[SOLVED] NRF24L01 and SDCard Conflict

Hi, I try to connect nrf24l01 and SDCard adapter to Bluepill. I use it as RX / receiver for data logger.

nrf24l01 wiring (I use SPI2) :
CE -> PA8
CSN -> PB12
SCK -> PB13
MOSI -> PB15
MISO -> PB14

and SDCard adapter (I use SPI1) :
CS -> PA4
MOSI -> PA7
SCK -> PA5
MISO -> PA6

For nrf24l01 library, I use this library :
https://github.com/spirilis/Enrf24

And for SDCard adapter, I use Greiman SDFat library :
https://github.com/greiman/SdFat

If I separate nrf24l01 and SDCard, each one of them works perfectly, and if I combine in one bluepill, nrf24l01 can’t receive message from another device..

this is my code :

#include <SPI.h> #include <Enrf24.h> #include <nRF24L01.h> #include <string.h> #include "SdFat.h"


SPIClass _SPI(2);
#define ce_nrf PA8

#define csn_nrf PB12

#define irq_nrf PA0
#define cs_sd PA4
#define lmp_hijau PA2

#define lmp_merah PA3
Enrf24 radio(ce_nrf, csn_nrf, irq_nrf);

const uint8_t node[] = { 0xF0F0F0F0E1LL };

//const uint64_t node[] = {0xF0F0F0F0E1LL, 0xF0F0F0F0E2LL};
SdFat SD;

File file;
void setup() {

Serial1.begin(9600);
_SPI.begin();

_SPI.setDataMode(SPI_MODE0);

_SPI.setBitOrder(MSBFIRST);
pinMode(lmp_hijau, OUTPUT);

pinMode(lmp_merah, OUTPUT);
Serial1.print("Initializing SD card...");

if (!SD.begin(cs_sd)) {

Serial1.println("initialization failed!");

return;

}

Serial1.println("Initializing SD card done.");
radio.setSPI(&_SPI);

radio.begin();  // Defaults 1Mbps, channel 0, max TX power

radio.setRXaddress((void*)node);

radio.enableRX();

}
void loop() {

char uid[] = "";
radio_state(radio.radioState());
while (!radio.available(true));
if (radio.read(uid))

{

Serial1.print("Received packet: ");

Serial1.println(uid);
file = SD.open("18042018.txt", FILE_WRITE);
if (file)

{

file.println(uid);

file.close();

Serial1.println("done.");

digitalWrite(lmp_hijau, HIGH);

delay(200);

digitalWrite(lmp_hijau, LOW);

}

else

{

Serial1.println("error opening file");

digitalWrite(lmp_merah, HIGH);

delay(200);

digitalWrite(lmp_merah, LOW);

}

}

}
void radio_state(uint8_t status)

{

Serial1.print("Enrf24 radio transceiver status: ");

switch (status) {

case ENRF24_STATE_NOTPRESENT:

Serial1.println("NO TRANSCEIVER PRESENT");

break;
case ENRF24_STATE_DEEPSLEEP:

Serial1.println("DEEP SLEEP <1uA power consumption");

break;
case ENRF24_STATE_IDLE:

Serial1.println("IDLE module powered up w/ oscillators running");

break;
case ENRF24_STATE_PTX:

Serial1.println("Actively Transmitting");

break;
case ENRF24_STATE_PRX:

Serial1.println("Receive Mode");

break;

default: Serial1.println("UNKNOWN STATUS CODE"); } }

Which IDE do you use? Which core do you use?
Don’t you have some warnings at compile time?

I use arduino IDE, core, sorry I don’t know, I still learning, I compile it with STLink, no error, no warning, but still not work..

@Manny , ok, I will try it..

@Manny, I change with your code, but still not work..

still same, cannot receive data :

this is what happen when I delete SDCard initialization, it works :

its strange, no error, no warning..

I also test with arduino SDCard library, but same, still not work..

Since you tried 2 different sdcard libraries with the same result, perhaps the problem is in the NRF24 library instead, trying to use the SPI object and crashing the sketch.
Try using SPI port 2 with the SDcard, and port 1 with the NRF.

Greimans SDFat latest SD Fat library let’s you use either port. I forgot how to select the port, but you can see it somewhere either in the documentation or in the sdspi code.

Alternatively you could try my SdFat fork instead of the original. I have adapted it to work with the libmaple core (I am not sure, but you may also need to use it together with my libmaple core)

I have used a SD card and a nrf24 on different SPI ports before but not that particular radio library.

You could give this one a try viewtopic.php?p=20500#p20500

before I use this library and buy SDCard module, I try any library at that thread, just to make sure the device can run, including your library, but no one can work, then I found this library and work in my bluepill. I will put the problem in that thread later.

finally I solved the problem. I don’t know what happen, maybe conflict when NRF24L01 and SDCard initialized together. Instead of initialize SDCard in setup, I initialize SDCard when needed and it works..

this final code :
#include <SPI.h> #include <Enrf24.h> #include <nRF24L01.h> #include <string.h> #include "SdFat.h"


SPIClass _SPI(2);
#define ce_nrf PA8

#define csn_nrf PB12

#define irq_nrf PA0
#define cs_sd PA4
#define lmp_hijau PA2

#define lmp_merah PA3
Enrf24 radio(ce_nrf, csn_nrf, irq_nrf);

const uint8_t node[] = { 0xF0F0F0F0E1LL };

//const uint64_t node[] = {0xF0F0F0F0E1LL, 0xF0F0F0F0E2LL};
SdFat SD(1); // This is from @Manny code

File file;
void setup() {

Serial1.begin(9600);
_SPI.begin();

_SPI.setDataMode(SPI_MODE0);

_SPI.setBitOrder(MSBFIRST);
pinMode(lmp_hijau, OUTPUT);

pinMode(lmp_merah, OUTPUT);
radio.setSPI(&_SPI);

radio.begin();  // Defaults 1Mbps, channel 0, max TX power

radio.setRXaddress((void*)node);

radio.enableRX();

}
void loop()

{

char uid[33];
radio_state(radio.radioState());
while (!radio.available(true));
if (radio.read(uid))

{

Serial1.print("Received packet: ");

Serial1.println(uid);
SD.begin(cs_sd); // Initialized sdcard when needed
file = SD.open("18042018.txt", FILE_WRITE);
if (file)

{

file.println(uid);

file.close();

Serial1.println("done.");

digitalWrite(lmp_hijau, HIGH);

delay(200);

digitalWrite(lmp_hijau, LOW);

}

else

{

Serial1.println("error opening file");

digitalWrite(lmp_merah, HIGH);

delay(200);

digitalWrite(lmp_merah, LOW);

}

}

}
void radio_state(uint8_t status)

{

Serial1.print("Enrf24 radio transceiver status: ");

switch (status) {

case ENRF24_STATE_NOTPRESENT:

Serial1.println("NO TRANSCEIVER PRESENT");

break;
case ENRF24_STATE_DEEPSLEEP:

Serial1.println("DEEP SLEEP <1uA power consumption");

break;
case ENRF24_STATE_IDLE:

Serial1.println("IDLE module powered up w/ oscillators running");

break;
case ENRF24_STATE_PTX:

Serial1.println("Actively Transmitting");

break;
case ENRF24_STATE_PRX:

Serial1.println("Receive Mode");

break;

default: Serial1.println("UNKNOWN STATUS CODE"); } }
