Hi Nordic Team,
Please suggest any program(API) for extracting company id and device id from manufacturing data.
The terms (Company ID and device ID) can have different meanings in different contexts. I am not sure which context you ask about, but there is nothing embedded in the nRF5 IC's themselves that has that term. I suspect you are referring to the Bluetooth company ID that is registered with the Bluetooth SIG and typically associated with manufacturer-specific data in the advertisement packet, and this is something you set in your firmware.
For clarity: the registers NRF_FICR->DEVICEID and NRF_FICR->DEVICEID contain the nRF52832 IC's "Device Identifier". However this has absolutely nothing to do with advertising data.
patil_akash As far as I know there is no API for extracting the company ID from manufacturer specific data in BLE advertising packets on the nRF series. The advertising data format is very simple though, why not parse it yourself? See e.g. this thread for more info.
