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
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 interfaced STM32 with serial port GPS/GSM modem as well as I2C/SPI interface with few sensors like ADXL345 accelerometer, RFID RC522.
We also worked with micropython on STM32F4Nucleo, ESP8266, ESP32 Board. we have interfaced ESP32 with serial port GPS/GSM modem as well as I2C/SPI interface with few sensors like ADXL345 accelerometer, RFID RC522, PIR sensor to sense the human and turn ON and OFF the night lamp accordingly and find tuned sensitivity and timing of the PIR as well as log the even on local server.
we have developed GPS tracking system using SIM908(Combo GPS+GSM Modem) and push the data to webserver along with device id, timestamp. We have customized firmware stack for SIM908 such that without any external MCU.
