Introduction Of The Over The Air Update (OTA Update) This article discusses about how to update a microcontroller’s program/chip firmware over the air (OTA Update). With increasing the source code lines and the firmware/program size, probability of errors will increase. So the application of OTA update is usually in smart circuits with larger firmware size.…
