Firmware development for Thingy 91

Thingy 91 is a LTE/BLE prototyping platform. [login to view URL] It can be programmed using Segger Embedded Studio and the following: [login to view URL] [login to view URL] There is sample code available that can help to get up to speed: [login to view URL] We want a firmware developed that can do the following: - enable iBeacon to advertise every 1 second (configurable) - detect other iBeacons (any, not only Thingy) that advertise in proximity - determine distance to other iBeacons that advertise (immediate, near, far) - record all found iBeacons for later submission: timestamp (at the time detected), UUID, major, minor, distance, GPS of the Thingy (itself) - record environmental sensor, light/color, accelerometers, GPS once per minute (configurable) Configurable parameters (at the time firmware is compiled): - URLs to submit recorded data to (default: will provide), to be done via HTTP POST - iBeacon advertisement interval (default: 1 second) - interval between sensor data recording (default: 1 minute) - interval between LTE data submissions (default: 1 minute) - iBeacon UUID, major, minor - enable/disable GPS data Additional requirtements: 1) When submitting to HTTP endpoint, do the following: - for each saved detected iBeacon submit: timestamp (at the time detected), UUID, major, Minor (of the detected iBeacon), GPS coordinates of itself (at the time detected)(only if GPS flag is on). - after all detected iBeacons submitted also submit (can be different endpoint): timestamp, environmental sensor, light/color, accelerometers, GPS data (at the time of submission attempt). - if endpoint is not available then save the data and re-try 2) I do have Segger Embedded Studio, I will need your source code/instructions so that I can compile/flash it into Thingy. 3) I want code that reads sensors to be a separate function that can be easily modified. Our production version might not have all the sensors so I want to be able to easily remove some code that would be irrelevant. 4) Comment the code Deliverables: Milestone 1 (75%): demonstrate that you can submit to our endpoint. I will confirm that the data is flowing as expected. Provide source code and instructions. Milestone 2 (25%): I will test the code, report any issues found. Milestone is complete when issues are fixed
