 0);
When adding a second thread (Priority = 8) that should read RSSI, an error occurs.
void rssi_thread(void)
{
int8_t rssi = 0xFF;
while(1){
read_conn_rssi(default_conn_handle, &rssi);
LOG_INF("RSSI level = %d\n", rssi);
k_msleep(1000);
}
}
K_THREAD_DEFINE(rssi_thread_id, 2048, rssi_thread, NULL, NULL, NULL, 8, 0, 0);
If I move all the code from rssi_thread() to main(), everything works without errors.
Can you please tell me what could be the reason?
Thanks.
