YumaWorks is looking for a Net-SNMP Expert to adapt the net-snmp agent software to act as an SNMP front-end for YumaWorks' netconfd-pro server. - must be expert in C programming - must have worked with Net-SNMP code at the protocol internals level - NOT just porting Net-SNMP to a platform - NOT just implementing MIBs using Net-SNMP - must be familiar with SNMPv3 - should be familiar with RESTCONF or REST APIs The project is divided into 3 stages. You are bidding on Phase 1 only at this time. - Phase I: will support read-only MIB modules converted to YANG modules, using RFC 6643 - Phase II: will support complete MIB modules converted to YANG modules by hand to enable read-write and read-create MIB objects - Phase III: will support YANG modules that are converted to MIB modules. This will require multiple flat tables for the nested YANG data structures that SMIv2 does not support. Design and Implement Server Library for RFC 7407. For more details see the project functional specification: https://www.yumaworks.com/pub/dev/yumapro-snmp-func-spec.pdf. Internals of the NET-SNMP agent will be used and will need to be modified. The APIs that are for the OID-based GETNEXT will not be used.

Hello Freelancers, We're using CH376S USB Read/Write module to interface it to Arduino Uno for Data Logging Application. We also have EEPROM and RTC Interfaced to Arduino for storing the data locally and time stamping the data respectively. When the user connects Flash Drive it should generate a TXT file and store all the Data with time stamp in that file created in Flash Drive. This is few hours job for someone who is expertise in Arduino coding and have worked with CH376S USB Read/Write module before. Below is the link for Arduino code >> http://arduinobasics.blogspot.in/2015/05/ch376s-usb-readwrite-module.html

We are using the Mbed NXP LPC1768 development board and need a skilled person to write a USB interface on both the LPC1768 and on a Windows PC, so that we are able to send 256 bytes data telegrams. Today we have a HID driver that works, but it can only send 64 bytes/telegram and can only send 1 telegram per 1 ms. We need an interface that can handle at least 256 bytes/ms. On the PC side we are using Codegear RAD studio C++ builder, so the interface needs to be compatible with this. The right person should have access to a LPC1768 system and can then do the work from home.
