The TestE2 API provides a set of functions for programming, erasing, dumping and verifying the contents of an EEPROM device connected to a BlueCore chip. The API supports working with one or more (with gang programmer hardware) EEPROM devices, over a SPI connection. It uses a boot program, running on BlueCore, to perform the EEPROM operations, which is a faster method than that used by E2Api.
