What is the power consumption of ESB vs BT/ BLE ?

Hi all.

By reading this post i've tried to check for real KBPS performence in a typical application.

I've set up 2 NRF24L01+ arduino modules and I've used 2 Arduino nano, one as Transmitter and the other as receiver. Both using IRQ to sync. Packet length and Ack size are both 32bytes.

Data Rate is 2MBPS and power is set to LOW (transcrivers are very close one to another).Transmitter send a packet every 200ms. Round Trip Time is taken for eack packet. Stats are printed every 100 packets. Here the math:

RTTime = TransmissionTime(PKT)+130uS+TransmissionTime(ACK)+130uS (not sure about last 130uS)

Total bits sent: (41*8+1)*2=658bit (1 byte Preamble, 5 bytes Address, 1Byte CFC plus 1bit, 32 bytes payload/ack, 2 bytes CRC)

Kbps would then be: 658000/(RTTIme-260us) and with a RTTime of 589uS we should get 2000KBPS.

Is math correct? :-)

what is maximum throughput possible with NRF52x?

Andrew -- Good question! The nrf_esb module expands PAYLOAD_LEN to 8 bits if payloads larger than 32 bytes are enabled.

How is the maximum payload more than 64 bytes? PAYLOAD_LEN is 6 bits wide.

Great info, thanks. Wish I would have seen this earlier.

Very nice Daniel.
