Chip Antenna Cansec Low Cost WB822D Nordic NRF51822-CEAA 100M Wireless Mini Blue Tooth Module 4.2 Ble For IoT
1. WB822D Module is designed based on nRF51822 RF SoC chip of NORDIC company.
A method of communicating data in a Bluetooth™ low energy (BLE) module is provided. The method includes modulating an outbound communication signal into a modulated signal with a particular modulation scheme based on a modulation type, and transmitting the modulated signal to a remote device via a wireless communication connection associated with the modulation type. The method also includes receiving an inbound radio frequency (RF) signal, determining if the inbound RF signal is associated with a modulation type, and demodulating the inbound RF signal with a particular modulation scheme based on the modulation type if the inbound RF signal is determined to be associated with a modulation type. In some aspects, the inbound RF signal and outbound modulated signal have symbol rates of 2 Megasymbols per second. In some implementations, the method includes switching between a legacy BLE system and an enhanced rate BLE system.
