Hi,

Questions regarding our LE Audio solution should be directed to your Regional Sales Manager, as we are not able to discuss future releases or roadmaps here on DevZone. If you do not know who the sales manager for your region is, please send me a private message with your location so I may provide you with their contact information.

Hi, ovinid ,

has le audio been released?. As I already mentioned I want to record sound from I2S MIC and transfer the sound data over BLE. I thought the above applications are not helpful for my case. Kindly, guide me to achieve the requirement.

Thanks & Regards,

Navin

This builds at least, but there are still a lot of issues you need to fix, mostly due to it not being based on the 1.7.1 sample.

I would recommend looking at v1.7.1/nrf/samples/bluetooth/peripheral_uart, and adjust your project to me more like that.

Hi oivind,

I want to send an I2S raw data through ble for that. I write the below application. It basically shoots a configure error Kindly check and revert back

Ok, so looks like you are adding your I2C code to an older version of peripheral_uart, not the 1.7.1 version? That's why you are getting warnings due to deprecated function names.
I would strongly recommend using the 1.7.1 version of peripheral_uart if you are building on 1.7.1.

The build error is due to the arguments in the LOG_INF() calls in num_comp_reply(). Cast the auth_conn arguments as (void *) and it should build.

static void num_comp_reply(bool accept)
{
	if (accept) {
		bt_conn_auth_passkey_confirm(auth_conn);
		LOG_INF("Numeric Match, conn %p", (void *)auth_conn);
	} else {
		bt_conn_auth_cancel(auth_conn);
		LOG_INF("Numeric Reject, conn %p", (void *)auth_conn);
	}

	bt_conn_unref(auth_conn);
	auth_conn = NULL;
}

Hi,

Could I see your prj.conf? There seems to be some options there that are causing the issues.
