Compatible

Firmware completely meet Apple’s iBeacon’s technical standard and can be applied to systems. 

 

Iso7.0 or above 

 

Android4.3 or above

 

Waterproof design

Our iBeacon using waterproof design  , so that you can put them indoor and outdoor , it can broadcast where you put the iBeacon in tourist attractions for navigation or something else .

 

The appearance of beautiful design

Battery lifr  1-2.5  years    ,depends  on the  tx power   and  broadcast   interval 

 

Signal stability 

The long -distance far from the iBeacon ,  Data transmission can get stable   signal , Data transmission can get so far . We have already test the iBeacon device using APP tool , It works stable when in complex environment .

 

Configuration tool

The configuration tool which you can download LightBlue ,a  mobile app design for developer check and configure yunjia iBeacon 

 

Please see below what we set iBeacon : configurable pamameters

 

UUID mNEW ENHANCEMENTS include variants with 32kB RAM for improved application performance, and 128kB flash wafer level chip scale package (WLCSP) options for smaller wearable designs.

The nRF51822 is a powerful, highly flexible multiprotocol SoC ideally suited for Bluetooth Smart (previously called Bluetooth low energy) and 2.4GHz ultra low-power wireless applications. The nRF51822 is built around a 32-bit ARM Cortex M0 CPU with 256kB/128kB flash + 32kB/16kB RAM. The embedded 2.4GHz transceiver supports both Bluetooth Smart and the Nordic Gazell 2.4 GHz protocol stack which is on air compatible with the nRF24L series products from Nordic Semiconductor.

nRF51822 incorporates a rich selection of analog and digital peripherals that can interact without CPU intervention through the Programmable Peripheral Interconnect (PPI) system. A flexible 31-pin GPIO mapping scheme allows I/O like serial interfaces, PWM and quadrature demodulator to be mapped to any device pin as dictated by PCB requirements. This enables complete design flexibility associated with pin-out location and function.

nRF51822 supports Bluetooth Smart protocol stacks as well as 2.4GHz protocol stacks, including Gazell, both available as downloads. nRF51822 requires a single power supply and gives the user the option of using on chip linear regulators giving a supply range of 1.8-3.6V, a direct 1.8V mode and a on chip DC-DC buck converter giving a supply range of 2.1-3.6V. The use of the DC-DC converter can be dynamically controlled during run time and enables nRF51822 to operate at radio peak currents below 10 mA @ 3V supply (TX @ 0 dBm & RX).

nRF51 SDK provides extensive software support for both Bluetooth Smart and 2.4GHz proprietary applications.

nRF51822 is available in 6x6mm 48-pin QFN packages and 3 ultra compact wafer-level chip-scale packages (WLCSP).

nRF51822 is available in either 256kB or 128kB Flash + 32kB or 16kB RAM variants.

Nordic Semiconductor protocol stacks are known as SoftDevices. SoftDevices are pre-compiled, pre-linked binary files. SoftDevices can be programmed in nRF51 series SoCs and are downloadable from the Nordic website.
