💬 NRF2RFM69

On NRF24 CSN is equivalent of CE signal on the SPI bus. While CE is a global on/off switch for the TX/RX on the NRF (Check page 11 in the nrf24 datasheet

On RFM69 CE is actually called NSS (pin 15). Datasheet are here

I don't have the schematics of this project at hand right now, as someone has forgotten to add a pdf of it to the repository ;)

gohan

I haven't mapped all the pins because yesterday I was a little tired, maybe tonight I'll check, but the fact is that I can't initialize the radio while the nrf24 works. 😕

tbowmo

I have used the board with a couple of sensebender micros.. and they worked fine..

gohan

Looking at the https://www.mysensors.org/build/raspberry page I have the current mapping on the board rfm69 side:

pin above DI00 is connected to CE pin
DI00 is connected to IRQ
NSS is connected to CSN
MOSI to MOSI ok
MISO to MISO ok
SCK to SCK ok

Do you think is correct?

tbowmo

RFM69 NSS is equivalent of NRF24 CSN

DIO0 act as interrupt line, and is attached in accordance with connecting the radio.

the pin above DIO0 is actually the reset line for the RFM69 module.. Which might come in handy, if you want to do a hardware reset at some point in time :)

gohan

So why isn't it working then? Did I fry the radio?

tbowmo

@gohan

Could you have added it to a 5V arduino? RFM is not 5V tolerant, so that could fry the radio..

gohan

No, I used it only on the raspberry

gohan

New update: I used the module on the EasyPCB, nrf24 version, from @sundberg84 and recompiled the sketch to use the rfm69 and it is able to initialize the radio. So there must be something wrong with the compiled gateway on the RPI as it should be a direct swap from a NRF24. I am moving to the RPI thread

PS Now it seems to be working... I haven't changed anything.... must have been a bad connection then

Hi all,
which size of cap should be used on this board and is it possible to connect a SMA Antenna ?

Many thanks

Markus

tbowmo

use a 4.7uF capacitor, or there about..

There is no pads for a SMA connector, but you could attach one with a pigtail..

Markus.

@tbowmo Thanks for the Information... One stupid question about the SMA conenctor :-) Is it enough to connect only the Antenna Output conenction or must GND also conencted...?

gohan

You can just solder the antenna only on pcb. I use a coil spring type

Markus.

just one more question... I have on the Gateway a RFM69HW and a node with a RFM69W module. In the Gateway Sketch is the HW type enabled

#define MY_RFM69_FREQUENCY RF69_868MHZ
#define MY_IS_RFM69HW

But there is no comunication from the node... I use Mysensors 2.1.1.
Any idea?

gohan

What gateway is that? I'd suggest to try mysensors 2.2 development

Markus.

@gohan It at the Moment only a test. So I have one EasyPCB NRF board with FTDI as Gateway and another EasyPCB board with DHT22 Sensor attached as Node. On both is a 4,7uF electrolytic condensator attached Close to the NRF socket. Both boards are at the Moment with RFM69W 868. The sensor node is battey powered.

gohan

Get latest 2.2 library and use new rfm69 driver. Did you remember to close the IRQ contact in the easypcb?

Markus.

@gohan Oh Sh* must check this... I've tried it yesterday on both devices the 2.2 Dev. But will Keep ypu informed...
Don't find the jumperfor the IRQ on the Rev 9 board. can you please post a Picture. Seems that this one is definitly not closed...
--> Edit... found it in the documentation but still the same.
Think the next Point to check for me are the antennas... :-(

gohan

I'd suggest to buy the coil spring antennas for your frequency, they are cheap and compact.

Markus.

in principle there is traffic between node and Gateway..
