I need to design a small data collector. No sensors of any kind is need. The data is collected by network using SNMP and sent to a remote server for further processing and storing. I already have a "proof on concept" running in RB pi with code in python. However RB pi is too much for the final product and too expensive for production in medium scale (about 600 units/year). I am not sure if arduino is the ideal platform either, but this is up to you. So I am looking for someone that could "port" the code to some tiny hardware/controller. The device is intend to scan the local network looking for network devices with a specific MAC address prefix (the manufacturer prefix). For each device that meet that criteria it should use SNMP to GET a fixed set of OIDs in numeric form. Then it should send the SNMP answer/response (also in numeric form, "as is") to a remote server using HTTP/POST. Therefore as all SNMP GET arguments and answer are plain/raw numeric oids, no need of a MIB translator. No MIBs envolved at all. After a few minutes it should repeat that cycle: "scan; snmp GET; http POST" forever. Add to this the snmp TRAP capability. The devices I am monitoring by SNMP could send to this data collector a SNMP trap to inform of an abnormal event has ocurred. In this event, the data collector must send a diferrent http POST message to server. The data collector must have at least 2 network interfaces: RJ45/Ethernet/cabled and Wifi/wireless interface. A web configuration interface (multilingual: English, Spanish, Portuguese at least) is need to the user: 1) determine which network interface is active: only cabled, only wi-fi, or both active 2) define the network configuration for each interface (DHCP/fixed IP; input of SSID and password for wifi interface, etc) 3) give some feedback to the user of the current operation of data collector. Whatever is the configuration choosen by the user using the http/web interface above, the data collector should keep that configuration in a non-volatile memory (E2PROM, NVRAM, whatever) so it may apply that network settings after a cold restart. Also, a physical reset button is needed to reset the network configuration back to a default, erasing the stored network configuration on non-volatile memory. Some led status indicators are needed so someone can quickly check if the data collector is running ok or it is in some error condition (network unreachable, no devices found, server error, etc) A power supply, a plastic case, an external antenna (for better wi-fi signal) and a method to update the firmware are expected.

Hello, I am software developer with enough experiences on C/C++, SNMP, Raspberry Pi3, Python. I can work by full time for your project and trying to satisfy the requirements. I am designing the project from scratch and structure it well. I am following the project's design process exactly, and if any error is found, fix it within 24 hours and provide maintenance free of charge for a month. Client's idea + Programmer's good coding is the perfect result, this is my idea. I want to keep long-term relationship for customer so I want to give the nice result. C/C++, SNMP, Raspberry Pi3, Python is very powerful programming language and I am majoring on it for long years. If you want the perfect result, please contact with me.

Dear Sir, I am an expert with more than 15 years of experience in Firmware development, prototyping, PCB Layouts and Product design. I have worked with 8-bit, 16-bit and 32-bit MCUs developing ultra-low power designs with complex algorithms. I have worked for Smart Grid, Wireless, automotive and Communication systems. Look into my previous reviews. I have already developed Simple Network Management Protocol (SNMP V1.0) on PIC18F over WiFi. I have developed TCP / IP Stack for the SNMP. SNMP is an application layer protocol (like HTTP) and works on network devices (like printers, scanners and routers) to acquire their time of service and other parameters using OIDs. I really like your idea about RPIs and Arduinos. They are good for rapid Proof of concept, but these devices are not for custom hardware. I work professionally and never use these. The best single chip solution for your product is PIC18F97j60. However if you want to implement SNMP V3 (with security and encryption) then we shall move to 32-bit MCU (either PIC32Mx or Cortex Mx). I assure you the best prototype (a working one in only 1600 USD), with the following milestones. BR Talha

Hello Friend, i know what you need. You need a $2 micro-controller. It will do everything, connect a sensor to on-board & viola! Very cheap to produce, the code will be all C or Assembly. I have more ideas, shoot me message if you are interested. PLEASE DON'T USE RASPBERRY PI or ARDUINO TOO EXPENSIVE for what you need to do with the device.
