I am looking for someone to produce code for a microcontroller which is to act as a node in a wireless mesh network. The network will be used only for the streaming of low quality audio of approximately 16kbps. The node would need to decode the incoming audio stream (opus codec) based upon a channel selection by the user. The preferred microcontroller would be the STM32F4129 or equivalent as the node would also have a touch screen interface. Programming of the HMI would be a separately costed job. No preferred RF chip has been selected yet. Further details are available on request.

I am looking fro someone to design and program an HMI for a wireless mesh network node. The node will have a 2.4" touch screen with an SPI interface. The user will be able to select either one of two fixed channels (Channel 1 and Channel 2) or a third 'Home' Channel which would be selected by the user from a list of available channels. The menu structure is envisiged to be something like as follows: Page 1: Button to Select either Channel 1, 2 or Home Channel. Page 2 (or popup): Ability to set a channel as the home channel or select a fourth channel for listening. Menu structure as: Menu Level 1 (Nine options) - Menu Level 2 (Max 50 options) - Menu Level 3 (Max 20 options) The names for each Menu level or Channel would need to be editable and updatable by a remote connection so this needs to be borne in mind when programming. The graphics do not need to be fancy and a simple, clean, user-friendly interface is preferred. The processor would need to be an Arm Corte...

The network will be used only for the streaming of low quality audio of approximately 16kbps. The node would need to decode the incoming audio stream (opus codec) based upon a channel selection by the user. In any one network cell there would be a maximum of 10 selectable channels by a total of approximately 5,000 users. Each audio channel would be multicast over this network. The preferred microcontroller would be the STM32F4129 or equivalent as the node would also have a touch screen interface. Programming of the HMI would be a separately costed job. No preferred RF chip has been selected yet. Further details are available on request.

we are looking for a small company or freelancer who can design a circuit including microprocessor programming as per our requirement. it could be in form of strategic partnership as well. Below is requirement. 1. There would be a LED on a device (external device), the LED will blink after random interval of time. the solution has to capture every LED blink on that device and apply some login in microprocessor and send it over Wifi or GPRS network etc. The solution should be capable of connecting with wifi, GPRS etc network. The solution should have capability to connect multiple external devices to same solution chip or board. I will share more detail requirement document in further discussion. It is urgent requirement i.e. assignment will start immediately. We will have a V-CON before sign off the project and it is must. It would be an added advantage in company or individual is in NCR India but that's not a mandatory thing.

I have a Bluetooth Low-Energy beacon project that is based on a CSR1010. I have the beacon code working but the beacon function is currently broadcast (transmit) only. Now I need to add the ability to detect (receive) when another paired beacon comes into range. When another beacon comes into range it will trigger a PIO output. Need someone with lots of experience programming CSR BLE chips.

We are a young startup seeking to develop solutions around modeling and optimization for the oil & gas industry. I am looking for a self-driven, self-sufficient engineer who can do framing and modeling for us around oil and gas related problems that involve 'risk', 'probability', 'reliability', etc. Think of 'probability of failure' of equipment given a certain maintenance regime (might involve Bayesian or Markov networks), or 'probability of success' of an exploration campaign, etc. Monte Carlo simulation is one of the approaches that comes to mind also. With 'framing and modeling' the idea is that you deliver a solution, preferably in Java or a higher-level language such as Figaro, that can represent the business problems I will provide. Other solution spaces can be discussed, but ultimately the solution will need to run in Java. Our preference is that you are also a very good Java coder :-). The type of problem you might be given, is: 'you have 5 pieces of equipment with 'x' ...

I am looking for someone to make a very simple analog sensor wireless with a tiny, rechargeable digital i/o board. Able to communicate in real time with an arduino to output time stamped data. I also would like a simple graphical output (can be built in Processing or Python or whatever you wish). This should be a simple job for someone familiar with arduino and embedded systems. If this works out, there are other assignments which could be forthcoming.

Design all electronics for a sensor that use a voice recognition module. See attached PDF for manufacturer. Can use an alternative module, but needs to receive english words. This module uses pre-programmed typed words that systems listens for. Other modules need to be trained. Would consider other modules, but design fee needs to include simple method to activate voice training. When module detects words- data of this will be sent over TCP/IP via wifi to our server. It would send sensor ID, event, date, and time. Currently we a re using ESP8266 for wifi in other sensors. Good low cost. The sensor will need a method to connect it to the wifi network. Bluetooth or other very simple method. Creating the app to accomplish this should be included. All firmware to be included. The bid should include building 3 test units and all documentation for sourcing in for production in China.

We seek to develop a solar powered greenhouse automation system for small holder farmers in Kenya. The system should have 3 wireless sensors that measure temperature, humidity and soil moisture. These sensors also have small solar panels with an inbuilt battery to power it during the night. The approximate range of the sensors should be 300feet. The sensors are then connected to the main gateway which is programmed to receive impulses and convert them to messages to be sent to the farmer via SMS on their mobile phone using a GSM module. This enables remote monitoring of the greenhouse from wherever a farmer is just by simply texting the system. The system also using the soil moisture sensor should be able to automatically regulate the water channeled through the driplines by opening and closing the solenoid valve which should be solar powered too. This will ensure accurate and more efficient use of water channeled through the driplines. The farmer should also be able to self irrigate t...
