} nrf_app_irq_priority_t;...
Hi all,
I'm trying to use NRF24L01, using REUSE_TX_PL command,
the data sheet says as long as CE keep high, the chip will transmit the payload continuously, what i wondering...
Hi
Did you have tested the power current of nRF24LU1 when RF was off and USB worked normally?
We want it less than 4mA. Could you have any idea to make it? Thanks.
