Getting Started with Bluetooth LE Audio Using the Nordic NRF5340 -- DC to Daylight 19

Hi Sanmeet. I started to look into this when I was putting the video together, but it was a little too deep to get into at the time... it looks like there is a walkie-talkie demo. See in the nordic forum: https://devzone.nordicsemi.com/f/nordic-q-a/96907/nrf5340-audio-dk-walkie_talkie-no-bidirectional

I haven't tried, but I might later this week if I have time. Also, I think you may have to solder some jumpers to get the digital mic to work as an input - don't quote me, but I think I saw that in the datasheet.

HI Derek, what changes do I need to make if I want a bidirectional audio transmission like an intercom using two boards? TIA!

I do like thunderstorms.

I also take lightning photos.

You can also use some filters to keep a lot of the man made noises out.

You certainly could, though I wonder about the external noise you would also pick up from unwanted sources... like automobiles, or other man-made things. It may be more enjoyable to use it as a traditional bluetooth speaker and connect the source to a computer or phone.  Personally I use one of those "voice recognition devices" and request it to play thunderstorm sounds.

It would have the advantage that you could control it however you want though, which makes the application appealing.

Interesting board.

I was wondering if you could use the pair to relay bird songs from outside the house to inside.

When we close up the house for using the air conditioner, we also lock out the songs of the many birds around the house.

It would be interesting to see an end-to-end latency test from the line input of one dev kit to the headphones output of another dev kit in broadcast mode.

Does the demo application allow for a single dev kit to receive both left and right channels from a gateway or would this require three dev kits configured as gateway, left & right?

Hi Finn.

Thank you for the input regarding the recover flag. Afterwards, I dug into the forums a bit more and the nRF5340 documentation as well, and it became more clear to me. Initially I didn't realize that *recover* equated to reset registers including app protect. Thank you for further explaining!

somewhere around 11:40 or so Derek refers to using  -- recover and not exactly knowing what it is about. You use that basically completely reset the device including special registers used for APPROTECT.
