Compared to other Bluetooth chips ,NRF52832-QFAA There is an obvious characteristic that , SoC Yes 512KB Of Flash and 64KB Of RAM. And the last generation of products nRF51822 At the highest, only 256KB Of Flash, additional Flash and RAM Space also means nRF52832 It can support multiple protocols , And it can switch automatically at run time . Now there are many products that support the multi protocol feature .

nRF52832 Provides -96dBm Sensitivity , This data is very close to ti Of -97dBm, Higher sensitivity means more transmission distance . Improvement in this respect , It can make applications more diverse , Welcome to understand ！
