In the past my telemetry modules were able to connect (sold green light on both ends) and communicate. However for some reason after a quad redesign my quad module has a solid green light implying it has connected whereas my ground station module has a flashing green light. They are not able to communicate with each other.
I have not changed any firmware on either of the modules. I have, however, changed to a new Pixhawk. I did not think this would make any difference to the connection process however. There is a dim flashing red light on the transmitter, and I have checked both telemetry ports on the Pixhawk with no luck.
Unless you shorted something it’s unlikely it’s faulty. I must have a dozen of these radios from actual 3DR units to the cheapest eBay versions and they all work and have never failed. I don’t really understand the sporadic issues some are having. The only way I can reproduce them is to do something wrong… Certainly it’s not pervasive because they only pop up occasionally.
Sporadic issues seem to be pretty common for me at the moment! Been having very random Pixhawk, GPS, telemetry and power module issues with no obvious causes. Not sure how common that is for this hobby! I’m sure its most likely a fault of my own, but I’ve certainly not had an easy time trying to debug it all!
