We are developing a PoC for an IoT solution using state of the art hardware. An important deliverable is to configure the PoC hardware correctly so it communicates efficiently with the cloud solution and between devices. The cloud solution is an AWS-based MQTT broker that connects to InfluxDB and/or Azure IoT, but this may be re-developed to connect directly via MQTT using Azure IoT DPS and Azure IoT Hub. There will be two types of hardware in general. Some LTE/NB-IoT gateway autonomous devices and some BLE devices that will need gateway devices to connect to the cloud. Units must be configured to send sensor data to the cloud solution in the correct frequency. High-level tasks includes, but are not limited to: 1) Development of new and/or changes of existing firmw...

Professionally, Electronic Circuit Design and software will be purchased. Altium designer will be used for circuit design. Quectel EC200U Mini PCIE or Guson GM196 Mini PCIE will be used as GSM Module. Nuvoton or ESP will be used as the processor. With the software to be developed on the processor, MQTT protocol will be used over the GSM Module, a telemetry circuit that can communicate with UART and MDB protocol and which can be updated remotely will be made. We expect the project to be completed within 15-20 days after the start of work. We will work with Professional and Senior engineers. Beginners should not bid. Write OE at the beginning of your offer for fake applications
I need a sample project developed with C# and .NET core to subscribe for mqtt topic (using mosquitto broker) and store this data in MSSQL or Postgres.
Prerequisites ・Must have experience with PHP, SQL, and MQTT ・This project is related to IOT. 【What we want developers to do】 1. Debugging the previous version (check the database, check the specifications, and fix any bugs) 2. Add new functions (search, creation of tables) 3. Add support: already have functions, but add a store (create invoices, send emails) 4. Implementation of asynchronous processing of sending/receiving by MQTT (MQTT may not be implemented) Current status There are no specifications, so we have to start by analyzing the DB. After talking with several developers, we will decide who to request. As our initial cilent wants to check developers skill, ※YOU MIGHT NEED TO SEND YOUR WORK HISTORY AND SKILL SHEET.
I created a Code for a Wallbox, so that Hotel Guests are able to use their Hotel Room Cards to start a charging process. The Code basically checks the validation of the Room Card, reads the Room Number of the Card, and transmits Room Number and the authorization to the MQTT Server. The Charging Station does the rest and sends an Email at the End. The Code works, but I have some hickups with collecting the mqtt Data of the current charging Rate and total Amount. Now I thought if it would be possible to use it with Tasmota, so I would be able to edit the Script from Remote, and don't have to flash the pcb onsite if changes are needed.
I am looking for freelancer who can develop IFTTT type rule based MQTT scheduling of commands . The Application is similar to ewelink App where user can define scenes . Eg Turn on lights at 4am . And mqtt will send command to the device Eg When motion detected turn on alarm for 10 sec These rules will be dynamic and will be set by end users based on the devices which he owns . For Inexperienced developers this will be super tricky so please ensure you are ready for some nasty logic execution and code writing . Preferably 10+ years are suitable who have MQTT , ANDROID , NDK EXP

I have a MQTT broker setup in AWS (IOT-Core). I need to read/subscribe data from third-party MQTT broker (with username, password, 2 topic names) and put/publish the data in my IOT-Core. I'll provide access to my AWS account. As I understand, this will take less than 1 hour for the experienced resource once login credentials are available. I would prefer to do it in MS Teams meeting in the screen sharing session. Thank you.

I have seen MQTT client projects on GitHub () I need you to create or adapt a solution that will connect to a specified MQTT server and display the data based on the JSON configuration file (see the attachments). I also attach a screenshot from our mobile app that does the same thing, so you can get an idea what is to be displayed and in what manner.
the project involves writing code to store and send lat & lng data via MQTT
