CC1101 hibernation mode

[weekroom]

When I was using CC1101, I found that the library only provided the standby API function of CC1101, but no API function of sleep mode. Will updates be added in the future?
I found that the CC1101 can be put into sleep mode by adding an SPI instruction to the standby() function, such as this one:
#define RADIOLIB_CC1101_CMD_POWER_DOWN 0x39 //This one is in the CC1101.h file
SPIsendCommand(RADIOLIB_CC1101_CMD_POWER_DOWN);
Before use:

After use:

I see the specification is 0.6uA, I do not know whether other register configurations are needed to continue to reduce power consumption

I have confirmed with the hardware engineer that the reason for such a large power consumption is the 5v to 3.3v circuit. If the power supply is 3.3v, it is estimated that it can reach 0.6uA as stated in the specification

Several other radios (SX127x, SX126x etc.) have a sleep method, the only reason it was not implemented for CC1101 is that it wasn't requested yet. Feel free to submit a PR for it ;)
