Hell Vikram,

If you mean by "upstream the data" uploading them over BLE link to the device which performs OTA firmware upgrade then answer is "yes". Just write your custom bootloader/FW which is able to do it with your custom application on the other side of the link.

Can someone send me the example codes so that it will be easy to write custom boot-loader.
