This blog is the sequel of blog “Bluetooth technology”. In the previous blog “Bluetooth Technology” we discussed in detail about the basics of Bluetooth, how communication takes place and how are they classified. In this blog, we will describe in detail about various parameters and options that are available in each while designing a Bluetooth Low Energy (BLE) based IoT device.
Today we find numerous BLE enabled IoT devices emerging in market with typical applications such as wrist wearable in healthcare, Beacons & tags in retail and many more in home automation, industrial, automotives etc. In all these domain applications, most important criteria’s while designing the device are as follows
In the following sections we will discuss in detail what are all important for selecting a BLE SoC in building a BLE based IoT devices and multiple options that are available to choose from.
BLE SoC is an integrated chip that includes both the Microcontroller and BLE transceiver. They are also named as wireless microcontrollers. The microcontroller part includes the core, flash memory, RAM and peripherals such as GPIO, I2C, SPI, UART, timers, ADC, etc. BLE part includes RF transceiver compatible with BLE specifications (usually v4.0, v4.1 or v4.2). In addition to BLE, some of the SoC also supports IEEE 802.15.4 standard compliance which is a standard that defines the operation of low-rate wireless personal area networks (LR-WPAN). It is the basis for the ZigBee, MiWi, Thread etc.
Following are the selection criteria for BLE SoC,
Following are the popular BLE SoC part numbers available in the market from various semiconductor manufacturers,
In addition to the SoC, for a device design that require only BLE connectivity, there are various modules available. These modules will include the SoC with inbuilt chip or PCB antenna. All the necessary peripherals will be brought to the expansion connectors and the power can be fed through the same. The communication with the BLE module will be an I2C/SPI/UART interface. The main advantage of those BLE modules is that, they are fully tested and compliance certified.

In this blog, we will discuss in detail about the camera interface and data flow in Jetson Tegra platforms and typical configuration and setup of a MIPI CSI driver. For specifics, we will consider Jetson Nano and Onsemi OV5693 camera.
In this blog, we will explore the scope for No-Code and Low-Code development for embedded systems and how Flint tool can help realize the same for this field.
Now a days in 2022 due to technology growth, a product is having multiple features/use cases and it has been upgraded for bug fixes and new features in the interest of customer/end.
In any vehicle, the instrument cluster forms a critical part as it is the face of the vehicle that reflects the current state.
