💬 MySensors Nrf24/RFM Serial/Ethernet GW Shield (for Uno)

[Nick Willis]

Oops fixed it by remelting all the solder joints on the mini regulators. So will cut the pin headers and hard wire for a serial gateway (which I'm starting to think is a good idea anyway to keep down system latency of going via ethernet).

@Nick-Willis - great to hear.
By using dupont cables and "normal pinout" for RFM radio i now also get the new driver to work thanks to your input.

• Continuity on all logic level converters are OK
• Not much traffic at all from the UNO in SPI. I guess the intial contact with the radio is faulty so thats why.

It must be either connection Uno > Logic Level Shifter > Radio, code / defines or softwareSPI not working.

[sundberg84]

I have now tested all SPI lines and its logic level converter individually.
To be absolutely sure the hardware worked, I desoldered the radio and wrote a arduino program sending 5v in 5 sek over the same sofwareSPI lines and 0V over 5 sek - all behaved correctly, 3.3v and 0V.

I also swapped radio, but same same...

Not really sure how to proceed. I need to get the softwareSPI working or else I cant use it as a ethernet gateway.

Is there someone here that got RFM gateway working with softwareSPI?
I dont think its the hardware anymore...

What im noticing is that when I connect the radio, the IRQ line on D2 is 1.0v when high and not 3.3v. Anyone who knows this is normal behaviour? Same with two different (and comfirmed working) radios. SPI logic level converter is comfirmed working and changed with same behavoir.

Edit > This is the same using normal pins and does not have anything to do with SPI. It works when not using softSPI and IRQ has this low voltage...

[sundberg84]

Anyone good with SPI channel analysis?

Hardware SPI (Looks great):

Software SPI (Same setup, just changed code and pins).

In the first, I can clearly see MOSI and MISO communicating on 5/6. Enable on 7.
Software SPI does not make any sense.

@sundberg84 Hello, coming back to this RFM GW, so i will try it

I have soldered between the two 3.3v rails , i confirm now i have 3.3v on the RFM module

I will test with the softwareSPIs and report.

I will give a try to your "quickfix" for hardwire : could you please explain or post a photo of what needs to be done for the hardwiring ?

Thank you!

[sundberg84]

@hlehoux My quickfix means you cant use the ethernet shield.
All I did was solder with wires to the normal pins and made it a serial gateway.

[hlehoux]

@sundberg84 thank you.

i have ordered the components such as BSS138 so i will test when they arrive.I don't need ethernet

[hlehoux]

Hello, i'm making some progress; received the components this week.

Unfortunately it doesn't work... yet
For now i have SanityCheck failure in to logs.

I'm afraid my soldering of all these little components is not good. I tested with a multimeter the 4 pins and i have continuity on one of them but maybe not the others so i guess i will have to try remelting all these small regulators ???
