I checked the Bluejay project on GitHub. There is a hex file for M_H_30. Three variants, in fact.
Blhelisuite says something like this file can’t be flashed using a bootloader. The other two options are the Bluejay software and the configurator website, both of which doesn’t detect three ESCs
I don’t know what else to tell you. Perhaps those ESC’s are fake. Cheap enough to be…
I got a new lead. With Pixhawk passthrough, I wasn’t using the Cleanflight interface. With cleanflight inteface, it detected that there are 4 ESCs but three of them have unknown firmware on it. With the Arduino 4way interface, it detects all of them correctly and I also flashed the latest firmware.
I saw an RCGroups thread that said that this is because there’s no bootloader on the unknown ESCs… I guess I have to flash the bootloader now.
Can someone please tell me where to find the clock and data pads on this?
