We need to have small keyrings/watchsize/wearable IoT devices with various functionality to track and connect to both bluetooth and wifi. Especially BLE is of interest. Optionally to NB-IoT, LTE-M and LoRa Must have long standbytime, so understanding the concept of programming for ultralow power consumption is a must. You have to show, real experience and understand how to program use the Arduino IDE or Segger IDE. There is a number of dev./eval. Kits that will be provided. Can also use remote units connected to an laptop with Arduino IDE and Teamwiever. We might also consider a combination of nRF9160 and ESP32 for NB-IoT/LTE-M to Wifi and BLE Being able to implement the following sensors/peripherals in software, digital I/O, analog I/O, sensor over I2C, I2S, STI: 1) Environment sensors for air pressure, humidity, temp, and gas-sensor. Eg. BOSCH BME280 / BME680 and others. 2) Acceleration/compass component like: InvenSense MPU-9250, ST LIS2DH12, etc. 3) GPS, Glonass, Baidu, etc. position systems. 4) Calculation accurate distances by e.g. using HaverSine lib. 5) Calculate indoor position by calculating floor (e.g. heigh from barometric pressure), and triangular calc of wifi/BLI points. 6) Communicate using REST API, eg. aREST lib. 7) Communication over BLE Mesh architecture. 8) Present data on local LED display etc. 9) Present, store and retrieve data to/from the IOTA crypto network. 10) More to come. We try to break down project in small modules that should be possible to test and simulate individually. We can offer pament per well defined module and/or per hour.

Hi! I have experience working with Bluetooth Classic/BLE partucularly with ESP32 and in less part with nRF52832. We have used the ESP32 in a battery supplied product so keeping the current consumption at lowest possible level was a key point. It appeared that the ESP is quite power hungry IC even in low power mode or in sleep mode (running only the RTC co-processor). For a wearable device I may suggest to use the nRF products from Nordic semiconductors, they are way more power efficient tough more expensive too. I have my development tools, but can help you on your side as well, setting them up or adjust if needed. I can help you to add the necessary sensors and peripherals to your device as you've mentioned in your description.

Hi, I would like to know in detail about your project requirements so that I can have an understanding of your project. Recently, I have completed one project "Tag-N-Track", which is based on serverless APIs like Azure, Azure Functions etc. which provides the services like Smart warehouse, Smart Transportation, Smart Retail & Smart Delivery etc. I have used BT832 module and for the development, I have used NRF52 DK. Here, We are receiving BLE packets using BT832 module and send that data to ESP. The developed system is that much smart that It provides the details of available goods/inventory in racks and also provide the live shipping status of products according to their shipping vehicle. I am available for the project discussion. It will be appreciable if you come online for discussion. Please feel free to ask, if you have any query or concern. I will be happy to assist you.

@Sanlai

whatever your achievement now, it is not a small project I would like to learn something for the best of this stuff: 1/ what do you currently have (pcb, prototype, underway firmware, or only idea)? 2/ you describe carefully about the module itself, but nothing related to the UI. how do you intend to remotely observe the tracked info? mobile app, web server or any else? it therefore requires not only electronics and firmware development only but may be an app dev as well for the sake of process, those guys should work at the same place to synchronize the protocol of data. My team has enough members from pcb design, embedded firmware developer(MCU, sensor, peripheral controller, wireless module) and app dev (front end and back end)
