HI! I'm in trouble with Spirit1 transceiver. Any help will be invaluable.

[GZeps.1]

Spirit1 normally makes reset, then, after any command of RX, TX or LOCKRX, LOCKTX it is always goes in error state Status registers are steady 0x02 and 0x27 and no further commands are executed, excluding reset and sleep. This is unknown error, I don't know what to do? Registers FA=0x02 and 0xFB=0x40. They also are not in table of possible values, so I'm completely lost. May be here are initialization problems, I have not any initialization sequence hints or examples. All other registers are as they should be after reset. What to do?

Hi GZeps.1

What controller are you using to put the low level on the SDN pin?

The problem may be in the voltage applied to the voltage applied to the SDN pin. Analyze the voltage that is coming to the SDN pin
