💬 Connecting the Radio

[scalz]

@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.

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

[scalz]

@rmtucker no not yet (not sure, i need to check). But yes, in the next release ;)

Try the MockMySensors.ino sketch and enable a few sensors.

[pepson]

Good will be add manual how in sketch change level for RFM69HW when new version released. I know that should be released on chrismass

@pepson if you have been kind this year, perhaps :laughing:

I'm having trouble with the distance between my 2 RFM69 radios. If I use this tutorial and change the frequency to 433 mhz I get distances of up to 10 meters - https://learn.adafruit.com/adafruit-rfm69hcw-and-rfm96-rfm95-rfm98-lora-packet-padio-breakouts/rfm69-test

However if I use the Mysensor libraries for the SerialGateway and the door sensor I don't even get 1 meter.
I tried to declare these variables as well but no success.

#define RFM69_FREQUENCY RF69_433MHZ
#define IS_RFM69HW

Any suggestions I might try out?

Thanks,
Martin

If i buy from aliexpress RFM69HW and when buy i select to seller info that i want 868MHz and on PCB RFM69HW has select/write 868MHz in sketch i must use item:
#define RFM69_FREQUENCY RF69_868MHZ ?

[martins]

@martins

Solved. This is the extra variables for the RFM69H / HW versions and to set the frequency.

#define MY_RFM69_FREQUENCY RF69_433MHZ
#define MY_IS_RFM69HW

Range is now acceptible.

Regards,
Martin

@pepson

From library API:

MY_RFM69_FREQUENCY RF69_868MHZ For other frequency, add this define to your sketch and set it to your preferred value in RF69_433MHZ, RF69_868MHZ or RF69_915MHZ

So it seems that 868MHZ is the default value.

Ok thanks

I m getting symbols when I send Hello World message from Arduino Uno to an Arduino Pro Mini (5V).
Yes I have put an input of 3.3V to the pro mini.
Baud rate used is 9600.
Any clue why this is happening? I can provide the code.

[mfalkvidd]

@LaMB95 are you using a Pro Mini 5V 16MHz or Pro Mini 3.3V 8MHz?

If the wrong variant is selected in the Arduino IDE, all timings will be off, including the timings for serial communication.

@mfalkvidd

I have an arduino pro mini 5V. But I have attached a breakout CP2102 usb connection to it. On the board there is a 3.3V point which I have plugged in as Vcc to the NRF24L01+ module.

To upload the code I have selected the 5V 16Mhz as processor.

[mfalkvidd]

@LaMB95 Interesting. I have never seen a 5V Pro Mini with 3.3V output. Where did you get it?

Try different serial speeds in the serial monitor and see if you get something readable.
