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 worked with RPI3 with TI-sensortag(CC2650STK) to act as 6LowPAN (IPv6) Wifi router and connect other TI-sensortag(CC2650) and TI-launchpad sensor nodes as well as transfer data to 6LowPAN (IPv6) wifi router in MESH network.
As a part of this project, we have used few services like MQTT, CoAP to send the sensor node to server.
We have developed Cross 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.
