In need of an experienced embedded firmware engineer to work on BLE (Bluetooth Low Energy). The primary task will revolve around data transfer and synchronization. We have a task regarding range in the ble uart communication we are sending 100kb of data via ble uart using the 17.1 sdk example, increased mtu size, but we are not getting required range. If we flash the example in the dev kits we get more than 60m range in indoor environment, but in our code we cant get more than 20

Hi, I hope you are doing well I have read your requirements and I think we can provide solution for your project. We have working experience in Embedded development for more than 5 years and worked on various microcontrollers such as Arduino, ESP32, Nrf, STM 32. Talking about your requirement, we have worked with sending more than 100kb via NRF52840 using SDK17.1 for example image data. Some suggestions for your requirements, the range of Ble depends upon various parameters such as your PCB impedance, or number of BLE device nearby, or BLE advertisement or connection parameters. We can discuss further details in chat. Looking forward to hearing from you.

I'm an italian electronic engineer with more than 20 years of work experience. I work as HW designer and FW developer. As HW designer, I work in Altium, KiCad and Orcad and I have experience in development single MCU (Microchip PIC, ARM Cortex, ESP32) boards with several digital I/O (GPIO, UART, SPI, I2C, PWM,....) and some analog I/O. I design complete board: power section, MCU section, peripheral section,.... I design also boards with battery power; so I have experience in low power PCB design. I have also experience in commercial boards (Arduino, Raspberry, Beaglebone,...) shields design. I have also experience in bluetooth (both 2.0 and 4.0) PCB design. As FW developer, usually I work in C for Eclipse + GNU ARM GCC for different ARM Cortex M0/M0+/M3/M4/M33 manufacturers (STM32Fx, NXP, EFM32/EFR32 SiLabs, Nordic nFR5x, but I'm ready to learn new frameworks). I have also good experience with ESP32 in "esp-idf" framework. I work with both single task (bare metal) and multi task environment (ThreadX, FreeRTOS, RTX,...). I write code for low level driver (GPIO, UART, SPI, I2C, PWM....) management, for medium level (driver for sensor, MEMS, memories, fuel gauge, display,...) and for high level/final application, for bootloader and for OTA. I have great experience in cloud communication with MQTT/Azure protocol. I work also in "C code" commercial boards Arduino/Linux embedded commercial boards (Raspberry and Beaglebone).
