3. NRF24L01 with Arduino Pro Mini at 1Mhz

NRF24L01 with Arduino Pro Mini at 1Mhz

  • Snyfir

    Hello,

    When i use my arduino pro mini 3.3V at 8Mhz everything works fine.
    But after changing the fuses of my arduino to 1Mhz, the communication between the arduino and the gateway is note working:

    My code:

    #define MY_DEBUG
#define MY_BAUD_RATE (9600ul)
#define MY_RF24_SPI_SPEED (1000000ul)
#define MY_RADIO_RF24

#include <MySensors.h>

#define DOOR_ID 0
#define DOOR_PIN 2

MyMessage msg(DOOR_ID, V_TRIPPED);

void setup()
{
  pinMode(DOOR_PIN, INPUT);
}

void presentation()
{
  sendSketchInfo("Door 2", "1.4");
  present(DOOR_ID, S_DOOR);
}

void loop()
{
  uint8_t value;
  static uint8_t sentValue = 2;
  
  delay(50);
  value = digitalRead(DOOR_PIN);

  if (value != sentValue) {
    send(msg.set(value == HIGH));
    sentValue = value;
  }

  sleep(DOOR_PIN - 2, CHANGE, 0);
}

    My fuses settings:

    ## Arduino Pro or Pro Mini (1.8V, 1 MHz) w/ ATmega328
## --------------------------------------------------
pro.menu.cpu.1MHzatmega328=ATmega328 (1.8V, 1 MHz)

pro.menu.cpu.1MHzatmega328.build.mcu=atmega328p
pro.menu.cpu.1MHzatmega328.build.f_cpu=1000000L

    I don't know why when my arduino is at 1Mhz the nrf24l01 is not working. When i put back my arduino to 8Mhz every thing works fine.

    Do you have any idea ?

    Thank you for your help

    @snyfir are you using the same power supply and capacitors in both cases?
    What does the gateway log say?

    Yes i use the same board. My gateway log (in debug) say that i received nothing.

    @snyfir could you see if defining MY_DEBUG_VERBOSE_RF24 before including MySensors.h can give a clue to what's going wrong? Comparing the output for 8mhz and 1mhz might show a difference.

    we have for the 1Mhz:

    RF24:RBR:REG=23,VAL=1

    and for the 8Mhz:

    @snyfir nice work.

    I think REG=23 is in decimal, which means register 0x17 which is RF24_REG_FIFO_STATUS.

    I checked the datasheet and it seems like value 1 means that the RX buffer is empty. Value 17 means TX buffer is empty and RX buffer is empty. That doesn't say me much though.

    Maybe @tekka can confirm if the debug output registers are in decimal, and chip in what could be causing the problem?

    The data is not send because VAL=1 means TX_FIFO not empty.
    Maybe the flag to trigger the send data is not emit in the right time ?

    @snyfir Can you run the same tests using the latest release, i.e. 2.3.1?

    It's working ! 🕺 😃
    Thanks you very much @tekka and @mfalkvidd 👍
