The Fast mode VS normal mode at the NRF52832

Question

Dear Karl, 
 We want to optimize the distance at the nRF52832's audio product. 
 The nRF52832 was working the fast mode ; Will the distance be better when the nRF52832 is setting the normal mode? 
 Best regards.

Hello Yin, 
 We want to optimize the distance at the nRF52832's audio product. 
 Could you clarify which type of audio product you are referring to here? Please note that we only support LE Audio development on the nRF5340 SoC, since this SoC is made with LE Audio specifically in mind.

 Could you clarify which modes you are referring to here as well? Usually, 'the fast and slow modes' refer to advertising modes, but I am not certain how this would relate to your audio product and expected range. Best regards, Karl

Hello Karl, 
 Could you clarify which type of audio product you are referring to here? 
 Yin: This audio product isn't the LE Audio, This is achieved by the 2.4G private protocol from me. 
 Could you clarify which modes you are referring to here as well? 
 Yin: Is the RF's reception sensitivity of normal mode better than that of fast mode when the RF is working in the 2M data rate? 
 Best regards.

Hello again, Yin Oh, I see - thank you for clarifying. I was not sure what you were asking about, since you previously have been asking about LE Audio and the nRF5340 as well, but now it is more clear.

 In general you are less susceptible to noise and on-air data corruption the shorter you are transmitting. Switching til 2M PHY will require half the time to transfer the same payload as if you were using the 1M PHY, and so you will actually have less data corruption on the link when you use the 2M PHY. If you want to maximize range of your transfer you will need to use the CODED PHY, but this comes at a considerable cost to the throughput of your link. Best regards, Karl
