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-BL100-CU 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-BL100-CU is 115200bps, it is recommended to set baud rate at

Basic HF-BL100-CU wireless network structure
Module BLE connect interval is 20ms, and able to send utmost 200 byte data one time via
serial interface. Theoretically module able to send data up to 4KB/S. Below is the detail
description about transparent transmit.
Module can receive utmost 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 separated to sub-packet(1-20 byte each).
After receive the sub-packets, module will send to MCU in proper order.
Serial hardware protocol:：115200 bps , 8, non-parity，1 stop bit 。

HF-BL100-CU Low Energy Bluetooh（BLE 4.0）Module User Manual
After receive data from MCU serial, 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 receive APP data, output the data to MCU via serial interface.
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 need 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 connect interval from APP to
module is 1 packet, max 4 packet can be transmit from module to APP in each interval (the
packet qty is related to module CPU capacity) . There is max 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
Vapp=20*1000/T
(V only related 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 max 80 bytes,
so theoretically the max speed is 80x 50=4k byte/s. Test shows that if transmit speed 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
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= T*2 ；
If 160= T*3 ；
All transmit mode is safe as long as meet 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 used to call Characteristic is:
BCharacteristicWriteWithRespons
e parameter, “write with response” mode would lower transmit efficiency to ensure the
accuracy of each packet, use “ CBCharacteristicWriteWithoutResponse” ; “write without
response” mode would promote transmit efficiency , but the accuracy of packet need to be
verified by APP up level.
