When uusing RFM69HW i must also use Capacitor as for NRF24L01 ?

[korttoma]

@pepson

I do not think that the RFM69HW is as sensitive as the NRF24L01 but adding a Capacitor will not hurt.
It also depends on how clean your power source is. If the power is clean you do not need to filter it using Capacitor.

Hi guys!

I'd like to ask you about a problem. When I use RFM69 radios on my nodes, they are working fine, but when I try to use the NRFs everything is falling apart and that's driving me crazy. I can't find the solution to use NRFs (I've got 20 of them). I tried everything, read the forum a hundred times, but can't find the solution. Poer sources are perfect, every NRF has it's own 3.3v source and after a few hours or a few days perfect working, the nodes disappear (not all and not in the same time). I'm using Domoticz as controller on a RPI 2. I saw the node's L13 led's blinking is much lighter after the node disappears. When it's working okay, the led is blinking on full.

Thank you for the suggestions, and have a nice day

@ZsoltZombori what does the serial debug output of the nodes say?

@ZsoltZombori

I had a problem of the LED on pin 13 glowing dim after some time of system running fine when I had 2 sensors connected to the Arduino and sensors had their own separate 5V power supply. So, I had a 5V power supply separate from the Arduino's 5V and that was supplying current to those sensors.

I had the sensor's data pins connected to Arduino but I didn't have GND of power supply and Arduino connected. I solved the problem by connecting the GND of power supply to the GND of the Arduino.

See if that is the case with you.

Hope this helps.

@mfalkvidd I put the node on serial for the night and everything works fine now. No errors occured, I'm still waiting.
@palande-vaibhav The GNDs are always connected in my circuits to prevent GND problems. Thanks for the tip.

[palande.vaibhav]

@ZsoltZombori
Exactly that was a problem with my system too. When I had it connected to the computer using the serial cable everything would just run fine but as soon as I removed the serial cable from computer and let it run on its own with the power supply connected with a DC jack, everything would just fall apart the LED's would go dim and that's when I discovered the problem of the ground but you already have all the grounds connected so I'm out of clues here.
I would suggest you to check the power supply connections again with a multimeter to make sure that everything is connected properly.

@palande.vaibhav I double checked everything and the PCB is perfect. Still waiting for a failure, but it's working now. I'm wondering what was the problem for weeks with the NRFs. The RFMs are working like a charm. Anyway, thank you for the ideas :)

How i must change sketch Gateway and node to use radio RFM69HW ? In sketch i see only for simple RFM69 not RFM69HW.

[scalz]

for using RFM69HW, you just need to use the common rfm69 defines and add this

#define MY_IS_RFM69HW

[rmtucker]

@scalz
Do you add the rfm69hw def to the gateway sketch or to the myconfig.h?

[korttoma]

@rmtucker

You add the #define to your sketch

Hi @scalz ,
Will a RFM69HW work without the "#define MY_IS_RFM69HW" ?

What exactly does this #define do for the HW version?

Have only used RFM69W so far but have ordered some HW now also.

[scalz]

to your GW sketch.
Also, for using RFM69H you need this define,else the radio can't work properly. This allow us to set the right Radio power level registers in lib.
@korttoma just curious :) Have you tried my rfm69 repo?

[korttoma]

@scalz
So does a H version radio work if you do not set the high power registers?

@scalz said:

@korttoma just curious Have you tried my rfm69 repo?

Sorry, I have not yet had the opportunity to test your repo. There is so much non MySensors activities now when Christmas is approaching.

[pepson]

With radio RFM69HW for gateway sketch should looks as:

/**

• The MySensors Arduino library handles the wireless radio link and protocol
• between your home built sensors/actuators and HA controller of choice.
• The sensors forms a self healing radio network with optional repeaters. Each
• repeater and gateway builds a routing tables in EEPROM which keeps track of the
• network topology allowing messages to be routed to nodes.

• DESCRIPTION
• The ArduinoGateway prints data received from sensors on the serial link.
• The gateway accepts input on seral which will be sent out on radio network.
• The GW code is designed for Arduino Nano 328p / 16MHz
• Wire connections (OPTIONAL):
• • Inclusion button should be connected between digital pin 3 and GND
• • RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
• LEDs (OPTIONAL):
• • To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
• • RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
• • TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
• • ERR (red) - fast blink on error during transmission error or recieve crc error

@pepson if you're using an Arduino Mini pro or equivalent, and follow the recommanded wiring for the radio (CS and INT), looks ok to me.

@korttoma oki. no it won't work if the define is not set for HW version, and vice versa. Because the W and HW use different registers for setting power levels

[pepson]

Now i test it on Arduino nano byt finally i want use it on Arduino Mini Pro. Wirering i use as show on this page.

[scalz]

@pepson oki. But you've not explained what's your problem, without logs etc..

[pepson]

Now any problem. I only need info how write sketch to use radio RFM69HW.

[rmtucker]

@scalz
Is there an instruction to alter the power level on the RFM69?
From inside a mysensors sketch like the NRF24_PA_level?
