3.6.4. UART Interface
FG50V supports an HCI UART as defined in Bluetooth Core Specification Version 4.0. In addition, the UART
interface also supports software (in-band) sleep control of Bluetooth with Quectel RG50xQ series. You can also
choose other 5G modules upon validation tests. If you have any questions, please contact Quectel Technical
Support.
The following table shows the pin definition of UART interface.
