Sending sensor data from raspberry via NRF24L01+ to arduino
I have been looking at instructions to set up a communication system where I can send my Arduino data to a Raspberry Pi via a NRF24L01+.
I have used this link: https://www.youtube.com/watch?v=_68f-yp63ds&lc=z12wivkbyr3uzleri04ccblr3wflyntwpgk
While everything run there is no data sent or received.
If anyone could give me an advice or correction or even provide me with a new insturction link it would help !
I am planning to send ultrasonic data or a HMC5883L data to the pi.
@LaMB95 welcome to the MySensors community!
Doing that with MySensors is fairly easy. Create a gateway, either directly attached to the raspberry pi gpio pins (https://www.mysensors.org/build/raspberry ) or using a serial gateway (https://www.mysensors.org/build/serial_gateway )
An example for sending data from a ultrasound distance sensor is available at https://www.mysensors.org/build/distance
Be aware that using MySensors is VERY different from the instructions provided in the video you linked. You might want to start reading the getting started guide, https://www.mysensors.org/about
Thank you so much for getting back to me!
When you mean serial gateway is it something where the Arduino is directly connected to the pi?
I wasn't sure which code to implement on the Arduino to send the sensor data.
What I need is a code from the Arduino to send the data from an ultrasonic sensor to a database (or something) on the pi using the NRF modules.
I have been working on the installation of the libraries.
I have Added them to the Arduino ide software but when I run the gateway serial code it shows that
fatal error: MySensors.h: No such file or directory
What is causing this?
PS I am using a Macbook
@LaMB95 seems like the MySensors library isn't installed. Did you follow the instructions on https://www.mysensors.org/about/arduino#installing-the-sensor-libraries ? If so, did you get any error messages?
I'm doing a project very similar to yours. Mysensors library can be installed from library manager in arduino ide, just like many other libraries.
Just resolved the issue !
Apparently my Arduino Ide wasnt updated to the lastest version which explains why I never found the Library Manager
Great that you found the problem @LaMB95, thanks for reporting back. It might help someone else in the future if they have the same problem
However I am still facing some issues trying to set up a gateway with the raspberry pi,
Do you know who could help me with that ?
@LaMB95 just create a new thread describing what you have done, what result you got and what result you expected and we'll help.
I'm having problems exactly the same as @LaMB95
The MySensors library is installed, at least is says so doing as shown in the link @mfalkvidd sent.
This is my error:
DallasTemperatureSensor.ino:36:25: fatal error: MySensors.h: No such file or directory
Okay could you check what version of Arduino IDE you have now ?
If there is a newer version upgrade to that.
My issue was that I could not find the library manager in the version I had.
Hope it helps !
You don't have the mysensors library installed
I'll have to get back to you later on that.
The software says it's installed. Is there a way to uninstall and install again?
from library manager you can install, remove, update the libraries. You can try to remove from the Arduino IDE and try to copy the library manually where you have all the libraries
Sorry for the delay, my IDE is 1.6.5 going to try and update.
Thanks in advance.
Got it working, IDE updated and everything working.
My temperature already getting values.
Going to try and attached another DS18B20 as shown in the example.
Don´t really know what is going to show up.
Just change the node ID and you shouldn't have any problem
I am facing an issue while sending data from an Arduino pro mini 5V to an arduino UNO. Receiving a lot of garbage from the Pro mini.
Any idea why ?
