I have come across firmware a few times whiles reading. I would like to know how you can develop firmware in a practical way. How does knowledge of firmware development impact on one's employability? I would also like to focus on Bluetooth firmware development. Kindly point me to a resourceful website which will assist me learn everything there is to know about Bluetooth firmware development or firmware development in general.
How Do You Develop A Bluetooth Firmware?
Hello Jamie L Goines,   Firmware always developed in practical ways. This is not possible to make them in theoretical manner. Knowledge of firmware impacts a lot on employability, If you are going in product development organization. You can get full knowledge of Bluetooth firmware from https://www.lm-technologies.com/bluetooth-wifi-firmware-development/ this link.  Also you can visit on Wikipedia.
How Do You Develop A Bluetooth Firmware?
Generally, a firmware is the program that operates a device to make it work or to make it function. It is normally stored in a ROM drive integrated into the device and it runs automatically when the device is started. The program or the firmware is added to the device at the time of the manufacturing.
In a mobile phone, the firmware is the phone’s operating system. For example, if your handset is running on Android operating system then your firmware is the version of the Android mobile operating system. A firmware is not created alone like an ordinary application. It is always developed together with a device because that is its purpose.
A firmware is developed according to the design and capacity of a device. There are devices that allow updating of its firmware like Smartphones, tablets, and others. But there are devices that don’t require firmware updating like the firmware of a hard drive. Updating the firmware of a device doesn’t make it work faster.
The update only improves the performance and fixes the bugs that normally cause errors during operation.
