I am using the following 433 MHz antenna set (check image) for my quadcopter, for the last 6 months now.
However, it has now stopped working. The green light keeps on blinking
Maybe I have upgraded the ground module from Sik radio by mistake. But I am not able to upgrade the air module as it does not support a micro usb connection like a Sik Telemetry radios.
Can anyone please help me out?
