Hello Gordon,
you rock!! I've review the wiring in this particular part and now it works great for me! I'm now able to plug the NRF24L01+ in on my Espruino with a bunch of female-to-female-wires.
One additional question: What are your experiences with range of NRF24L01+? How can you increase it?
Thank you very much,
Stefan
The correct wiring:
NRF24L01+ Name Espruino Type 1 GND GND GND 2 3.3V 3.3 3.3v 3 CE A0 GPIO Out 4 CSN A1 GPIO Out 5 SCK B3 SPI SCK 6 MOSI B5 SPI MOSI 7 MISO B4 SPI MISO 8 IRQ unused GPIO In -
Hello everybody,
the tutorial on "NRF24L01+" is not working for me:
http://www.espruino.com/NRF24L01PIt's driving me crazy, because I always get the following message on the master:
>nrf.sendCommand("1+2", function(r) { print("=="+r); }); TX not received 255 TX not received 255 TX not received 255 =undefinedAny suggestion are welcomed very much, as I need an working NRF24L01+ for a futur project!
Thank you very much,
Stefan

Good joke :-) we've got a female model ...
The temperatur sensor is integrated in the baby's bed, so the little one can sleep peacefully. -
Thanks for your feedback!
I've integrated the 32,768KHz quarz crystal in the code (newer version of the code). I use this for logging purpose. The reason why I'm logging via bluetooth is the easy integration and my love to the command line :-) and the bidirectional communication. You see how flexible the espruino is, because I could also log to a SDHC-card...
The signal has a range of around 10 to 15 meters, so enough for my flat.

Hi everyone,
as we have got a newborn, I've turned the Espruino in a intelligent temperatur sensor, which monitors the Babies temperature. If it exceeds a value of 37.5 degree Celsius, a visual and acoustic warning signal starts and helps the parents to prevent the baby from overheating.
The tutrial is in German, but on the side, a translation function is integrated:
I hope, that this is useful for others here.
Stefan
Thank you Gordon! I'll try it out!
