NO COPIED CODE WILL BE ACCEPTED (ALL LIBRARIES USED MUST BE SELLABLE FOR INDUSTRIAL USE) We are making a wireless relay system to exchange messages, statuses, etc. between relays (the 'nodes') using the BLE mesh network. We would like to implement the mesh network communication between multiple nodes using Nordic Semiconductor nRF52840 ([login to view URL] 3dJ). The mesh network should contain any number of basic/normal nodes and one master/controlling node. Deliverables [login to view URL] of MESH Topology for the successful implementation of covering a large area. [login to view URL] able to control the state (on/off) of the relay module attached to the Nordic chip (nrf52840). [login to view URL] between nodes (regular and master nodes) [login to view URL] able to control the intensity of the appliances that are connected e.g., Lights, Fans, etc. by both from the app and the physical potentiometer attached to the switchboard [login to view URL] app should know the state of the appliances (on, off, and level of intensity) e.g. Sonoff style convention ([login to view URL]) [login to view URL] able to track temperature, electricity usage, etc. to allow users to keep track. [login to view URL] able to introduce new nodes within the network along with new relays if required (this should be possible in runtime after the device has been implemented in the setting). ...

Hello, I am a Senior Hardware developer. I have been working as a embedded hardware designer for 10+ years. I had developed several similar projects using the various microcontrollers such as STM32F1/2/3/4/7xx, PIC16/18xx, Wifi(ESP32, ESP8266), Zigbee, BLE/Bluetooth, Atmega, and the various Sensors. I can review and find out the mistake in your current design. And help you from designing to produce the small production. I have many experiences of schematic and multilayer(2~8 layer) PCB design with various BGA core(Cortex series, A series, FPGA ...), DDR3, DDR4, Ethernet,eMMC, HDI, WiFi. I am sure I can complete it on time with high quality. In that sense, I think I am the suitable persons you are looking for. If you give me a chance to interview, I'll explain in more detail and I'll do my best for you. I will work hard and hard to complete this task successfully. Best regards.
