Sometimes you may find that the chipset is flash version or Rom version, but what is the difference between this?
CSR is a chipset manufacturer in the UK. There are many chipset models, which are divided into ROM version and FLASH version. The ORIGINAL ROM version has been fixed with firmware, and the developer can only rely on configuration tools to modify Settings and data, so the final differentiation of the product is relatively small. FLASH version chipset, it requires the developer to check the code, a bit more complex. Developer not only need programming but also need configuration based on the original SDK. But it is more flexible, it can be used for many different applications.
