With Weather4D enabled in the Mac's "Location Service" settings, the GPS position is well received from the GNS3000 : On my first try I had no problems, except that the data was only received at the speed of 38400 bps (while the device is factory set to transmit at 4800 bps) :Īs for the USB connection, MacENC圆4 recognizes the GNS3000 port by selecting the type = Other and flow rate set to 38400. When it works, it is super ! The GNS3000 is well recognized and the connection can be activated. Note that the latest version of OpenCPN 5.6.0 for Mac is not given as compatible with macOS 11/12 and does not detect the serial port. Weather4D Routing & Navigation does not read the serial port, because this function does not exist on iOS. I specify that I tested with my "old" BU-353S3 who is more than ten years old, not the most recent BU-353S4.īut beware, to date only the navigation application MacENC圆4 directly recognizes the serial port, by selecting the type = SIRF USB, and displays the position. With the CoolTerm utility, we can now display the NMEA sentences that are sent by the GPS. Once the BU-353 is connected to a USB port on the Mac M1 (using a USB-C converter), the driver creates a serial port usbserial-xxx. The same goes for the GNS3000 ( ¹) in Bluetooth that was experiencing a recognized instability of the interface for connecting multiple devices, instability that unfortunately does not yet seem to be fully fixed. In USB, despite the latest driver available Prolific V.2.1.0, we had to wait for the last update macOS 12.2 to make the GPS BU-353/S4 of GlobalSat operational. The arrival of Macs with Apple M1 processors and macOS systems 11 "Big Sur" and macOS 12 "Monterey" has caused disappointments among users of GPS connected via USB and/or Bluetooth for their navigation applications.
