We are a team of engineers having expertise on embedded domain. We have worked on several embedded linux/android SBC like Wandboard(IMX6Q), AM335x-sk, Dragon Board (Qualcomm), Pi0W, Pi2 & Pi3, Beagle Bone (Black & Green Wireless), C.H.I.P, Orange-Pi-Zero etc as well as Microcontroller Development Boards like Arduino, PIC and STM32
we have worked with various build system including make, busybox, buildroot, yocto, openwrt, android etc.
BLE, IOT and Wireless Technologies: 6LBR, contiki, openthread on CC26XX platform, TI-BLE stack(v2.20) TI-sensortag CC2650 (with debug_dev_pack and lcd_dev pack),TI-Launchpad, Keyfob(CC2541) and CC2540, CC-Debugger, NodeMCU(ESP8266), ESP32DevKit and nRF51 and nRF52
We have created custom linux distribution for few SBC with OTA firmware upgrade features.
--------------------------
We have developed Android Application for TI-sensortag(CC2650 ARM-Cortex M3) to push sensor data to AWS and developed python application for debian using bluepy and modified bluepy to set current time with sensortag, so that it can append timestamp along with sensor data.
we have customized BLE stack firmware to provide custom BLE Time Service for TI-sensortag(CC2650 ARM-Cortex M3) to accept the time from host linux system and set system time accordingly. We have customized TI-RTOS to accept the time in microsecond precision and maintain it in the system using RTC module.
As a part of this project we have collected the below mentioned sensor data to linux system,
