@gohan Thanks, I will try that!

We bought these: NRF24L01+ PCB Adapter

We do not use any capacitor.

What irritates me, the gateway works (ethernet gateway) with the +PA+LNA, whereas the sensor nodes do not. We have switched the PCB Adapters and antennas without any change.

@gohan I bought the voltage regulators for nrf24 and provide 5V, but still...

@Yveaux do you also use Grafana in order to visualize the data? I am not sure what fields/attributes are necessary despite "time" and "value" for a binary sensor.

It's weird, as it seems to work for my Gateway, but as soon as my sensors are connected with the +PA+LNA, they cannot register.

Thanks a lot guys. Can you recommend a suitable power supply? And what capacitator should I get?

And how does the RFM69 compare to the NRF24L01?

Thanks for your help, once again.

I have only connected it to the Nano's 3.3V port yet.
Unfortunately, I didn't know that disconnecting the antenna might damage the radio. But I did only try it with one of the radios.

How should I then connect it properly if the 3.3V is insufficient?

Thanks in advance.

Hello everyone,

I have just switched from NRF24L01+ to NRF24L01+PA+LNA radio modules and I am currently struggling with establishing a connection between the Gateway and a Sensor.

In general: With the NRF24L01+PA+LNA connected to 3V, the serial monitor remains empty from time to time (especially often if the antenna itself is disconnected from the radio module).

Also, when starting the Arduino IDE with the sensor node connected, I receive the following error message:

Error while setting serial port parameters: 115,200 N 8 1

With the NRF24L01 radio module I used before, there is no such problem. The Gateway receives and the sensor sends - as it is supposed to be.

It's really frustrating, because I wanted to enhance the signal strength and now I am left with no communication at all.

I have read that the problem might be the 3.3V supply. Does this problem match the schema?

Thanks in advance.

@mfalkvidd I can have it output in either 12V or 24V - my choice.

I have various SRD-12VDC-SL-C octocoupler relays, but I have no idea how to set it up as a sensor instead of an actuator.

@gohan see my reply to mfalkvidd

I had a look at the Power Meter Pulse Sensor but I am clueless on how to transfer it to my components.

Thanks again for taking the time to help.

@gohan thanks for your input! Can you explain how exactly you would do that? I think I should have some optocoupler in my starter kit - does it have to be some special kind of optocoupler? Can you tell me how to connect the Arduino, Octocoupler and the "machine" I want to measure? Are there mySensor sketches I could work with?

@mfalkvidd thank you too. I just had to do some research on what ttl means and unfortunately, I am not sure whether this true for our machine. Same question here, is there a sample sketch available?

Thank you very much guys. I really appreciate your support.
