Semtech SX1276 Driver Bug

Dear Semtech team,

I have been struggling to make your SX1276 driver (as is shown in the tools section of the official web page outlining the features of the SX1276 on semtech.com) work as intended in FSK mode.

After setting the chip to Rx mode using Radio.Rx(0) (meaning that it should be in continuous RX mode) I am getting DIO0 interrupts with RegOpMode 13 (indicating that it is currently in TX mode) and IrqReg2 indicating that Fifo is empty. Note that this seems to happen at random times. But after appearance of this behavior, resetting the radio won't put the radio into defined state (register still reads the same). Note that reset signal is known to be present and is known to be implemented correctly.

Are recommended practices (like checking PLL or other internal blocks for having configured themselves after setting rx mode) followed in the official driver implementation, or does the user need to take care of it him/herself?

I am experiencing extensive problems considering the usage of the driver at packet rates above 210/second (of which 2/3 are tx and 1/3 is rx).

Radio settings are as follows:

Following functions are called to set receiver and transmitter parameters:

The CustomInit function referenced in the code is as follows:

Please note that the init function has been adjusted to account for first time settings (setting event callback functions):

Thank you for your answer in advance.

With kind regards from Germany

Edit:

I need to correct that the radio is NOT in TX mode upon interrupt, but in RX mode. Still, DIO0mapping is set to PayloadReady and an interrupt gets generated with bits CRCok and PayloadReady (fifo state) bits in IrqReg2 are not set.
