LM746 / LM747: How can I configure the module?

Modified on Wed, 13 Sep 2017 at 05:09 PM

The LM746 and LM747 are both programmable using AT commands via the UART interface. Using AT commands, the host can access Bluetooth functionalities without involving the Bluetooth protocol stack. The AT command reference can be found here.

The default factory firmware settings are:

Baud Rate: 19200
Parity: 0 (None)
Stop Bits: 1
Flow Control: 0 (None)
Deep Sleep Mode: 0 (Disabled)
Local Echo: Enabled
Pin Code: 0000
HFP Volume Level: 15
A2DP Volume Level: 8

The LM558 multimedia development kit is designed to evaluate the LM746 / LM747. The product page can be found here.
