1 Introduction
The BTM-5 Module has two operation modes, one is normal auto link mode, and the other is
AT command mode. User can switch between two modes via pull the mode select pin PIO11 low
and high respectively.
The normal auto link mode is the basic operation mode, each Master/Slave BTM-5 pair auto
link with the default device address after power up. After link is established, user can transmit and
receive data via the UART interface with each other. The transmission is almost transparent to user,
it acts as tow UART connect with each other wirelessly.
The AT command mode is the advanced operation mode. User can use supported AT
command to change the default configurations, such as device name, link password, UART baud
rate and etc.
