We need someone with good knowledge about Nordic Semiconductor NRF24LE1 to write firmware in Keil for a prototype that will communicate between sensors and actuators all with NRF24LE1 and a master with NRF24LE1 and ESP8266 communicating with MQTT. PCB's and prototypes are finished and ready. Circuitry and all supporting hardware documentation are available.
Only bid if you really know NRF24LE1 and can work fast . This first project is just a small start to find the right person, if things works out fine it can be much more work.
