Radio setup give: "check wires"

[MLs]

@axillent

Four Dallas temp sensor.

But what I am interested in is the model I have (nRF24L01 + / nRF24L01) and not to send / receive data.

[axillent]

@MLs if you have original nordic you will see + for the plus version

[MLs]

@axillent

I bought them through the store available here at Mysensors

[axillent]

@MLs it should be OK
the old version is out of production for years

[MLs]

@axillent

Possible, but now I wanted to read it out of the hardware to be sure.

that is easy))) check wires

@axillent

As I wrote earlier, it is linked and I have also measured the cables to minimize errors.

[axillent]

@MLs disconnect all from arduino

connect radio as stated here http://www.mysensors.org/build/connect_radio
get example GetStarted sketch from RF24 library and see the output

it should be OK
otherwise most probably the radio is broken

But they still seem to pop up. See a bit up in the thread.

@hek you knew from our conversation last night that I also got "check wires" and was ready to think that all my modules are the old ones

but finally my issue has nothing to do with version of the chip. It is exactly "check wires" issue and issue of the conflicts with other staff,
and my modules were purchased about two years ago

is it any confirmed case with the old version?

[hek]

@axillent
Yep, if you look at the pictures above they're missing +

[axillent]

@hek you are right
but it seams that only @sonicblaze is owner of this rare thing

@axillent And me! I started the thread so I have got 10 of the them, maybe something for the MySensors museum!

hm. are the + is missing on top of the nordic chip?

it can be probably still used for mysensors in case of:

• switching data rate to 1Mbs or 2MBs (old version do not support 250Kbs - default to 1.4)
• comment out "check wires" check inside Mysensors library

[olaeke]

@axillent Yes there is no + on those.
I have tried using them but without success. I couldn't get them to work at all on the gateway but if I replaced the gateway with + variant and non + on the node then it "almost" worked. I couldn't get the "Auto Id" function to work. I think it has something with Ack to do, i will remember that I have read somewhere that the hardware ack is only implemented in the + variant.

Hello,

I'am a new one on this forum, and I've stepped on the same rake like others. So there are some recommendations for other newbies and questions for developers:

1. I've wasted some hours because this library uses serial baud rate 115200, not 9600, what is default for other projects - it should be mentioned in proper place, sorry, if it is, but I've not noticed it.

2. Next step for all users, that want to use this great project, should be sketch that outputs NRF24L01 version: my history is, that I've bought 10 NRF's from the same seller (alice***) 2-3 months ago, on chips there is "+" sign, but sketch says, that there is NRF24L01 without "+" :(

3. What to do for those unlucky, that bought wrong version: maybe it's possible to use these modules with some restrictions, while right modules will arrive? I saw recommendations about sensor node to change speed and comment out while()1) after "check cables", but what to do for gateway node?

4. I'm not a geek developer, maybe it is possible to use #define SOFTSPI in main sketch, before including other libraries? It would be simpler, than editing file RF24_config.h for gateway node and sensor node?

Thanks!

It is mentioned at a few places on the main site. Anywhere particular place it is missing?

Unfortunately the Arduino IDE build system is f**cked up and does not allow this. But I agree that DEBUG and SOFTSPI would had been great to add in the sketch itself.

I've started from "Building Ethernet Gateway" and finished on "MQTT Gateway", as I use OpenHAB as Controller.

Hm what's this? I haven't had time to test it yet, but it looks very suspicious. I'm pretty sure I ordered via MyS store on Jan 10 (soon after the Ali-links just were introduced). Is it worth the hassle to test or should I throw it straight into the garbage and order a new batch from a proven supplier (which one)?
Bought it from here.

[axillent]

@m26872 this is most probably based on a Chinese clone of the nordic chip

it could probably work
At least nobody will charge you for the try :)
