nRF24L01+ Pipe2 to Pipe5 not working.

Question

In an RFID application, we have nrf24l01+ and SMT32F4xx on the Reader and nrf24lu1+ on the tag. 
 The Reader is acting as multiceiver currently. 
 Pipe 0 and Pipe 1 are working fine. We have problem with Pipe 2 to Pipe 5. 
 RF channel is 2 , payload is 10, 250Kbps data rate. 
 Following is the register dump on the Reader:
RX_ADDR_P0 = e7 e7 e7 e7 e7,
RX_ADDR_P1 = e1 e1 e1 e1 e0,
RX_ADDR_P2 = d2,
RX_ADDR_P3 = c3,
RX_ADDR_P4 = b4,
RX_ADDR_P5 = a5,
CONFIG = b,
EN_AA = 3f,
EN_RXADDR = 3f,
SETUP_AW = 3,
SETUP_RETR = 4f,
RF_CH = 2,
RF_SETUP = 26,
RX_PW_P0 = a,
RX_PW_P1 = a,
RX_PW_P2 = a,
RX_PW_P3 = a,
RX_PW_P4 = a,
RX_PW_P5 = a.

I haven't seen you configure the RX_ADDR_P0 in the code. It should be configured.
I suspect there could be a mismatch on the order of byte (byte endianness). 
 You can try to test by using RX_ADDR_P1 = {0xE1, 0xE1, 0xE1, 0xE1, 0xE1}; RX_ADDR_P2 = 0xD2 
 and then try both:
 TX_addr[5] = {0xE1,0xE1,0xE1,0xE1,0xD2};
and
TX_addr[5] = {0xD2,0xE1,0xE1,0xE1,0xE1}; 
 respectively, to see if it's the case. 
 I don't know how you write the register with nrf24_writeRegister() but I would suggest to use hal_nrf_write_multibyte_reg() function in hal_nrf.c .
Or better could you use hal_nrf_set_address() as in the example ? I suggest to test first with both side from the code from the example to make sure it works before moving to your code.
