BT121-A-V2 Frequently Asked Questions (FAQ)

  • The recommended antenna design for optimal Bluetooth performance is a 50-ohm, quarter-wavelength monopole antenna with a minimum of 10 mm clearance from the module's ground plane.

  • To configure the module for low power consumption, set the module to sleep mode using the HCI command 'hci_write_local_name' with the 'hci_sleep' parameter. Additionally, adjust the transmission power using the 'hci_write_tx_power_level' command.

  • The BT121-A-V2 module supports a maximum data transfer rate of 2 Mbps in Bluetooth 5.0 mode and 1 Mbps in Bluetooth 4.2 mode.

  • Yes, the BT121-A-V2 module can be used with an external MCU. The module provides a UART interface for communication with the MCU, and the MCU can control the module using AT commands or HCI commands.

  • To implement secure pairing and encryption, use the Secure Simple Pairing (SSP) protocol and enable encryption using the 'hci_write_encryption_mode' command. Additionally, use the 'hci_write_local_oob_data' command to set the Out-of-Band (OOB) data for secure pairing.
