2.4. Antenna Layout
HF-BL200A supports internal antenna.. Customers need to obey following antenna design rules
and module location suggestions:
For user PCB, place module on the edge area of the PCB as possible, or suspend the
antenna area.
Module antenna（5mmx12mm）correspondent area can’t put components or paste GND,
the surrounding components or GND should be as far as possible from antenna place.
Antenna must be away from high components at least 10mm.
Antenna can’t be shielded by any metal enclosure.
High Flying suggests to locate HF-BL200A as Figure 5 to reduce the influence to antenna and
wireless signal as much as possible, or contact High Flying technique people for support

3.UART TRANSPARENT TRANSMIT MODE
3.1. Transparent Transmit Mode
Transparent Transmit means the two way communication between device and mobile terminal via
the connecting with serial interface and device MCU. Device can set HF-BL200A baud rate and
connect interval via AT command through serial interface (refer to “Serial AT command
Description”for details). Target different baud rate and BLE connect interval or different packet
sending interval, module would have different data handling capacity. The default baud rate of HF-
BL200A is 115200bps, it is recommended to set baud rate at 115200bps when transmitting big
data or in highly real-time application. Baud rate support save after power off.
Figure 6. Basic HF-BL200A wireless network structure
Module BLE connect interval is 20ms, and it is able to send almost 200 byte data one time via
serial interface. Theoretically, module is able to send data up to 4KB/S. Below is the detail description
about transparent transmit.
Module can receive almost 200 byte data from serial interface one time. Module will automatically
send sub-packet according to data size, each packet limit is 20 bytes. The data packet sending from
mobile device to module must be separated to sub-packet(1-20 byte each). After receiving the sub-
packets, module will send to MCU in proper order.
Serial hardware protocol: 115200 bps, 8,non-parity, 1 stop bit
After receiving data from MCU serial port, module will judge if it is AT command. If it is, module
will execute the command. If not, module will transmit the data to APP under BLE connection and
notify mode enabled status.
After module receives APP data, it will output the data to MCU via serial interface.

Shanghai High Flying Electronics Technology Co., Ltd www.hi-flying.com - 17

If module system status changed, module will send status notification character to MCU, such as
disconnect, connect, broadcast.
Bluetooth protocol require that the minimum connect interval is 7.5ms. Default connect interval is
20ms (comply with IOS regulation), if it is needed to save power and apply low speed transmit mode.
User can adjust connect interval through AT command ( the maximum connect interval is 2000ms,
comply with IOS regulation)
The calculation of transmit speed : the data packet of each connection interval from APP to
module is 1 packet, max 4 packet can be transmitted from module to APP in each interval (the packet
is related to module CPU capacity) . There is maximum 20 bytes in each packet, if connect interval is
T (unit :ms), then max transmit speed V (unit is byte/s) is :
Vmodule = 20*4*1000/T (V only related T )
Vapp=20*1000/T (V only related T )
Vapp：if module connect interval is 20ms, then each interval can transmit max 20 bytes, so
theoretically the max speed is 20x50 =1k byte/s. Test shows the transmit from APP to module is
stable and reliable.
Vmodule：if module connect interval is 20ms, then each interval can transmit maximum 80 bytes,
so theoretically the maximum speed is 80x 50=4k byte/s. Test shows that if transmit speed is under
2kbyte/s, there is few chances of leaking packet. For safety consideration, it is recommended to do
verification and re-transmit at up level whatever it is low speed or high speed application. In Android
application, it is recommended to lower connect interval to increase speed.
Below is the example of 20ms connect interval communication mode, user can self-configure. The
lower the Speed, the lower the packet lost ratio.
Table 8 Module connect interval 20ms communication mode example

Shanghai High Flying Electronics Technology Co., Ltd www.hi-flying.com - 18
-
Remark：user can set particular communication mode according to actual application, packet
length can be set between 80byte < L < 200byte ，the relationship as below as per BLE protocol:
If L<80 ，TS >= T ；
If 80<L<160 ，TS >= T*2 ；
If 160<L<200 ，TS >= T*3 ；
All transmit mode is safe as long as it meets above conditions, TS=T is recommended,
TS=T*2，TS=T*3 is ok but the packet lost ratio is high, must add verification and re-transmit
mechanism. In another words, if apply 80byte < L < 200byte ,serial data can transmit to module in one
time, but need to reserve time for sending data from module to Bluetooth, or there will occur rear-end.
E.g. Set connect interval T=20ms, if data length is L=200, TS must over T*3 = 60ms , TS=70ms is a
reasonable choice.
Serial data length can be any value under 200 byte. In order to achieve the best efficiency and
avoid full load operation , it is recommended to use 20,40,60 byte serial data packet, set packet
interval over 20ms.
Remark：in IOS, the function is used to call Characteristic is:
BCharacteristicWriteWithRespons
e parameter, “write with response”mode would lower transmit efficiency to ensure the accuracy
of each packet. Using “CBCharacteristicWriteWithoutResponse” ; “write without response”mode
would promote transmit efficiency , but the accuracy of packet need to be verified by APP up level.
