check wires

5 years 4 months ago #516 by HarryDutch
I'm using EasyIoT server 6 on a Raspberry Pi B+ and have no problems with the ESP8266 part. But as soon as want to enable the MySensors driver nothing happens when I hit the ebable button. In the server console I see the message "check wires". I have checked the wiring from the NRF24L01 to the PI and it is exactly the same as described on this site. The NRF24L01 is not faulty. Tried several of these modules. Still the same problem. Any idea how to solve this?

That's about the new version 2. I'm using the B+.

Raspberry pi B+ have more pins than the earlier models.
I had the same problem until I discovered that.
So compare pinlayout between raspberry pi B and B+, and you will se a difference.
I have on the other hand problem to get the esp8266 work. :)

You're right about the pin layout, but the pins that are being used to connect the NRF24L01 are the same for the B and the B+.

I replaced the jumper wires from the module to the pi and put a 10uF across VCC and GND on both modules. It's now working but there are still some problems with the IoT server. It seems to freeze from time to time (beta 7).

ESP8266: Have you tried to change the default port? (In Esp8266EasyIoTConfig.h). As soon as I used port 8080 ( not blocked by my firewall) it worked as it should.

Yes, adding additional capacitor to VCC and GND on NRF24L01 is recommend.

When do you experience that EasyIoT server fezzes?
