DESCRIPTION
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.
