How to Use NRF52 as a Line-one-master-two-slave Microphone transmission

[spchen]

Hi ,

  I'm working on a 2.4GHz wireless microphone project now.

  I want to make a scheme of  two microphones transmitting to a single receiver(2T1R)。And ,i have tested this idea with nrf52832 using ESB，but i found the interference is ivery serious.I use two nr52-DK as microphones (esb_ptx examples) to transmit voice data (16KBps *2)to other one  nr52-DK (esb_prx), All nr52-DKs operate at the same channel (frequency) ; When I statistics packets in prx, I found that the packet loss was serious.

   So do you have any suggestions for me?Or is it feasible?

Hi

How do you synchronize the two PTX devices, to avoid them sending data at the same time?

You might want to have the two PTX device use different RF frequencies to avoid interference between them, and set up the PRX to switch between the two frequencies to receive data from one or the other.
