4712 on github has been working to troubleshoot this issue.
The log file from BLH32Suite shows that Arducopter does not respond properly to the MSP_API_Version call, but respond with a text string instead. Does anyone understand why?
This has been figured out. I can now communicate between BLH Suite and the pixhawk.
After reading, reading, reading, and watching lots of utube clips my understanding was that parameter, “Servo_blh_port” defined the port for the ESC telemetry, in other words, this port would receive the broadcast telemetry from the esc’s. NOT TRUE.
SERVO_BLH_PORT defines the com port for all pass thru communications between the BLH Suite software and the flight controller. BLH Suite softare will only connect over usb, so,
SERVO_BLH_PORT MUST ALWAYS EQUAL ZERO FOR USB COMMUNICATION
