SUPPORTED SERVICES

The RN4870 supports four built-in GATT services:

• Device Information public service

• Airpatch private service, which handles Over The

Air (OTA) updates

• BeaconThings, which handles beacon services

control

• UART Transparent private service, which handles

data streaming function

In addition to the above predefined private services, the

RN4870 provides the ability to create private services.

If the services are supported on both end points of a

Bluetooth Low Energy connection, such as Central and

Peripheral devices, data can be exchanged. For

example, two RN4870 modules can define a custom

(private) service with its own unique characteristics.

Data can be exchanged easily via Command API.

Private services are not registered with the Bluetooth

SIG, and therefore not interoperable with other

Bluetooth Low Energy devices, unless the device

implements the private service. An example of a built-

in private service is the Transparent UART. For an

example on how to create a custom service using the

RN4870, refer to “RN4870/71 Bluetooth® Low Energy

Module User's Guide” (DS50002466A).

RN4870 allows custom defined services up to five

public and four private services. Each custom defined

service

allows

eight

custom

defined

characteristics. All service definitions are saved in

on-board Non-Volatile Memory (NVM) where the user

must setup the module only once.
