1. Introduction ( BLE module 2 - pcb antenna )
The BLE module is used nRF51822 ultra-low power 2.4 GHz wireless System on Chip (SoC)
integrating the nRF51 series 2.4GHz transceiver, a 32 bit ARMR Cortex™-M0 CPU, flash memory,
and analog and digital peripherals.nRF51822 can support BluetoothR low energy and a range of
proprietary 2.4 GHz protocols, such as Gazell from Nordic Semiconductor.
Fully qualified Bluetooth low energy stacks for nRF51822 are implemented in the S100 series of
SoftDevices.
The S100 series of SoftDevices are available for free and can be downloaded and installed on
nRF51822 independent of your own application code.
