Issues with setting up my Arduino Nano SerialGateway

[Christian Simonsen]

In case it was something wrong with the Arduino Nano, I've replaced it and tried another. However Im still getting the same error. "0;0;3;0;9;radio init fail".

@Christian-Simonsen

I have now also tried the long-range version (link) and Im getting the same error. "0;0;3;0;9;radio init fail"

@Christian-Simonsen

I've also tried to switch the MISO and MOSI just in case I had got it wrong. No effect. Still the same error.. :( Running out of ideas...

@Christian-Simonsen what is the log saying when you monitor the gateway with serial monitor?

also query this forum for St0;0;3;0;9;radio init fail. It might help you.

@Christian-Simonsen most have been said above, but my thoughts:

Radio init fail means

1. Not wired correctly
2. Not powered correctly
3. Not a nrf24 with +

Do you have a capacitor between grn/vcc on the 3.3v radio? This can make difference...

Some reading regarding + and not + Nrf modules.

@sundberg84

The chip marking is "NRF M 24L01+ 1452AB" - so I assume it is a + module.

I've tried to rewire it multiple times, I will try again.

[sundberg84]

@Christian-Simonsen - Markings is not a guarantee...
See the threads i posted, there are alot if images.. maybe you can see something there. Or post a picture of your radios here... maybe we can spot something if you suspect its a fake.

Also - how do you power your node?

[TheoL]

I'm using both NRF24L01 and NRF24L01+. You have to change the datarate in the MyConfig to 1mb to be able to do that.

#define RF24_DATARATE RF24_1MBPS

@sundberg84

Fake NRF chips seems like the most plausible reason so far. The chips do look of bad quality.... but whether the chips are the issues or not is difficult to say..

Can you judge from the pictures?

[sundberg84]

No - its not possible to say exacly. Its defenetly a fake - but how bad, not possible to say.
I read some days ago someone recieved a bad batch and there was no silkscreen / white markings just like you. (See image)
but I also recieved a batch yesterday without markings - and the one i used today worked great!

[Christian Simonsen]

Ok,

Is there a sketch that I can use that I can use to test/debug the NRF module specifically that might help identify what I am doing wrong or the if the module is bad?

I see some refer to running "Get Started".... but can't seem to find out what they are referring to...

[Christian Simonsen]

Hi,

I found the TMRh20/RF24 library on GitHub and I uploaded the GetStarted sketch to the Arduino. Not sure if it is working but atleast a lot started happening in the Serial Monitor.

Then I pressed "T" in the Serial Monitor and then this happend:

To me it seems to work..

Hi,

Now I have also tried the original RF24 library by ManiacBug (link). And I got this results in the Serial Terminal.

STATUS		 = 0x00 RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=0 TX_FULL=0
RX_ADDR_P0-1	x00 = 0x0000000000 0x0000000000
RX_ADDR_P2-5	x00 = 0x00 0x00 0x00 0x00
TX_ADDR		 = 0x0000000000
RX_PW_P0-6	x00 = 0x00 0x00 0x00 0x00 0x00 0x00
EN_AA		 = 0x00
EN_RXADDR	x00 = 0x00
RF_CH		 = 0x00
RF_SETUP	x00 = 0x00
CONFIG		 = 0x00
DYNPD/FEATURE	x00 = 0x00 0x00
Data Rate	 = 1MBPS
Model		 = nRF24L01
CRC Length	 = Disabled
PA Power	 = PA_MIN

From what I can understand the Arduino is able to send and receive responses (even though I only have one NRFmodule running... so not sure what is given the response to the NRF... )

Now sending 55497...ok...Got response 4294967295, round-trip delay: 55499

Now sending 63695...ok...Got response 4294967295, round-trip delay: 63711

On in the other mode I'm getting this...

The odd part is, why do I then not get the MySensor SerialGateway sketch to work... any thoughts?

[naviathan]

This isn't working at all. First, yes you have fake chips, I have the same ones, but they work with the RF24 library just fine so far. Second, the payload should be either the current microseconds or a steadily incrementing number. The payload you're getting is the result of either bad power or incorrect pin out to your controller, usually the CE and CSN are wrong.
