No, for the nRF52832 the RADIO is able to send multiple packets one after the other without having to disable and re-enable the RADIO between packets.

Thanks a lot for explanation!

Does it mean that I have to restart radio every 16 or 4 ms on transmitter to be sure the perfomance will be stable?

Does the same rule work for nRF52832?

Hi,

The nRF51822 has a maximum consecutive transmission time.

If you stay in tx for longer than the PLL will drift in frequency (the PLL is in open loop in TX mode). So being able to receive packets for anything longer than that will depend on crystal drift and temperature, and a portion of luck...
