I’m building a 450 drone using the BLHeli 20a ESCs sold on unmanned tech, however I can’t get them to be read by BLHeli suite using Cleanflight on my Naze32, an Arduino Uno or the BLHeli programmer also sold on the unmanned shop: the program just throws up the error “can’t connect to ESC, check power and connections”. Everything should work; the ESCs are powered by the battery, Cleanflight isn’t open so nothing’s interfering with the COM port and the ESCs are functioning normally, powering the motors through both Cleanflight and the transmitter. Although, 1 of the ESCs doesn’t seem to be functioning at all (the motor works fine) but I can’t see how that affects the other ones; I guess I’ll have to buy another one.
What’s going on? Any help appreciated.
