[solved] RFM69 based nodes unable to report Lib Version

[Anticimex]

@jpaulin thanks for testing. The change should have little effect for people using signing. The issue is for people who does not use it as the node did not wait for a gw response in that case.

[korttoma]

tried the latest development branch on my test system and the results are good so far. Now I just need to update my "real" system also. Thanks to everyone that participated in solving this!!

[korttoma]

Updated now also 2 nodes in my "real" system and both now successfully reported Lib version. I did not update the GW. Maybe it is safe to say that the Lib reporting problem is solved now.

Now I will try to look in to the sofSerial RFM69 solution that @scalz is working on, do you have any eta on when you will try to include our solution in the official MySensors development branch?
Any recommendations for the wiring of an W5100/RFM69 Gateway?

[scalz]

i have removed my stuff for the moment..
for integration in mysensors, it's coreteam work in progress, thx to @Tekka ;)
Once, someone smart told me that 1+1=3, quite true :) and with Tekka i think we can say = 4 ahah
So for an eta.., i prefer not saying anything lol, just i'm back on this for the week, i was playing with other stuff..

[jpaulin]

@korttoma I have an up and running RFM69 GW with W5100 (actually a W5500, but it's the same). I'm not using softSerial in my setup. With this it is possible to integrate with eg. Moteino or Anarduino, which comes with the radio chip preinstalled on the Arduino compatible boards. But a standard arduino with a separate chip would work as well (lower price). The GW-RFM69 has been stable and flawless, as far as I can see, for quite some time. The SPI for the RFM69 and W5500 uses the following pins in my setup.

RFM69W:

• SCK = 13
• MISO = 12
• MOSI = 11
• CS = 10
• IRQ = 2

W5500:

• SCK = 13
• MISO = 12
• MOSI = 11
• CS = 7

I'll try to share wire diagrams and software setup later. I had to do some tweakings in the ethernet.h file to make it work.

[korttoma]

@jpaulin I am very interested in your solution. Could it work with a normal Arduino Pro mini 3,3V version? Just so that I know if I need to order some parts or can work with what I have.

[jpaulin]

@korttoma
Yes, it should work with an Arduino Pro Mini 3.3V. Personally I'm using for the moment an Anarduino. But it's almost the same.

[jpaulin]

@korttoma
My RFM69 - Ethernet - GW has the following setup.

On the RFM69 radio I'm using D10 as CS pin (Chip Select). This is because in my case the RFM69 radio is hard-wired to pin D10, as with eg. a Moteino or Anarduino. But this is not mandatory. If you use an Arduino Pro Mini you could select another pin for the RFM69 CS-pin on the Arduino, if you want.

The Ethernet W5100 uses the Arduino IDE pre-installed library Ethernet.h. In the library the CS-pin is as well fixed to D10. CS of course has to be unique for each SPI slave device. I changed directly in the Ethenet.h library the CS pin to be D7. But D9, D8 or some other pin is ok to use as well.

Take care, if none of your SPI Slave devices (radio and W5100) uses D10 as CS-pin. In this case make sure to set the D10 pin to OUTPUT in your sketch to keep the Arduino as SPI Master. On the ATmega328 the D10 pin is hard-wired to be the SS pin (Slave Select). The Arduino has to always be the SPI Master and the devices SPI Slaves on the SPI bus to get everything to work.

Another consideration is:
The RFM69 radio uses the SPI functions during the interrupt sequence (Pin D2). The Ethernet.h library won't work correctly if another device uses SPI signalling during an interrupt sequence. The fix I'm using is to block interrupts from the radio-unit during SPI usage of the W5100 unit. I haven't seen any flaws with this fix so far. I've found other people on the internet using the same fix too without issues.

To use RFM69 CS=D10 pin and W5100 CS=D9 pin do the following change in the W5100.h that is part of the Ethernet library.
If you use a Windows computer you'll find the file here:

C:\Program Files (x86)\Arduino\libraries\Ethernet\src\utility\w5100.h

Look for the following lines at the end of the file.

#else
  inline static void initSS()    { DDRB  |=  _BV(2); };
  inline static void setSS()     { PORTB &= ~_BV(2); };
  inline static void resetSS()   { PORTB |=  _BV(2); };
#endif

If you use D9 as CS pin for the W5100 module change as follows:

#else
  inline static void initSS()    { DDRB  |=  _BV(1); };
  inline static void setSS()     { cli(); PORTB &= ~_BV(1); };
  inline static void resetSS()   { PORTB |=  _BV(1); sei(); };
#endif

If you uses, as I do, D7 as CS pin then change as follows:

#else
  inline static void initSS()    { DDRD  |=  _BV(7); };
  inline static void setSS()     { cli(); PORTD &= ~_BV(7); };
  inline static void resetSS()   { PORTD |=  _BV(7); sei(); };
#endif

If you want to keep D10 for the W5100 just add the cli(); and sei(); macros. (cli = clear interrupt. sei = set interrupt).

If you want to use another SPI CS pin than D10 on the RFM69 radio (eg. D9) it should be safe to modify it directly in the sketch with the preprocessor constant:

#define MY_RF69_SPI_CS 9

For the MOSI, MISO and SCK pins use as mentioned above, they are as well hard-wired in the ATmega328 chip to D11,D12 and D13.

If you have any doubts please let me know.

[korttoma]

Hi @jpaulin thanks for this, I will test it immediately.

Would you mind sharing your complete sketch? The MySensors W5100 GW example has all this Soft SPI stuff, I might make a mistake clearing out all the unnecessary parts.

Btw, do you see any problem with me adding some local "sensors" to this type of GW? I would like to add 4 relays and 4 buttons to it also.

[korttoma]

It is alive :D

I managed to get a W5100 RFM69 Gateway working.
I wanted minimal change to the w5100.h so I just added the cli(); and sei(); macros.
(I would still like to see your sketch @jpaulin to compare)

There are some random failures in the RF communication but these might be because of the breadboard setup. I just have one temp sensor sending in some value now to test with.

@korttoma
Here's my sketch. It's an MQTT GW with LEDs.

little side note about the rfm69 driver : it will use spitransaction which should solve this, with some noint/int should be ok. (https://www.arduino.cc/en/Tutorial/SPITransaction)

It has been running for a few hours now without issues. Gona try adding the buttons and relays tomorrow.

[korttoma]

Adding the relays and buttons seems to work fine also. I will go with this setup now until there is a "Official" solution for the GatewayW5100RFM69.

@korttoma Excellent news. So now we are at least two with a stable RFM69-Ethernet-GW. :smiley:

[jpaulin]

@korttoma Sharing a pair of photos of my gw. Became pretty neat, I think. It's parked permanently beside the WiFi Router.

[korttoma]

I've seen pictures of your GW in another thread, it is very nice and professional @jpaulin

I stil have some parts missing from my GW build so I only have the breadboard setup right now.

@TimO
Hi.
Sorry for delay, so much projects.
As you tried to make a push, when you'll have some time, could you tell me if SOFTSPI is working please ? i'm a bit lazy to make a w5100 setup, as i'm not using it.

https://github.com/scalz/Mysensors/tree/rfm69_update

Set of defines is

//#define MY_DEBUG
//#define MY_DEBUG_VERBOSE_RFM69

//#define MY_RFM69_CSMA_ADD_DELAY_BASE 50  // default 50ms
//#define MY_RFM69_CSMA_ADD_DELAY_COUNT 10 // default max 10 counts

Note these are my defines for my ATSAM gw.

You can also send RSSI and powerlevel as internal msg by doing, like sendBattery function works.
Example:

/* ======================================================================
Function: sendRadioStats
Purpose : Sends radio rssi and powerlevel values
Input   : - force : Forces transmission of a value (even if it's the same as previous measurement)
               - ack : boolean. true if ack needed
Output  : - true if transmission occured
Comments:
========================================================================= */
bool sendRadioStats(bool force, bool ack)
{
   static int16_t lastRssi=0;

   int16_t rssiVal = transportGetRSSI();
   uint8_t txPower = transportGetTxPower();

   if (abs(lastRssi - rssiVal) >= 10 || force == true) {
      force = sendSignalStrength(rssiVal, ack);
      force |= sendTXPowerLevel(txPower, ack);
      lastRssi = rssiVal;
   }

   return force;
}

Hey @scalz !

My last test a few days ago was not successful with SoftSPI but I did not have the time to debug it. I'll give it another try!

[scalz]

@TimO
oki thx. Perhaps it was because of the w5100 CS define? i'll take a look.
