Is there any set of register values for the CC1125 that will make it transmit with a preamble longer than 30 Bytes?
Setting a very long EVENT0 time is easy, but PREAMBLE_CFG1.NUM_PREAMBLE only goes up to 30 Bytes. It seems that longer preambles can be transmitted by strobing TX when the TX FIFO is empty, but that adds overhead to the MCU controlling the radio.
