Radio setup give: "check wires"

[axillent]

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

[olaeke]

@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 :)

[slarti]

@m26872 Didn't work for me. Please tell me how you do.

[axillent]

@slarti start from the RF24 example named GettingStarted
connect wires according to hek's instruction http://www.mysensors.org/build/connect_radio

[slarti]

@axillent I tried it and it worked with the modules but none of the MySensors example sketches work with them. Thread about it.

[axillent]

@slarti what is the output from printDetails ?

is your chip recognized as NRF24L01+ or just NRF24L01?

[slarti]

@axillent That's the funny thing, they were recognized as NRF24L01+ but still refuse to work. I don't get "check wires". I just don't get anything.

[axillent]

@slarti getting nothing is already something)

GettingStarted can be used to connect two arduinos. Have you tested this? You told that examples are working.

[hek]

Might be possible to tweak initialization to get them to work. If someone has too much time on their hands this could be added as a new RFM73 driver in the development branch.

http://forum.mysensors.org/topic/300/rfm73-experience/14

[slarti]

@axillent Yes, the pingpong sketch from @olaeke works after I import the MySensors library to the sketch and comment out
//#include "nRF24L01.h" //#include "RF24.h"
and
#define MINIMAL from RF24_config.h

None of the "normal" examples work or give anything over serial.

[axillent]

@slarti it is probably a limited set of configurable parameters are allowed for your chip

you can investigate this but no success guaranteed

[slarti]

We'll know tomorrow or the day after as I found a Finnish guy with some radios that should be either the real thing or the SI24R1 -clone that should work.

[m26872]

Thank you for the info. I never inteded to develop any driver so I will simply buy a new batch with more care this time.
