Nordic nRF51822

Hello, We are looking for some one to code nrf51822 for us. Below is scope of work 1- nrf51822 is Having ADC input and a UART rx and tx wire that we send to some other chip, not in scope of this work. 2- nRF51822, waits and listens for commands from Mobile App. Mobile App are both iOS and Android. 3- Basis commands, nrf51822, writes some output on UART tx and starts sampling ADC channels. 4- nrf51822 starts sending results of ADC channels, ober the BLE to the Same Mobile app, which are sending him commands. 5- Battery service is to be build up. Battery is connected on seperate ADC channel, which the nrf51822 has to keep sending all ways 6- Device ID needs to be sent on seperate service. 7- DFU - Over the air, firmware update functionality has to be added, so that our Mobile app can perform field update on the nrf51822 firmware ( app only ). We already have ADC code writtem so we will share the PIN and ADC code. Rest of the things have to be developed. Thanks, FRAGT1
