Receive data from propel tx use XN297lbw chip was created by Bangdc

Dear All,

I have TX with XN297lb RF chip inside.
I want to use this TX to send data to arduino + NRF24L01+
In order to do that, I collected sequence from TX via PulseView tool and found:
- TX address: 0x12, 0xd6, 0x74, 0xbd, 0x71
- RX address: 0x15, 0x59, 0x23, 0xc6, 0x29
- Bind Channel: 0x0B
- Payload: 16
Then I used these value to config for my NRF24L01+ chip

#define BAYANG_RX_PACKET_SIZE 12 //Even though payload is 16, but I found with Configure XN297_CRCEN, payload will be add more 4 and set 16 via XN297_SetRXAddr()

	XN297_Configure(XN297_CRCEN, XN297_SCRAMBLED, XN297_1M);
	const uint8_t tx_address[BAYANG_RX_ADDRESS_LENGTH] = { 0x15, 0x59, 0x23, 0xc6, 0x29 };
	const uint8_t bind_address[BAYANG_RX_ADDRESS_LENGTH] = { 0x12, 0xd6, 0x74, 0xbd, 0x71 };
	XN297_SetTXAddr(tx_address, BAYANG_RX_ADDRESS_LENGTH);
	XN297_SetRXAddr(bind_address, BAYANG_RX_PACKET_SIZE);	
	XN297_RFChannel(0x0B);
	XN297_SetTxRxMode(TXRX_OFF);
	XN297_SetTxRxMode(RX_EN);

But with this RF setup, I can not get any payload from TX, ( NRF24L01_ReadReg(NRF24L01_07_STATUS) & _BV(NRF24L01_07_RX_DR) ) is alway False
Will be very appriciate if anyone help me check why this problem happened.
I also attached PulseView data that I collected via Saleae Logic tool.

Hi, maybe you lack some nrf24 init code, can you post your whole code?
( setup(), loop() ) or share it on github ?

Dear Goebish,
Thank you very much for your attention to my problem.
I will upload the whole source code based on this github: github.com/bikemike/nrf24_multipro/tree/rx_mode soon (about 5 hours latter when I come back home)
I'm using esp32 and nrf24L01+ so I modified that github for esp32.

Dear Goebish,
I attached source code (I converted your code to build on platform IO IDE)

File Name: rx_nrf24_esp32.zip

Detail:
1. I am using file Bayang.cpp to modify NRF config fit with tx address, bind channel, payload length

const uint8_t bind_address[] = {0x12, 0xd6, 0x74, 0xbd, 0x71};

NRF24L01_WriteReg(NRF24L01_11_RX_PW_P0, BAYANG_PACKET_SIZE); // length is 18

NRF24L01_WriteReg(NRF24L01_05_RF_CH, BAYANG_RF_BIND_CHANNEL); // Bind channel is 0x0B

if possible could you please help me confirm these values via Pulseview data that i attached?
One more thing: I uploaded an esp32 board as TX mode and the rest as RX mode(uncomment #define RX_MODE in file board.h), I received bind packet, but with PROPEL Remote control I was still not sucessful, there is no data come esp32+nrf24 module.
