They work's fine without the breakboard.

IRQ and CE should not use the same pin. Rfx docs show pin 3 for CE.

excuse me CE = 3 and CS =7

epa64 commented 9 years ago

and they dont't work

It was an error in my document.

I noticed this in device details:

Carrier board also has two 8 pin (4×2) headers for plugging in a nRF24L01+ module, one header providing connection to the hardware SPI pins D11-D13, and the other to an alternative set of pins, D4-D6, for a software SPI (“bit banging”) implementation if preferred. IRQ pin is set at D2, CE is D3 and CSN is D7.

Are you sure you are using the hardware SPI header?

You also mention you are using RF24L01+ (DEV Branch) : is that the Updates branch you are using? It incorporates the new SPI transaction API, so you may have slightly different results between that and the master branch.

The only reason there should be any difference with using the shield is incorrect or faulty connections really.

epa64 commented 9 years ago

Thank's for the reply

The nrf24 is in spi hardware pin.

I work with master nrf24 branche and nrf24Network Dev branch. I use your nrf24Mesh librari. I try with the new SPI lib for the test.

hi,

I try next with debug and printdetails. https://github.com/TMRh20/RF24/blob/master/examples/GettingStarted_HandlingData/GettingStarted_HandlingData.ino

I suprise the assembyl embeddedCoolnes board does'nt take the setup configuration and block when write.

I just modify the sample and place this if (role == 1) { radio.setDataRate(RF24_1MBPS); radio.setPALevel(RF24_PA_LOW); radio.setCRCLength(RF24_CRC_16); radio.setAutoAck(false); radio.printDetails(); // radio.stopListening(); // First, stop listening so we can talk. Serial.println(F("Now sending"));

.......... ........... }

and i obtain this result

When i try with my breadboard assembly they wok fine . The write method does'nt block.

Well, lets break this down to the basic change involved: the breakout board.

The breakout board just connects to existing pins on the Arduino and runs those connections to its own header pins.

From there, the nrf42l01 module is plugged into one of those headers.

The only thing that really changed is the physical connections, so the problem must be there. If you have a multimeter, a quick test can check for faulty connections. Also, how are you powering the device? Maybe try using the external plug instead of USB or vice-versa. This seems like more of a hardware issue than anything that I can really help with.

epa64 commented 9 years ago

Your are right,

My project (GPLV3), soon on github, consists of a MESH sensors network (tennsy 3.1 + nrf24) and a router of message on Olimex A20 with node.js nd Redis.

This project (Proof of concept) is realized for the elderly persons that must stay at home.

We received a financing by the region Aquitaine France through a promoting association free software. AQUINETIC http://www.pole-aquinetic.fr/

If you want I can send you a teensy and one board embeddedcoolness to make test.

At the moment the assemblies which work are on a breadboard.

For reason of packaging I look for assemblies to support the teensy 3.1

In every case thank you for this library and the time which dedicates you it.

PS: The tension of nrf24 is 3,24 V.(Measured in the voltmeter.)

Best regards

Eric

Ok, for sometihng like this, I can probably help. If you really want to send me hardware to troubleshoot with, email me at tmrh20@gmail.com and we can maybe arrange something.
