Radio setup give: "check wires"

kalle

Please show us a picture of wiring on the radio chip. The radio wiring at the nano (color) looks ok.
Maybe you can test a other sketch (temperature).

Here is radio wiring

I don't think another sketch will help since i stop on:

  gw.begin(incomingMessage, AUTO, true);

And this calls setupRadio which look like this:
.....

 RF24::begin();
 if (!RF24::isPVariant()) {
    debug(PSTR("check wires\n"));
    while(1);
 }

...
So it stops because it is not pVariant. BUT since I have bought the radio on MySenors link and it says on ebay that it is a NRF24L01+ i will strongly belive that it is a + variant.

It could be bad wires. Have your tried replacing or testing connectivity with a multimeter?

olaeke

Yes every wire is "beeped"

hek

What kind of cap are you using on the breadboard? Tried without it?

I have radios confirmed working. Maybe I could send you one?

@olaeke

The wiring "howto" on the mysensor page, is using a ARduino mini, not a nano.

Have you tried to verify the connections on schematic level for the two arduino versions? (ie. check that the different pin numbers match up to the same pin names on the atmel on the two boards)

If I remember correctly there might be some differences. (I'm using a nano on my GW, and mini's on sensor nodes.)

@hek: The cap. is a electrolyt on 4.7uF so it should be Ok but i will try to remove it or decrease it to 1uF.

@tbowmo: Is far as I can se on all spec. pages it looks like the pinout for SCK (13), MOSI (11) and MISO (12) is the same on Mini and Nano. Chip enabled and Chip select is not so critical since it is configurable in MyConfig_h but I use the default 9 and 10 for this. For The IRQ line I use #2 (INT0). IRQ line is same in Mini and Nano.

Interesting...I just registered because I'm having the same issue with a Arduino Pro Mini 5v. Checked wires, I've ripped it apart and rewired it multiple times, checked voltages at the radio to make sure my 5v -> 3.3v stepdown is working proper, checked continuity all the way from the radio pins to the actual SMD atmega chip itself, tried 6 different radio chips, and everything seems proper.

Just curious, when did you buy your radio chip, and was it from Alice1101983? I bought mine via the MySensors link as well on Nov. 27th. Bought 10 chips, tried 6 so far and stopped there to start asking for help...

sonicblaze

Hmm...If i look very closely at my radio chip, I can read the writing. and I see '24L01' in the middle, but google images found chips that say '24L01+', which is what I supposedly bought.

@olaeke: Can you read whats on your chip?

Can someone with a working radio look at your onboard smd chip and tell us if it says '24L01+' on it?

hek

Could you perhaps contact Alice1101983 and ask if they have changed supplier recently?

A photo of your NRF-chip and full board makes it easier to compare.

olaeke

Yes I bought my radios from MySensors link and I ordered them sometimes at the end of November. I will look at my chip tonight and come back.

hek

I'll contact the ebay-seller and ask some questions...

sonicblaze

This is my supposed 24L01+ radio from Alice. I'll shoot the eBay seller a question, I'm guessing that chip should say '24L01+', not '24L01' :smile:

hek

Just a thought... What happens if you remove the sanity check if-statment here:

Guessing this really isn't the plus version, we'd also have to change the datarate in MyConfig.h. The data rate is defaulted to 250kbps, which is the new long range mode only supported by the + version from my understanding.

Ok; I commented out that if check, and it doesnt throw the check wires debug anymore, but I still can't include my sensor and I was within 5 feet of my gateway. I tried changing the datarate, but then thought my gateway is also at 250kbps, so I'd have to reprogram that as well, and stopped there for now. I did look at my gateways antenna version of the nfl2401+, and it's chip does have the + sign, so these other radios are definitely not the right ones. I sent a message to the eBay seller.

@olaeke: Hopefully this is your problem too (wrong radio chip)

This is what one of my NRF24 modules look like:

I think I got them from some random AliExpress seller. So yes, it would seem some sellers started shipping old stock or something.

And yes, this pcb is dirty as hell, and with residue from flux etc.

RJ_Make

I can also confirm my chips..

olaeke

@sonicblaze: Yes my radio as also without the + sign, but my antenna version is with the + sign, however I haven't have time to test this yet. I order them both at the same time from alice..... and I will also contact them now.

Is it the same pinout on the antenna version since there is not printing on that board?

sonicblaze

@olaeke I sent a message to Alice as well, I'll let you know if I hear anything. I also went on AliExpress and just ordered a pack of 10 off of there for $7.28, so hopefully I'll get proper radios one way or another...

I've never seen any documentation that suggests the pinout is any different between the two versions. It's the same everything except an external antenna instead if on-board.

olaeke

Just tried to find a way to concat "alice.." on ebay but whatever link I click on I end up on "You have to Contact seller trought paypal.."

Shit so then it ends up in a new order and another 3 weeks wait for new delivery! And I also don't get my Vera as I have order 5 weeks ago so it turns out to be kind of failure with my homeautomation christmas holiday.

No luck with Santa this year
