Can I read the content of RF register for LE1?

Alice

Hi

Can I read the content of RF register for LE1 by using the SPI of extern MCU?No matter the code of LE1 is  encrypted or not.

When set the LE1 to 0dBm,the TX power consumption is 11.1mA.When the radio is sending data and MCU is active,so the total power consumption is about 11.1mA+4.4mA = 15.5mA,right?

Thanks for everyone who answer me.

    Hi Alice,

    The RFSPI interface is not accessible on the pins, so that is not possible. You will then have to make a "wrapper" firmware on the LE1, or use a nRF24L01+ instead.

    The peak current consumption of the nRF24LE1 when transmitting (no ACKing) will be along the number that you posted, depending on the CPU speed you're running on. If you are using auto-ACK, the PTX will go into RX mode, which consumes more power than the transmission. Please see the Chapter 3 in the datasheet for more information about Enhanced Shockburst.

    Note: to reduce the peak current, you should set the MCU into PWRDWN=7 while waiting for the radio interrupt.

    Best regards Håkon
