This would mean in a one-way set-up my transmitter should have MOSI high and receiver should have MISO high.

MISO indicates data transmitted from the nRF24L01 (slave) to the microcontroller (master) - i.e.

MOSI indicates data transmitted from the microcontroller (master) to nRF24L01 (slave) - i.e.

I just thought I'd add in regards to the two comments.įirstly in response to srnet with regards to SPI, my understand under the nRF24L01 configuration usage: If you are new to nRF24s it may be better to start with a pair of low power modules with the pcb antenna. However someone on the Forum has had them working without that separation - I don't have any personal experience with them. If you are using the high-power nRF24s (with the external antenna) it may help to have a distance of about 3 metres between the two nRF24s so that the signal does not overwhelm the receiver. At least for testing try powering the nRF24 with a pair of AA alkaline cells (3v) with the battery GND connected to the Arduino GND. The high-power nRF24s (with the external antenna) will definitely need an external power supply. This seems to be a particular problem with the nano.

There is also a connection test program to check that the Arduino can talk to the nRF24 it is connected to.Ī common problem with nRF24 modules is insufficient 3.3v current from the Arduino 3.3v pin. Start by getting the first example to work

If you get stuck it will be easier to help with code that I am familiar with.

The examples are as simple as I could make them and they have worked for other Forum members. Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features. Have a look at this Simple nRF24L01+ Tutorial. One thing I'd be particularly keen to know is if there is a way to check if a message has even been sent or can even be sent based on a function call or diagnostics as at the moment either something is wrong in the code that I can't see or I am erring on the side of hardware damage.Īdditionally are there any hardware-specific code adaptions needed to implement on the hardware I am using. like the ping pong getting started example. I've tried to minimise power consumption through settings and be very specific about communication channels/addresses (having tried being minimalist with the default settings and not getting anywhere), yet still, I can't communicate between the two, and I've tried countless examples, i.e. Power through the Arduino 5V pin with the module base having a voltage regulator and capacitors Power through a voltage regulator from x2 Li-ion batteries with x2 10 uF capacitors pre and post regulator

The transmitter is using the connections: I have noticed however that both modules seem to have the MOSI pin high and MISO low, despite one being in receive and one in transmit, I might be wrong but the transmitter should have the MOSI high and receiver MISO high for the SPI protocol. I have done a pin-out with a voltmeter to validate connections, and know the RF24 modules are getting 3.3 V to 3.6 V at over 150 mA (max just shy of 200 mA).

I have a transmitter running on an Arduino Pro Mini (based on ) and receiver on the Arduino Mega 2560 Rev3 through a module base.

To keep things compact I've attached the codes and Serial Output. I'm having issues with two RF24 modules (NRF24L01+PA+LNA versions) and hoping to get some feedback with regards to diagnostic messages (in particular what the STATUS elements of printDetails should be or means) or tests I can do.
