I need a dependable mystery shopper who can work entirely from home to evaluate a selection of retail stores. Your mission is to recreate the full customer journey online or by phone—without physically entering the premises—and then report back on two key areas: • Customer service: How friendly, knowledgeable, and responsive is the staff during online chats or calls? • Product availability & display: Is the information about stock levels, sizes, colours, and promotional placement presented clearly on the website or over the phone? You will receive a brief for each assignment detailing the brand, scenario, and any compliance notes. After completing the interaction, deliver a concise report (Word or Google Docs is fine) that includes time-stamped notes, any...

My Zephyr setup inside VS Code suddenly stopped recognizing its West Workspace and, at the same time, the BLE fields in the NUS sample keep snapping back to Zephyr’s hard-coded defaults. I already tried the normal “Initialize West Workspace” button in the nRF Connect extension, but it still shows “Not initialized”. Here is what I need during a live screen-share session (VS Code GUI only—no terminal, PowerShell, or Linux commands): • Walk me through restoring a healthy West Workspace so the nRF Connect extension sees all boards, SDK paths, and build configurations again. • Point out exactly which files or overlay/kconfig entries control the BLE advertising data—device name, company name, model name, version, etc.—and show how t...

I am looking for an experienced electronics/IoT developer to build a **working prototype of a 4G SIM-based security camera and a simple mobile app**. The camera should work without Wi-Fi and connect to the internet using a SIM/4G network. ### Prototype Requirements * Camera with live video * 4G/SIM connectivity * Microphone + speaker for two-way communication * Battery powered * USB-C/external power or power bank support * Remote viewing from a mobile app * Basic camera controls * Simple backend/cloud connection * Prototype should support the concept of having multiple cameras at one location For the first stage, I am **not looking for a production-ready/custom-manufactured camera**. Commercially available development boards/modules can be used. The goal is to build **one complete wor...

I'm seeking an experienced IoT developer who can create a hardware device with a digital display. The device should operate offline, providing straight output based on programmed inputs. Key Requirements: - Hardware: - Digital display output - Programmed to do calculation. - App: - Display input data and calculations from the hardware - User-friendly interface Ideal Skills: - Experience in IoT hardware development - Proficiency in app development - Strong programming skills - Ability to create offline operating systems Please provide examples of previous work and a brief outline of your approach.

Description: I need a mobile app developer to build a simple prototype app for a clip on spectrometer device that detects fake drugs and food. The device connects to a phone via Bluetooth and sends 18 channels of spectral data. The phone camera captures a Raman spectrum image. The app compares the data to an offline database and shows a simple Green (genuine) or Red (fake) result. What the app needs to do: Connect to an ESP32‑S3 device via Bluetooth Low Energy (BLE) Send a "START_SCAN" command to the device Receive 18 numbers (NIR spectral data) from the device Open the phone camera to capture a Raman spectrum image Compare both data sets to a local offline database Display a result: Green (genuine) or Red (fake) Save scan history locally Requirements: Experience with...

The lock is TuyaMCU based and uses WBR3 Wifi/BLE module which is based on RTL8720CF; TUYA IOT SDK V:2.3.1 rtl8720cf_common_lock_ty:1.1.16 pid:umca8uiv2203ua3k firmwarekey:key5943jddfsyeu3 v1:1.1.16 v2:1.3.9 Tuya-CloudCutter wont work as its not entering AP mode. Flashed OpenBeken FW, but cant set properdpIDs Thanks. I’m running a Tuya-based smart lock that currently relies on Tuya’s cloud, and I want it to function entirely inside my LAN. Lock, unlock, status, battery level—everything has to stay, but without any call home. What I need is solid API integration work. Whether you reverse-engineer the existing Tuya local protocol, pull the device keys, or wrap native commands in MQTT/HTTP, the outcome should be a clean local API I can hit from Home Assistant or a simple...

Objective: Mapinger currently provides a CRM-based platform to create and manage indoor floor plans, profiles, locations, tags, and navigation. The next requirement is to introduce real-time indoor positioning, allowing a user's current location to be detected inside a building and displayed on the Mapinger indoor map. Target experience “Open Mapinger → Indoor map loads → Your live location appears → Mapinger shows where you are and guides you to your destination.” The system should support multiple positioning technologies, primarily: Bluetooth Low Energy (BLE) Beacons Wi-Fi-based positioning Potentially Hybrid BLE + Wi-Fi Future support for other technologies such as UWB 2. Business Requirement The current Mapinger system tells users where places are...

I need a speech-driven virtual assistant that lives on iOS, Android, and in a lightweight web client. Its core jobs are threefold: handle calendar scheduling with smart reminders, fetch facts or real-time information on request, and trigger common home-automation actions such as lights, thermostat, or security scenes. I am looking for an end-to-end build that covers natural-language understanding, speech-to-text, text-to-speech, and a small but polished UI shell for each platform. You are free to choose the NLP stack—Dialogflow, Rasa, or a custom transformer model—so long as latency stays low and the solution can scale. For voice, feel free to tap into native engines (Apple Speech, Google Speech, Web Speech) or a cloud provider like Azure Cognitive Services if it speeds deve...
