Yes, there is a open topic on the forum "dual spi radio", I have them both running on my RPI

Hello @gohan !
I'm trying to move on that way.
You have installed boh radios on RPi. Was a Level Converter required?

Thanks!

NO level converter since RPI is 3.3v but I had tu use sockets with voltage regulators for the radios because I used the high power versions

You mean the RFM69HW ?
Ok, in that case it's not the own I have, so I expect to connect both radios directly on the board (as soon I get one ;) )

@gohan hello again!
I’m testing the RFM69 on RPi and seems working well. The only doubt is about the range. Seems previous Arduino-RFM69-serial setup was better. Maybe only placed better.
Btw I’m thinking to increase the range using the RFM69HW version.

Is the HW the better version that is using more power?

What have you done for connect it then on the RPi?

Actually I’m using RFM69H(not W). If all are 868Mhz, are they compatible with HW version?

If all will work stable, I’ll migrate the nRF24L01+ as well. What have you done for handle power on this? On my Arduino I’m using a capacitor, nothing more.

Thanks for you help as always!!

HW version is just a regular W version with an extra power amplifier on the TX side. To use them i got some of those nrf24 sockets with voltage regulator and I soldered the radio module on the nrf2rfm pcb adapter that you can find on openhardware.io

If the "HW" version has an amplifier on the TX side, do you think it's enough to have coverage gain on nodes that are only "W"?

I cannot find the nrf24 sockets with voltage regulator on openhardware.io :-(
Do you apply it on both radios?

[gohan]

I am just referring to this https://www.mysensors.org/hardware/nrf2rfm69

The sockets you can find them on gearbest or aliexpress.

Of course the coverage gain is only within HW, but you can have closer nodes using normal W version.

Ok, you use this adapter to place the RFM69 module on it and let it fit in something like that?

Then I could wire it as always or should it use the 5V in the RPi instead?

[gohan]

If you use that you will need to use the 5V because it has a regulator built in
