Hardware / firmware design. I have developed a POC for a bike box where you can open a bike box (kind of schelter with 5 bikes) by an RFID card. Access is checked from a remote server, (directly or in some cases by a whitelist checked every 24hrs). This POC works fine, but now we want to go a step further, and have our own device instead, as we have some specific requirements. For the software / firmware it would be good if we could work on an arduino based system, so that in case we want to change something in the source it can be done without having to redesign and develop everything. System requirements: - 3G /4G (so SIM slot) - Wifi - BLE - RS485 input (for the card reader) - Output: 6 outputs BUT should be possible to extend to 20 outputs we can control individually Software requirements The software is in fact rather easy. We need to - rfid card is presented on the reader (RS485) and the card number is checked internally in the whitelist. If correct a certain output should be triggered (5 seconds of power) - Rfid card is presented but this time the card is send over mqtt towards our server. Server sends back a command on mqtt and then an output is opened - Device should send keep alive with battery status every hour - BLE : command is send over BLE to open a certain door Wifi on the device is used instead of 4G to have the internet connection. I am looking for someone that can provide the whole package and assist me with a prototype. If you can generate prototypes that would be perfect too, but otherwise I know the local companies that can do that part.

Hi wouterdr. I have just read your requirements in detail and became interested in this project. My specific skills are electronics and electrical engineering. I developed a digital relay protection device by relay and I tried to communicate between device -HMI , device-PLC and device-PC I've tried manipulating Wireless communication by Zigbee and RF, Rs485 communication, 232 communication, and USB communication according to the MODBUS communication protocol and LCD control, SCR control and IGBT control, etc, with Microcontroller, Arduino and Raspberry Pi, etc. I use programs such as Altium Designer, Proteus, mikroC PRO, Pic c, Mplab, HI-TECH, Keil, python and Qt etc. I’m also full stack web developer. I am confident I will be able to carry out this project and I am ready for your test at any time. So, I hope we will discuss more details about your project through chat. Then, I'll do my best for you and I'll give you the best results within the specified deadline. I am a person who puts credit first. Looking forward for your response. Best Regards.

Dear Client, we can confidently build an Arduino based PCB design + Firmware incorporating your rest of requirements and productize your bike box POC. We can even manufacture and assemble the prototypes and provide you the working tested units. Please find comments inline to your requirements. System requirements: - 3G /4G (so SIM slot) -> Feasible by integrating LTE/NB-IoT/CAT-M1 module over UART/USB on Arduino. We have worked with cellular modules in past. From certifications viewpoint, you may need to go for PTCRB if you go with AT&T or similar career. The other option is to use MVNO. SIM slot will definitely be there, however, the other option is eSIM. - Wifi -> Feasible - BLE -> Feasible - we can use Wi-Fi + BLE combo module such as ESP32 based module. There are definitely other better options in terms of power saving and performance. - RS485 input (for the card reader) -> Ok, there can be other interfaces possible, so is there any specific reason to mention RS485? - Output: 6 outputs BUT should be possible to extend to 20 outputs we can control individually -> what are these outputs supposed to drive? In addition, how is the unit to be powered on? Will it be a battery powered or will it take power from bike battery/bike engine? Few questions on software side too, but here max characters limit is over so we can discuss over chat. Timelines and cost will then be quoted clearly. Best Regards, Rahul Shah
