RFM69 ATC not working?

TSD

#define GATEWAY_DEBUG(text)

or

#define MY_DEBUG

doesn't show any additional messages in the log, besides the node messages.

In the mean time I installed Domoticz to try it your way, but don't see the USB port that I tried to make by installing the serial gateway (ttyUSB020, which is not in /dev yet, so should be free).

This command should take care of that, right?

./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020

Sorry to be such a pain, but I would really like to get this sorted out.

@tsd sorry for being unclear. This is how to use GATEWAY_DEBUG:

GATEWAY_DEBUG("This message will be sent to the debug log")

But I am not sure it is available in sketches and I don't have access to a computer at the moment.

The configure command looks good. After running configure, did you continue with make, etc?

TSD

@mfalkvidd
Do you mean

#define MY_DEBUG_VERBOSE_GATEWAY

That uses the GATEWAY_DEBUG("text") macro that you are referring to. I tried that, but it doesn't give any additional output in the log.

Yes, this is the complete code I run:

sudo ./configure --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyUSB020
sudo make install
sudo systemctl start mysgw.service

But ttyUSB020 doesn't appear in /dev afterwards, nor does Domoticz list it.

mfalkvidd

@tsd I think you'll need to run make before make install.

configure prepares the settings for make
make compiles the code into an executable file called mysgw, including changes to the cpp file and the settings from the configure command
make install copies the mysgw executable to /etc/init.d/

TSD

If I run "make install" while the code has not compiled yet, it will compile before installing. If you first run "make" seperately, "make install" will only install.

I'm almost there. I configured an Ethernet gateway (couldn't get serial gateway to work) and can now see the temperature, receive RSSI and sending RSSI from the node in Domoticz.

The gateway receive function shows up as "S_ARDUINO_REPEATER_NODE", but there's no data yet.

What data should I pass on to your receive function? My gateway code is now as follows:

#define MY_DEBUG_VERBOSE_GATEWAY
#include <MySensors.h>


MyMessage msgTemp(1,V_TEMP);
MyMessage msgRSSI(2,V_LEVEL);

#define ARDUINO 100
// This space is intended to be used to include arduino libraries

#undef ARDUINO

void setup()
{
        // Setup locally attached sensors
}

void presentation()
{
        // Present locally attached sensors here
present(2,S_SOUND);
}

void loop()
{
        // Send locally attached sensors data here
receive(msgTemp);
}

void receive(const MyMessage &message)
{
  int16_t rssiReceive = RFM69_getReceivingRSSI();
  if (message.sender == 1 ) {
    send(msgRSSI.set(rssiReceive,0));
  }
}

mfalkvidd

@tsd MySensors will automatically call receive() when the node receives a message. It should not be called manually.

This is how I monitor RSSI and power % from the node: sending RSSI should be close to the RSSI target value set in the config file. I left atc enabled and if I move the node away from the gateway I see the power % going up while RSSI value stays more or less the same.

#ifdef MY_RADIO_RFM69
	rssi = RFM69_getSendingRSSI();             // read RSSI in RFM69. Measure reception signal from gw
	send(msgRSSI1.set(rssi));                  // send RSSI level
	wait(500);                                 // wait to get idle

	rssi = RFM69_getReceivingRSSI();           // read RSSI in RFM69. Wait and measure background noise
	send(msgRSSI2.set(rssi));                  // send RSSI level
	wait(200);                                 // wait for next send

	PwrPcnt = RFM69_getTxPowerPercent();      // read TX Power in RFM69
	send(msgPWR.set(PwrPcnt));				  // send TX Power
#endif

TSD

@mfalkvidd
My code now looks pretty much the same as yours, except for the OTA stuff. But I don't see gateway messages in Domoticz. The node shows up with all its measurements.

#define MY_DEBUG_VERBOSE_GATEWAY
#include <MySensors.h>

MyMessage msgRSSI(1,V_LEVEL);

#define ARDUINO 100
// This space is intended to be used to include arduino libraries

#undef ARDUINO

void setup()
{
        // Setup locally attached sensors
}

void presentation()
{
        // Present locally attached sensors here
present(1,S_SOUND);

}

void loop()
{
        // Send locally attached sensors data here
}

void receive(const MyMessage &message)
{
  int16_t rssiReceive = RFM69_getReceivingRSSI();
  if (message.sender == 1 ) {
    send(msgRSSI.set(rssiReceive,0));
  }
}

Is the gateway supposed to show up as a measurement? Any idea why that doesn't happen?

TSD

@gohan
I added your code to my node. It gives exactly the same results as my own code. What kind of node are you using? Are you using the HW or W version of the RFM69?

gohan

it works the same, of course if you have a HW version you will see TX power % lower compared to a W module. I am not using those functions on the gateway because they are actually more node related

TSD

@gohan @mfalkvidd
I think it is related to the Raspberry Pi implementation of MySensors. If I use an Arduino/RFM69 gateway, the RSSI is as expected. At close range, the power drops to the minimum possible level and the RSSI is strong. I noticed that the interrupt pin is toggled during communication, see picture below (orange is node current, blue is gateway interrupt).
0_1540320711757_arduino-gateway_node-current_gw-interrupt.bmp

If I use the Raspberry gateway (with origin/development-3.0.0 MySensors), I get the following result (orange is node current, yellow is gateway interrupt). The same result is obtained with MySensors 2.3.0 (origin/master). I couldn't get the origin/development version to compile. It gives an error about MY_DEBUGDEVICE.
0_1540320810723_raspberry-gateway_node-current_gw-interrupt.bmp
Apart from the much higher node current (and worse RSSI), the interrupt pin is always high and not toggled.

Are you guys using a Raspberry gateway, or an Arduino gateway?

I haven't had time to dig into to the MySensors code further, but does any of you know if this could be the problem?

mfalkvidd

@tsd nice work. I'm using an esp8266 gateway but I don't use atc.

gohan

I am using raspberry with both nrf24 and rfm69 gateway on it, but I am still version 2.2.0

diogoc

I have problems too with the linux gateway

I just tried with the node on MySensors 2.2.0, but I get the same result. I cannot get the gateway to compile with 2.2.0, I get the following errors:

Do you have the gateway running with 2.2.0? And ATC works for the RFM69?

TSD

@mfalkvidd
And if you turn on ATC? Does that work? Are you on 2.3.0?

mfalkvidd

@tsd I don't know which version I am using. I'm currently travelling so I can't check easily.

TSD

@scalz
I found your name in the Raspberry Pi MySensor driver files. Would you happen to know why the RSSI measurement for a RPi gateway doesn't work? I'm having trouble getting ATC to work with my RPi gateway. It works well with an Arduino gateway.

gohan

I still don't understand the need to measure RSSI on gateway...

TSD

@gohan
I couldn't get the RSSI measurement on the gateway to work, so I'm not doing that.

I want to get ATC to work. As ATC uses RSSI to optimize power, a correct RSSI measurement (on the node) is needed. ATC (and so the RSSI measurement) works well on an Arduino gateway, but not on a RPi.

As I don't have a software background and am still newish to MySensors, I'm hoping someone on the forum knows what to do. In the meantime, I'll keep digging myself :)
