Hi there, I have many experiences in Raspberry Pi programming and development for various kinds of projects. I'd like to do your sat comm project using RockBlock module. I have all kinds of Raspberry Pi devices, from zero w to 3B+, and 4B. But I don't have RockBlock moduls. So I can buy a new one, or work on your Pi via remote connection. Thanks, Bhavya

I'm currently working as software developer for smartphone company. On my job, we work on Linux / Android developing device drivers / HIL (Hardware Abstraction Layer) for to work as modem (GSM, LTE) for Android based based smartphones. I'm also worked on pet project for a Lora Gateway based on raspberry pi, that gave some more experience with Raspberry. Due to my experience with embedded Linux and Raspberry PI I think I'm suitable candidate for you task.

Greetings to You, We are a team of 3 engineers into IoT & WEB Development. For this project we assume you are having RS485 Raspberry pi HAT and RockBLOCK modem with active connection. We will divide the project into 3 blocks. 1)Getting RS-485 Modbus data to the Raspberry PI 2)Pushing data to the Satellite Service Provider. 3)Displaying the Data. MODEMS(RockBLOCK) most of them work in Serial Port and also RS-485 bus converted to TTL needs Serial Port to work. RPi has only one serial port on header pins. We can overcome that, we will over come that by using USB to TTL. We estimate minimum 3 weeks to complete the work neatly. Except RockBLOCK all testing we can do at our end. RockBLOCK we will have to do it remotely with you. RockBLOCK works with proprietary AT commands, so we will have to learn and test that out first. We wont claim ourselves to be expert. Gokul is into web development for 8 years, George is into electronics for 10 years, Allen helps us with electronics. Waiting to hear from You. Thanks & Regards, ETrinity tech
