NUCLEO-WL55JC1 for instant digital audio transmission

Kenney

Hello

I want to build an In-Ear Monitor system for performing music live. This system gets an audio signal from a sound card. Transmits it wirelessly (around 865MHz) to a bodypack receiver and plays the audio with virtually no delay.

I stumbled upon the NUCLEO-WL55JC1 Development board, which I thought may can do what I need on the RF and DSP part.

I was however curious if anyone can tell me if I can connect two units, make a digital modulation, transmit from one unit to the other, demodulate the signal and play it from an audio unit with virtually no delay. 

I'm hesitant about ordering a couple of units as I think their intended purpose is less critical about small delays. 🙂

Thanks in advance!

Strikes me as being ill-suited. You can broadcast small packets, say 64-bytes, so latency in the capture, transmission, replay. Would want the radio faster than the data capture.

The packets have preamble and then checksums

Tips, buy me a coffee, or three.. PayPal Venmo Up vote any posts that you find helpful, it shows what's working..

Thank you for clearing that up! 

Do you know of any MCU that might be well suited for the purpose?
