Description:

A RF function is added to initial BLE module which expands the communication range from the original 15 meters to 100meters-500meters. It is compatible with Bluetooth BLE v4.0 and 4.1 standard, and featured with less communication latency and lower cost.

Specialized JINOU program firmware is embedded to the module, which enables users to set parameters, including baud rate, device’s name, etc., ensures fast connection and easy operation, and supports a variety of low power consumption profiles and data transmission to each other, and facilitates the connection with BLE Bluetooth supported cellphone. What’s more, we supply you with test APK for your development on mobile phone end after-sale .

Features:

1.Bluetooth specification: BLE 4.0(Bluetooth version 4.0 low power consumption), support both central and peripheral mode

2.Support point-to-point, and point-to-multipoint mode 

3.Allow firmware update online

4.Built-in antenna can reach 100 meters away, outside antenna can maximum reach 500meters(a pair of devices transmit to each other in spacious places)

5.Automatic energy saving, low power consumption mode is available 

6.Certified by FCC, CE, RoHS,etc.

7.Allow users to set baud rate（1200~115200bit/s）, device name, central or peripheral mode, parameter of energy-saving, etc.

8. RSSI output and Carrier Sense

9. Built-in Protocols

LL：Control the signal of RF

SMP：Manage the encryption key and identity key storage

L2CAP：Divide base data into groups and then exchange them to facilitate the high-level data packet format

ATT：Achieved PPP between client and server

GATT：There are 16 kinds of specific criteria about how to build connection

GAP：The profile is assured to find other Bluetooth products and build connection.

In addition, low energy version 4.0 Bluetooth module can be set to add following Bluetooth profile: SPP, HID, OPP, HDP, CTP, GOEP, HSAGP, BIP, BIR, PPP, BPP, UPD, LMP, ICP, MAP, CTP, DID, MAP, GOEP, L2CAP, RFCOMM, SDP, GAP, GATT, ATT
