WE are trying to use the BX3105 SPI interface.
We have set in GPIO(17) high and the SPI does seem to work for the first frame.
We get a reply

However any commands sent are not implemented, also the BX3105 relies DUMMY_SLAVE but the command is not in the correct frame.
The second frame replied from the BX3105 is all zeros
The third frame starts with zeros and then after 15 BYTES sends the DUMMY_SLAVE message.
This is then not read correctly as it does not lie within the expected frame.
The fourth byte is again all zeros
The fifth byte is again the dummy message but again starting in the middle of the expected frame.
Can anyone help with this problem so we can use the BX3105 module
