WT52832-S2
WT52832
USER MANUAL
Description:
WT52832 is a high performance ,low power radio transmit and
receive system module use Nordic BLE nRF52832 as the controller
chips. It has the smallest volume package in the industry, the size is
19.6*12.9*2.0mm, suitable for most applications which pay more
attention to the size. The module support low energy Bluetooth 5.0
protocol stack S132 drive.
Customer's MCU is connected to the module by UART port, it
will automatically send a broadcast code after the module starts. As
the master, APP device can scan and search the broadcast from
module in order to establish the connection. After success, it can
conduct two-way communication link with mobile device APP by
serial port. Through UART interface, the user can exchange data or
control the communication parameters of module. The meaning of
data is defined by the upper application user. The mobile device can operate to the module through APP,
the data will receive by the module and pushed through UART MCU. After the module received a data
packet from the client MCU serial port, it will be automatically forwarded to the mobile device.

FCC Warning Statement
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment. This
equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one
or more of the following measures:
‐‐ Reorient or relocate the receiving antenna.
‐‐ Increase the separation between the equipment and receiver.
‐‐ Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
‐‐ Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate this equipment.
