JN5168 - Can't enter programming mode

Hi everyone! I've bought a JN5168 module (JN5168-001-M00), with a USB to TTL adapter (3,3V). I have some trouble entering the programming mode. The BeyondStudio flash programmer doesn't recognized the chip, appearing the error "Failed to read chip details on COM3".

I've check the connections from the module to the adapter and they are correct (RX to TX and viceversa, SPIMISO to ground through a switch, the same with RESETN but including a pull up resistor and a capacitor)

Do you know where the problem can be? There is few information about the JN5168, and it seems that many people have problems with it.


Thanks for the help!!
