We are looking for a embedded C developer who can develop us a Modbus - MQTT gateway for our existing boards built on ESP-32. The software should have the following features: - The Wifi and MQTT should be configurable by the user - Interface OLED - Should be able to add multiple modbus registers to log data and send it to MQTT. All the implementation should in C (ESP-IDF), we are not looking for arduino code. We already have the boards ready and a documentation of it is attached below. The document includes a long term plan and would love to work long term with the right person. If you are experienced enough we would love to work together, while bidding start with "Its Modbus".!

It's Modbus :-) though actually this is Pavel here. 15+ yrs. of experience, 8 of them in embedded/IoT/SmartMetering area. Which version of MQTT are you going to support (do you need MQTT 5 features)? Have you already decided on MQTT topics structure, should it be configurable/configurable on the fly? I see some words regarding MQTT configuration, but they may mean just brocker IP/port configuration. Do you need Modbus TCP support (you have Ethernet port, after all, why not? may be a good extra feature). There's a lot of other questions to ask/discuss, but the size of prposal is limited, so please drop me a line, and I'll ask these ones in PM. Thanks, WBW, Pavel.
