As an FYI, I am trying to use the receiver RF module with the DigiX (without the transmitter) and am simply using the "receiver" sketch to try to "listen" to RF data from RF remotes, garage door openers, and 433MHz Ambient Weather stations that send data every 30 sec.
Though I am an intermediate user, I feel that no detail is trivial enough as I am not seeing any response in my serial monitor when testing my receiver module.
Message with a good checksum received, dump it.ĭeleting the if (vw_get_message(buf, &buflen)) statement gives me a lot of garbage on the serial monitor, so I can receive at least something.I'm trying to replicate your success with a 315MHz / 433MHz transmitter / receiver module that I picked up here: I have not had any success in using the module and would appreciate if you could share with me your setup and how you are using/testing your module to verify that it is working as expected. If (vw_get_message(buf, &buflen)) // Non-blockingĭigitalWrite(13, HIGH) // Flash a light to show received good message Vw_rx_start() // Start the receiver PLL running Now its hard to say if this is a reciever or transmitter problem now. It should blink and print the "hello" message via serial but its not doing that. Though I still don't know if the transmitter is acutally sending something, I have my ADK hooked up to the reciever and its running the reciever example from the VirtualWire libary. Ok so the LED problem was super simple, I just didn't specified PIN13 as output. Vw_wait_tx() // Wait until the whole message is goneĪnd here two pictures of the hook up to the arduino: vw_set_ptt_inverted(true) // Required for DR3100ĭigitalWrite(13, HIGH) // Flash a light to show transmitting
This is the code of the transmitter example from the VirtualWire libary #include The model name of the transmitter is QAM-TX2-433-ND but I guess this is more of a code than a hardware problem? Though here is the datasheet of the transmitter if thats of any help: I have honestly no idea why this isn't working. When I reset the Arduino UNO I can see the TX LED blink once for a very short amount of time (which is the serial.print I guess) and after that the onboard LED is just constantly glowing. Now when I understand the sketch correctly this should send "hello" in an infinite loop and blink the onboard LED everytime. I'm using Arduino IDE 1.0.1 with VirtualWire 1.9 (the one coming with 1.0.1 didn't compile). I'm trying to get an RF transmitter/receiver pair from digikey to work with my Arduino Uno/Mega ADK.īut it seems neither the transmitter nor the receiver example are working with any of my Arduinos.Īt the moment I focused on the transmitter for now (hooked up the UNO) as its more obvious to tell when its working or not.
