We are using openimu300za sensor without EVK. We are trying to connect the sensor to the system using TTL to USB converter. We have used pins 3, 4, 12 & 13 for User UART Tx, User UART Rx, Vcc & Gnd respectively. We are getting the junk data using cool term(got data in tera term and putty as well), but not sure of the data format we are receiving. And then we tried to connect to the Aceinna navigation studio, but couldn't establish a connection to it. When the executable file, IMU server was opened for connecting to the studio, it detected the COM port but was throwing an error "Cannot configure port, something went wrong, original message:OSError(22,'the parameter is incorrect), none,87)" and was closing by itself. Please suggest on how we can get the correct output from the sensor by using any other pins apart from what we have used now.
