BRIEF DESCRIPTION
SBT-810-RD is targeted for plug-and-play simple industrial
applications without need of an external host controller and programming. All
basic signaling control and data flow are done by on-board 16-bit CPU.
Therefore, it is very easy to apply this transceiver to wireless

and debug embedded Bluetooth software
|
No need
|
Need at
least three (3) months
|
|
Bluetooth
Communication stacks

|
|
Hardware
Interfaces
|
Standard
Interfaces: RS-232, RS-485 USB. One can select one of the three (3)
options and directly connect it to any
data collection equipment without any
level shift circuits
|
One can
not direct connect the UART or USB to
any data collection equipment. Level
shift circuit and other circuits are
required and proper drivers and
communication protocols (such as serial
comm) has to be developed, respectively
