DA14585 range extender

Hi Dialog expert

I would like to implement range extender on DA14585 using SDK 604
I look at reference design Range Ext example and try to move the code to SDK604 but fail

I wounder that DIAGPORT_SEL and DIAGPORT_REVERSE seems to be removed at datasheet.h on SDK604.

I modify the app_range_extender_enable on app_range_ext.c as following

void app_range_extender_enable(void)
{

//SetBits32(BLE_CNTL2_REG, DIAGPORT_SEL, 0); // BLE diag port
//SetBits32(BLE_CNTL2_REG, DIAGPORT_REVERSE, 0); // diag port not reversed

SetBits32(BLE_CNTL2_REG, 0x18, 0); // BLE diag port
SetBits32(BLE_CNTL2_REG, 0x20, 1); // diag port not reversed

// Select signals
SetBits32(BLE_DIAGCNTL_REG, DIAG1, 0x28);
SetBits32(BLE_DIAGCNTL_REG, DIAG2, 0x08);

// Enable Diagnostic at BLE core
//SetBits32(BLE_DIAGCNTL_REG, DIAG0_EN, 1); // enable Diag ports.
SetBits32(BLE_DIAGCNTL_REG, DIAG1_EN, 1);
SetBits32(BLE_DIAGCNTL_REG, DIAG2_EN, 1);

// Enable Diagnostic at GPIO multiplexing

SetBits16(P04_MODE_REG, PID , 18);
SetBits16(P04_MODE_REG, PUPD, 3); //TXEN = P0_4

SetBits16 (P02_MODE_REG、PID、18);
SetBits16(P02_MODE_REG, PUPD, 3); //RXEN = P0_2

// SetBits16(P07_MODE_REG, PID , 18);
// SetBits16(P07_MODE_REG, PUPD, 3); //wlan coexistence = P0_7

}

I would like to use P0_4 as TX enable and P0_2 as RX enable.
Do anyone give me some tips to make it works?
