@exdj21 said in RaspBerry PI3 B + Dragino HAT ( RF95 / RFM95 ) = RF24_NOP error:

RF24_NOP

What is "RF24_NOP" and what is it used for?

I'm trying to use the mysensors library 2.1.1, but it is giving this error:

What I am using:

• Raspberry pi3 B
• Linux Raspbian
• Dragino HAT v1.3 ( RF98 - 433Mhz )
• MySensors library 2.1.1

What I have made so far:

The RFM95.cpp code part:

#if defined(LINUX_SPI_BCM)
	uint8_t * prx = spi_rxbuff;
	uint8_t * ptx = spi_txbuff;
	uint8_t size = len + 1; // Add register value to transmit buffer

	*ptx++ = cmd;
	while (len--) {
		if (aReadMode) {
			*ptx++ = RF24_NOP;
		} else {
			*ptx++ = *current++;
		}
	}
	_SPI.transfernb((char *)spi_txbuff, (char *)spi_rxbuff, size);
	if (aReadMode) {
		if (size == 2) {
			status = *++prx;   // result is 2nd byte of receive buffer
		} else {
			status = *prx++; // status is 1st byte of receive buffer
			// decrement before to skip status byte
			while (--size) {
				*buf++ = *prx++;
			}
		}
	} else {
		status = *prx; // status is 1st byte of receive buffer
	}
#else
	status = _SPI.transfer(cmd);
	while (len--) {
		if (aReadMode) {
			status = _SPI.transfer((uint8_t)0x00);
			if (buf != NULL) {
				*current++ = status;
			}
		} else {
			status = _SPI.transfer(*current++);
		}
	}
#endif

any idea?
