The range on the nRF24L01+ is not great, it shares the 2.4GHz band with WiFi and microwave ovens andoften these will interfere noticably and reduce the range, especially on the higher baudrates. I've donesomething similar using the 2M baudrate and needed to use the modules with built-in PA to get usablerange. 30m is pushing it, really pushing it.
What quality audio do you want?
How much latency can you tolerate?
What about clock-recovery after packetization/reconstruction - have you thought about that?
For sending audio from a microphone, a wireless microphone is the obvious solution...
Hi Mark.I've read that NRF24L01 has a range of 1000 meters.
In my case, it's probably around 20 meters and the wall is not reinforced.Just enough to make out what's being said.
2-3 seconds tops.
I don't know what you mean by this.
Do you have a specific model in mind?
Eventually I will be needing an MCU on the side which has the microphone. Because, as I've said, I will send some data back from the other side that will activate a sensor.
