i am on a project which comprises of OTA concept. Would you please help me that how can i use OTA with 8051 MCU & CC2530 as I am having a module of sensor which consist of RF and communicate with a gateway in every 2 sec. The gateway is also having a MCU which consist of ethernet port and communicate with cloud server in every 15 sec. Now I need to understand how I can implement OTA as i am completely new to this and need to get it done asap. With the help of OTA we have to update the hex file of sensor module and gateway.
