Pin definition (from right to left)
| Pin No. | Description | Pin Type | Functions |
|---|---|---|---|
| 1 | BLE_RX | Digital I/O | UART RX |
| 2 | BLE_TX | Digital I/O | UART TX |
| 3 | WAKE_UP | Output | Digital I/O |
| 4 | STATUS | Input | Digital I/O |
| 5 | GND | Digital I/O | GND |
| 6 | V+ | Digital I/O | VDD |
| 7 | BLE_EN | Digital I/O | VDD Enable |
How to use:
– Before sending any UART Command, “WAKE_UP 1 → 0” must be done by an external
MCU.
– If the RF module is connected to Smart Devices (Android/ iOS), the pin
STATUS will be logic “1” to inform external MCU.
– Beacon
- Send Command ‘R’ to send live measured data from external through Beacon.
- This is the default mode, and the RF module sends data only. Cannot receive any data.
– BLE
- Send Command ‘M’ to switch mode from Beacon to BLE.
- After the mode switch successfully, the external MCU can receive data from Smartphone.
– Receiver
- Send Command ‘E’/’G’/’I’ to switch mode from Beacon to Receiver.
- Only specific Beacon data can be received, and the external MCU receives the data from UART
Protocol:
– UART Baud Rate: 115200, 8, N, 1

Federal Communication Commission Interference Statement
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 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: To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. (Example – use only shielded interface cables when connecting to computer or peripheral devices).
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID: VEABT006″ ”
End Product Manual Information
The user manual for end users must include the following information in a
prominent location “IMPORTANT NOTE: To comply with FCC RF exposure compliance
requirements, the antenna used for this transmitter must be installed to
provide a separation distance of at least 0.5cm from all persons and must not
be co-located or operating in conjunction with any other antenna or
transmitter.” This device complies with part 15 of the FCC rules. Operation is
subject to the following two conditions (1) This device may not cause harmful
interference and (2) This device must accept any interference received,
including interference that may cause undesired operation.
IMPORTANT NOTE: In the event that these conditions can not be met (for
example certain laptop configurations or colocation with another transmitter),
then the FCC authorization is no longer considered valid and the FCC ID can
not be used on the final product. In these circumstances, the OEM integrator
will be responsible for re-evaluating the end product (including the
transmitter) and obtaining a separate FCC authorization. This device is
intended only for OEM integrators under the following conditions: The antenna
must be installed such that 0.5 cm is maintained between the antenna and
users. As long as the condition above is met, further transmitter tests will
not be required. However, the OEM integrator is still responsible for testing
their end-product for any additional compliance requirements required with
this module installed (for example, digital device emissions, PC peripheral
requirements, etc.).
