Module DESCRIPTION KEY FEATURES: BLE121LR is a Bluetooth Smart Long Range module targeted for Bluetooth Smart applications where the best possible RF performance and range are required. At +8 dBm TX power and -98 dBm sensitivity BLE121LR has best-in-class RF performance and can provide Bluetooth Smart connectivity up to 450 meters. BLE121LR integrates all features required for a Bluetooth Smart application: Bluetooth radio, software stack and GATT based profiles. and it can also host end user applications, which means no external micro controller is required in size, price or power constrained devices. BLE121LRBluetooth Smart module also has flexible hardware interfaces to connect to different peripherals or sensors. Although BLE121LR Bluetooth Smart Long Range Module is target for applications requiring high RF performance, it is still has relatively low power consumption and can be power using a standard 3V coin cell batteries. APPLICATIONS:             Smart home accessories beacon devices Health and fitness sensors Medical sensors iPhone and iPad accessories Security and proximity tags    Bluetooth v. 4.0 Single Mode Compliant o Master and slave modes o Up to eight connections Integrated Bluetooth Smart Stack o GAP, ATT and GATT o Bluetooth Smart profiles Best-in-Class RF Performance o Transmit power : +8 dBm o Receiver sensitivity: -98 dBm o Range up to 450 meters Low Current Consumption o Transmit: 36 mA (+8 dBm) o Receive: 33 mA (-98 dBm) o Power mode 3: 0.5 uA Flexible Peripheral Interfaces o UART and SPI o I2C, PWM and GPIO o 12-bit ADC Host Interfaces: o UART Programmable 8051 Processor for Stand-alone Operation o Simple Bluegiga BGScriptTM scripting language for quick application development o Bluegiga Profile ToolkitTM allowing the quick development of GATT based profiles Dimensions: 14.7 x 13.0 x 1.8 mm Bluetooth, CE, FCC, IC, South Korea and Japan qualified Bluegiga Technologies Oy 1 Design Check List Board edge • • • • Make sure that the programing interface (P2_, P2_2, reset) is available for debugging or FW updates Add test points for testing the current consumption Make sure that all the IO’s are in a known state Make sure that the layout under the antenna is done as instructed Min 17mm Min 17mm Metal clearance area Place large capacitor in parallel with the battery to reduce the peak current drawn from the battery The external DCDC converter will reduce the maximum TX power by ~2 dB The DCDC pin (P1_7) can only be used for controlling the external DCDC. The operation of P1_7 must not be altered by SW.
