How to reduce nrf24le1 power consumption?

[Cao Jean]

What is this mean? 0.12mA is very small. Why smaller than other very much?

Thanks~

Hi,

As mentioned in the product specification, this is the average current consumption with an average data rate 10 kbps and full packets.

The nRF240LE1 will stay in sleep mode when the packet is clocked into its Data Out Register, thus it will only use the high current when transmitting the packet. The average current consumption will therefore be the sleep current pluss the currect cunsumed while transmitting.

Best regards,

Jørgen

I have made a mouse, requir 125hz/s report rate, transmit 13bytes every time. So it means 1625bps? I also can make its current 0.12mA at -6dBm?

But i test my mouse, its current is about 8mA at -12dBm(dont contain mouse sensor and other compoment). I use nRFgo SDK, device mode 0.

mode 0:asynchronous mode,frequency agility

mode 1:asynchronous mode,frequency hopping spread spectrum

mode 2:semi-synchronous mode,frequency agility

mode 3:semi-synchronous mode,frequency hopping spread spectrum

mode 4:semi-synchronous mode,low latency frequency hopping spread spectrum

Thanks~
