how to Change TX_ADDR? #523

Closed imohammad74 closed 4 years ago

imohammad74 commented 5 years ago

I coding a Arduino's program. it worked well but after some day it break and don't send or receive data. I printed the NRF24L01 configuration and result was:

STATUS       = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0
RX_ADDR_P0-1     = 0xf0f0f0f0d2 0xf0f0f0f0e1
RX_ADDR_P2-5     = 0xc3 0xc4 0xc5 0xc6
TX_ADDR      = 0xf0f0f0f0d2
RX_PW_P0-6   = 0x20 0x20 0x00 0x00 0x00 0x00
EN_AA        = 0x3f
EN_RXADDR    = 0x02
RF_CH        = 0x4c
RF_SETUP     = 0x07
CONFIG       = 0x0f
DYNPD/FEATURE    = 0x3f 0x04
Data Rate    = 1MBPS
Model        = nRF24L01+
CRC Length   = 16 bits
PA Power     = PA_MAX

I I run a sample code "pingpair_dyn.ino" in get NRF configuration details.So compare between ttwo result "pingpair_dyn.ino"

STATUS       = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0
RX_ADDR_P0-1     = 0xf0f0f0f0e1 0xf0f0f0f0d2
RX_ADDR_P2-5     = 0xc3 0xc4 0xc5 0xc6
TX_ADDR      = 0xf0f0f0f0e1
RX_PW_P0-6   = 0x20 0x20 0x00 0x00 0x00 0x00
EN_AA        = 0x3f
EN_RXADDR    = 0x02
RF_CH        = 0x4c
RF_SETUP     = 0x07
CONFIG       = 0x0f
DYNPD/FEATURE    = 0x3f 0x04
Data Rate    = 1MBPS
Model        = nRF24L01+
CRC Length   = 16 bits
PA Power     = PA_MAX

The TX_ADDR is different in this results. how to change TX_ADDR in my program ? Thanks

Use openWritingPipe per http://tmrh20.github.io/RF24/classRF24.html#af2e409e62d49a23e372a70b904ae30e1 to change tx addr.

What's it "CONFIG"? I changed the pipes and TX_ADDR changed and corrected . But now CONFIG is difference between them. I have generally question: Should "NRF Configuration" be same at Raspberry (3b+) and Arduino Uno?

Its the hex value of the Config register of the nrf chip. See page 54 of here

Not necessarily, especially if one is in RX mode and one is in TX mode.
