nrf24l01+ IRQ current in between retries

[debraj]

Could you please let me know the current rating in between retries while transmitting.From the oscilloscope reading, that is not obvious. The documentation shows three idle modes.

1. power down mode: 900 nA
2. standby I mode : 26 uA
3. standby II mode : 320 uA

This are required for my research to accurately calculate the current consumptions.

So between the TX event and listening for incoming package will be the same as "average current during RX settling" = 8.9 mA. After the RX event if there's been no ACK and after the ARD, it will be the "average current during TX settling" = 8.0 mA. Please see chapter 5.1 of the nRF24L01+ product specification.

In the time after the end of the RX window and before the next TX settling it will be in standby-II mode. Please see Figure 10 on page 35 of the nRF24L01+ product specification.

Thanks for the insight.... I also observed that when the ARD value ( time between retries) is kept low, the packet success rate drops in indoor environment, probably because of slow fading nature of the channel. when the ARD value is increased, the PSR value improved. But the cost paid is the time duration when the transmitter is in standby I mode
