7 years ago Hi, sorry for my long delay, I had problem with my mail account.
I use arduino mega RFM69 and the Ethernet Shield as a MQTT gateway (MySensor version 1.5). I have not tested the transmission of text data from mega to other nodes, but I can control other nodes using the library and message types from the MySensor libraries. Communication works in both ways. I'm not sure if the MySensor library use the text types of command – I expect not. Can you send other types of messages (e.g. V_LIGHT) ?
One more thing: I understand that level-shifter module means double resistors (1 kOhm + 2.2 kOhm) to reduce power from 5 to 3 volts ? If yes you have to remember that this module should not be used with MISO line (from pin 16 at mega) and with DIO0 line (from pin 2 at mega) – I send you my diagram how to connect mega with RFM69 and ethernet shield.
I hope it could help. Grzegorz Miąsko

Hello,
I have implemented your lib to use RFM69 with Arduino MEGA. I will use your lib on this device because I will use this with Ethernet shield. All incoming Data will be OK, but when is send an Text, that will don’t be receive on the partner. When I change the lib to the standard lib of Felix and change the wiring to the hardware pins 50 – 53, all is fine.
My wiring is:
RFM69 <-> Arduino MEGA GND GND 3,3 3,3V DIO0 Pin2 SCK Pin 14 MOSI Pin 15 MISO Pin 16 NSS Pin 17
The Pin 2, 14, 15, 16, 17 are all connected with an level-shifter module.
Lib from Felix with this code: send works fine, receive works fine Lib from you with this code: send won`t work, receive works fine
So what`s wrong?
Here is the code:___
define NODEID 47
define NETWORKID 100 //the same on all nodes that talk to each other (range up to 255)
define GATEWAYID 1
define FREQUENCY RF69_868MHZ
define ENCRYPTKEY "unyu2x5b2rwx2nj4"
define IS_RFM69HW
