I know it's too old but the nrf can be reset using code and I did it. Check this out How to automatically reset the nrf24l01+ with code? - Arduino Stack Exchange

Hola, veo que esto lo haces para un pic con ccs c compiler, ¿este es utilizando la librería nrf que rueda por la web?, como mejoras la estabilidad de la conexión? , muchas gracias por tu ayuda

Hi, Emon, Regarding your 4th step: 4)write status register as 0x0e;

Why writing status reg ( I think you mean reg 0x07) as 0x0E? The low 4 bits of this register is read-only, according to "nRF24L01+ Product Specification v1.0", so I think writting 0x0E is meaningless. Please help confirm this.

YA LO SOLUCIONE : AGREGE ESTO A LA CONFIGURACION INICIAL

output_low(RF_CS); spi_write(0xE1); //FLUSH_TX output_high(RF_CS);

output_low(RF_CS); spi_write(0xE2); //FLUSH_RX output_high(RF_CS);

SUERTE

the problem as far as i understand is that, when the MCU resets, the NRF24L01+ is not under reset values. So at every reset, do the following steps:

1)use power down mode (PWR_UP = 0) 2)clear data ready flag and data sent flag in status register 3)flush tx/rx buffer 4)write status register as 0x0e;

works perfectly . Data is received even after i reset the MCU

I can't really think of anything. You should make sure to clear the status register and the FIFOs and reconfigure all configuration, but if that still doesn't help, I'm afraid I don't really have any other suggestion than to add a transistor to your design to be able to toggle power.

Thank you for the answer, Ole.

As we won't be able to reset the radio, could you, please, explain us what is the behavior of the chip when a communication is stopped when still in course, in other words: how does the chip functions when it receives only some bits of a complete byte?

Unfortunately, there is no way to reset the nRF24L01+ without powering it off and on again, and I can't really think of any other workaround for this problem.
