error (-11) while try to start advertising

[Mr.NCK]

Hi,

I have tried to follow the below tutorial (https://www.youtube.com/watch?v=hY_tDext6zA&t=933s). While I am trying to advertise the ble by following that webinar. I have got the below log error.

Kindly, help me to resolve that error.

Thanks & Regards,

Hi Navin,

Would you mind uploading your project here so I can have a look? The error code corresponds to -EAGAIN and might happen if you try to use the BLE stack before it has been initialized.

Best regards,

Hi Navin,

The semaphore was initialized with the initial value set to '1' instead of '0', which caused k_sem_take() to return immediately before the BT stack was ready. 

In remote.c, try:

static K_SEM_DEFINE(bt_init_ok, 0, 1);

Instead of:

static K_SEM_DEFINE(bt_init_ok, 1, 1);

Best regards,
