I am using my Raspberry Pi as a radio transmitter. I'm using the Pi FM RDS program. It works fine for a few seconds, but then it just suddenly stops broadcasting the sound. The program is still running, but there is no more sound. It works fine again once I start the program again, but then it stops working again after a few seconds. I tried all radio frequencies in standard FM range, I tried unplugging the wires from GPIO pin 4, I tried adjusting the ppm and audio settings, I even tried a different program, still no success. Why is this happening?
I am using Raspberry Pi 2 (Yes, the program does work with RPi 2). I am running Raspbian Wheezy with a Waveshare Spotpear 3.5" Touchscreen TFT LCD and I am 75% sure GPIO pin 4 is not being used because I have tried it using RPi.GPIO in Python.
