Hi,

Please download the kw36 sdk. It has many useful document about the ble development.

In directory 'docs\wireless\Bluetooth', the 'Bluetooth Low Energy Application Developer Guide' introduce the otap. You can also refer this link

hello, thank you for the reply.

i read the Bluetooth Low Energy application developer guide and i not found any section for android implementation. Furthermore not all informations are clear. For example, i don't understand the correlation between srec records and image file format: S0 record contains the name of file and S2 records tlv byte not correspond in my srec files. I can't find the information displayed into iot toolbox Like "File name" or "File version". Why file version is hex value?

Hi,

The document describe the OTAP protocol. You need this to develop your APP. Of course, it doesn't have the description about how to develop APP.

You can also refer this article. This article tells you about the OAT header. The file name and file version is included in OTA header. When you use iot tool box, if your image doesn't have the OTA header, the iot toolbox will add this for you. If you want to set the ota header by yourself. You can use the test tool.

Have a great day,
