with this fix, everything work fine

When reception is not working, the status register value is 0x40, so RX_DR stay set.
I think the clear of RX_DR is not working very well. i will try to add

RF24_setStatus(_BV(RF24_RX_DR))

at the end of RF24_irqHandler function

I have an arduino pro mini 5V connected to an nrf24l01+

my code is

#define MY_DEBUG
#define MY_RADIO_RF24
#define MY_RX_MESSAGE_BUFFER_FEATURE
#define MY_RF24_IRQ_PIN (2)
#define MY_REPEATER_FEATURE

#include <MySensors.h>

MyMessage msg(0, V_CUSTOM);

void setup()
{
}

void presentation()
{
	sendSketchInfo("Test", "1.0");
	present(0,  S_CUSTOM);
}

void loop()
{
}

void receive(const MyMessage &myMsg)
{
	if (myMsg.type == V_CUSTOM && myMsg.sensor == 0) {
		send(msg.set(F("pong")));
	}
}

i send every minute a message to the node. But after some time the node is not responding.
When i check the IRQ pin in the arduino (pin 2) and the nrf24l01+, this one is low. It means the nrf24l01+ has been received the last message but the interrupt has not been trigger.

How can i fix this issue ? do you have a clue ?

Thank you for your help

I want to use a switching regulator ta avoid too lost of current and heat (12v to 3.3V). A LC filter can solve my issue ?

Yes two first modules are switching regulator an the third is linear.
Nrf24l01+ are not compatible with switching regulator ?

Hello everybody,

When i powered nrf24l01+ with this module or this one the nrf24l01+ is not working (unable to send / received).
But if i use https://www.ebay.com/itm/200960749614 the same nrf24l01+ works perfectly.
All regulator deliver 3.3V so i don't know why it doesn't work. The input DC is 12V for all

Do you have a clue ?
Thank you for your help.

Hello @Mathea90, i have exactly the same issue. Do you find something to fix this issue?

@yveaux said in Gateway with signing = low memory:

#define MY_RX_MESSAGE_BUFFER_SIZE (10)

thank you @Yveaux et @mfalkvidd

I had the same result but when i add the two lines:

#define MY_RX_MESSAGE_BUFFER_FEATURE
#define MY_RF24_IRQ_PIN (2)

i have

Sketch uses 16296 bytes (50%) of program storage space. Maximum is 32256 bytes.
Global variables use 1693 bytes (82%) of dynamic memory, leaving 355 bytes for local variables. Maximum is 2048 bytes.
Low memory available, stability problems may occur.

A gateway without MY_RX_MESSAGE_BUFFER_FEATURE defined, can be problematic non ?

@mfalkvidd
So my only solution is to use an arduino with more memory ? do you have an exemple of arduino board i can use ?
