I'm developing an application based on QN9080. This application should read values from two I2C sensors and store in a buffer in a Flash SPI memory. At 15-second intervals it should send the stored data, arranged in formatted packets, via BLE to a Smartphone application. So, I'd like to write the QN9080 software in the simplest way possible. I already have the base application running with FreeRTOS, performing the readings of the sensors, writing on an OLED display and storing in flash memory. I need to implement BLE communication without using the OSAbstraction layer. Can anybody help me ?
