Hi and thanks for studying this project: The project is to improve our company internet speed, mostly in uploading. We have a very limited ADSL connection in our place, with 8M DOWNLOAD and 0,6 M UPLOAD. -What I want is our Mikrotik that have 5 ports, to place 4 of them to WAN and one to LAN. -I want to sum all band'swith with all ISP in "WAN". -One of the "WAN" is a cellular conection 4G with data limit, This should make EXCLUSIVE USE of data ONLY for uploading. *The idea is to sum download speeds of ADSL, and sum uploads speeds of ADSL + 4G *Example. WAN 1 = ADSL 1, WAN 2 = ADSL 2, WAN 3 = ADSL 3, WAN 4 = 4G, LAN 5 = CONECTION TO PRINCIPAL SWITCH. *WAN 5 (4G) Must work limited or blocked with downloading. -At a fisrt stage, we would use only WAN 1(ADSL...

I need a mobile PBX application that lets my team place and receive internal calls entirely over our local Wi-Fi network. The app must run smoothly on both iOS and Android and register 51-200 extensions without relying on cellular voice or external trunks. Core functions I must see on day one: • Call forwarding, including unconditional, busy, and no-answer rules • Visual voicemail that stores messages locally and syncs with the PBX I have no immediate need for call recording, yet I prefer a codebase that leaves room to add it later. Whether you build the PBX side (Asterisk, FreePBX, 3CX, etc.) from scratch or integrate with an existing server, the result has to deliver reliable SIP registration, push notifications for incoming calls, TLS/SRTP security, and a clean user...

...remotely control my industrial equipment in the sense of keeping an eye on its live performance data from anywhere. The machinery is already fitted with basic IoT-ready sensors; what is missing is the cloud-to-device bridge and a clean user interface where I can watch throughput, temperature, and fault codes in real time. Here is the flow I have in mind: • Edge device pushes sensor readings via cellular data to a secure backend (MQTT or HTTPS—use what you are most comfortable with). • Backend stores, normalises, and exposes that data through an API. • A web or mobile dashboard pulls the feed and displays key performance metrics with alerts when values drift outside preset thresholds. That monitoring dashboard is the first milestone and the only compuls...

I’m working on a project with the AVR-IoT Cellular Mini (Sequans Monarch 2 modem), where I modified the Arduino-based firmware myself to periodically transmit GPS latitude and longitude data to my backend (BE) over HTTPS. The objective is to send GPS data (latitude, longitude, and timestamp) to a REST API endpoint at a defined interval and confirm that the data is successfully received and visible on the backend. At the moment, I’m blocked by a TLS issue while attempting to configure the CA certificate for HTTPS. When I try to add the root CA certificate (ISRG Root X1 – Let’s Encrypt) to the device/modem, I get an error that says: “CA certificate input too long” Because of this issue: • The TLS handshake fails. • The HTTPS request ...

...and need a full-fledged PCB layout that is ready to send straight to fabrication. The schematic is not fixed yet, so I’m relying on your board-level expertise to translate high-level requirements into a clean, production-ready design. What I already know • Form factor: credit-card sized (roughly 85 × 55 mm, single board). • Core: a low-power MCU or module capable of handling multiple digital and analog inputs. • Future-proofing: headers or pads for common temperature, humidity, and pressure sensors as well as optional wireless modules (Wi-Fi, Bluetooth, or cellular—final choice can be discussed once power budget is clear). • Power: ability to accept both rechargeable battery input and external DC (buck/boost circuitry with reverse-pol...

I’m working on a project using the AVR-IoT Cellular Mini (Sequans Monarch 2 modem) where I customized the Arduino-based firmware myself to periodically send GPS latitude and longitude data to my backend (BE) over HTTPS.

I’m running an InHand IG502 cellular gateway and need a focused Python add-on that exposes the unit’s current RSSI (raw dBm) as a holding register inside the built-in Modbus server. The immediate aim is simply to monitor signal quality; once the value is available we will pass it through our existing RS-485 link into the DNP3 layer of the external SCADA. Key points you should know while coding: • Device: InHand IG502 (OpenWrt-based, Python 3 available). • Output format: raw signal strength value, no scaling or percentage. • Register must be readable via Modbus-TCP and Modbus-RTU so I can map it downstream. Byte order can be little-endian; just document what you use. • Communication onward to DNP3 happens on my side, so the script only has to po...
