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.
