Configuration bits with SPI module for nRF2402 transmitter

[Ali Emre TUNCA]

Hi!

I am trying to make basic temperature nodes with nRF2402.

The receiver is nRF24L01 transceiver.

My question for nRF2402; is it possible to send config bits via SPI module of any MCU. For ShockBurst, i have to send 19bits. But, i can send 3bytes via spi.

Thanks for your helps!

Hi,

Since SPI modules are operating with whole bytes, it is not possible to use them with nRF2402. You'll have to use "bit banging" to configure the nRF2402. You could consider using packet lengths that adds up with a whole number of bytes in order to use a SPI module for the transmission part of your protocol.
