Write some Firmware for the Nordic nRF bluetooth chip -- 2

Hi we need 3 sets of custom firmware to be written for nRF51822 using the Nordic micro-ESB protocol that does the following: Device needs to find its satellite (Host2) and send that info to Host1. There will be one static Host1, about 2000 moving Devices and about 200 moving Host2's Devices need to find Host2 with the strongest RSSI value and send that information to Host1 roughly every 3-5 seconds. Devices need to transmit on alternating channels, in order for Host1 to better distinguish the Devices. Host1 needs to read the following information from every Device: UUID of Device + RSSI + Host2 UUID + Host2 RSSI Host1 then needs to output that data to UART port (Tx, Rx). We need firmware for Device, Host 1 and Host 2 1. Everything should run on micro-ESB protocol at 250kb link with highest radio sensitivity [login to view URL] don't need to establish connection (don't need acknowledgment from Hosts) between Host1 and Devices and just read data (Device UUID + RSSI +Host2 UUID + Host2 RSSI) from the Device's adverts. 3. Have a look at this post for information about micro-ESB [login to view URL]
