I have a Bluetooth Low energy device (BLE) device from Nordic nRF52811, this is complete soC contains the controller as well.
I need to use its Bluetooth only, then whatever I receive "DATA" on its Bluetooth module I need to transfer it to another Microcontroller outside its module
My question is: does this BLE module contains the firmware for Bluetooth, and microcontroller or do I need to write it separately? Like, the driver for BLE, SPI interface ?
nRF52 chips normally come with the flash completely empty, without firmware. You can find software and guides at Nordic Semiconductor's website.
