It is aimed to manage our device located on the roof of the building by connecting directly from the phone application using the Bluetooth protocol from a distance of approximately 200 meters (Open Area). (Devices are suitable for external antenna installation.) Work packages expected from Freelancer; 1. Firmware for nRF 52840: • For nRF 52840 SoC hardware (can be nRF 52840-DK development board), firmware must be prepared using Segger Embedded Studio and nrf SDK. •Bluetooth connection speed can be any of 2 Mbps, 1 Mbps, 500 kbps or 125 kbps. • For high distance, the nRF 52840 firmware should be designed according to the maximum output power (+8dm tx). (The communication distance between the phone and nRF 52840 board is expected to be approximately 200mt.) 2. Phone App : (Led Blynk Test App) • With the phone application, nRF 52840 modules within the 200mt open coverage area should be scanned and listed. • A connection will be made to any nRF 52840 module from the list and the LED TEST BUTTON within the application will be pressed. When this button is pressed, 24 Byte data will be sent to the selected nRF 52840 module, and 24 Byte data will be read from the application as a reply. Note: It is planned to use the nRF52840 SoC/module, which we think is the most suitable for this project. ( That's why we provided ourselves an nRF52840-DK (Development Board) and an nRF52840 USB dongle so we can experiment.) nRF 52840-DK : [login to view URL] Project Test / Acceptance and Payment: We assume that the user phone to be tested in this project is the minimum Bluetooth 5 and above. The result of the project will be tested with the phone list below and a minimum of 200mt (Open Area) uninterrupted connection will be expected. • iPhone XR • iPhone 11 • Samsung Galaxy S10+ • Xiaomi Poco X3 NFC Accordingly, the developer(Freelancer) will undertake that there will be a minimum 200m distance connection between the Phones listed above and the nRF52840(client Board) before taking the job. Otherwise, the project will not be successful. In this case, we do not accept the payment

Hi, I have more than 6 years of embedded and it system development experience. i have worked with major microcontrollers in BLE domain. i have hands on experience with NRF52, EFR32, PSOC, ESP32 etc. MCUs. I am also experienced in flutter for mobile app development. just in case you need a PoC app to test it out. For long range you have to relly on lower data rates for sure but that shouldn't be a problem since your datarate is low. Besides NRF32, I think EFR32 is also worth considering for your project requirements. Looking forward to have a detailed discussion with you Thanks & Regards

hello sir, how are you. I read your proposal and i am interested in this project. I worked with NRF52832 and NRF52832 SDK. Therefore it will be easy to work on NRF52840 and its SDK for me. I am an Embedded engineer (ARM, PIC, AVR, Arduino, SOC BLE (bluetooth) chips, ZigBee, WiFi, GPS, LED, LCD display etc.) and PCB designer (Altium, KiCad, Eagle), 3D Modeling. You can check my profile for more information. I can do this project as per your requirement. I hope you will consider me for this project. I am waiting for your reply...... thanks with regards Preetpal Singh

Hi, I have more than 9 years of experience in embedded design and development. I have expertise in IoT products developments using various wireless technologies like Wi-Fi, BLE, Cellular, GPS, Lora etc. I have been working on Nordic Platform since 6 years and I have developed applications on difference BLE SOCs i.e. nRF51822,nRF51844,nRF52832,nRF52810,nRF52840. I have experience of difference BLE profiles i.e. peripherals, broadcaster, central, beacon etc. Furthermore, I have a team for mobile application development and cloud app development. We have already developed BLE based mobile applications for both android and iOS. I have nRF52832-DK and nRF52840-DK board for testing firmware. Let's have discussion, so I can show you demo of apps. Thanks. Jitendra
