Microchip Technology recently launched next-generation Bluetooth Low Energy (LE) solutions intended for Internet of Things (IoT) and Bluetooth Beacon applications: the IS1870 Bluetooth LE RF module, the IS1871 Bluetooth LE RF module, and the BM70 module.
The Bluetooth LE devices include an integrated, certified Bluetooth 4.2 firmware stack. Data is transmitted over the Bluetooth link using Transparent UART mode, which you can integrate with any processor or PIC microcontroller with a UART interface. The module also supports standalone “hostless” operation for beacon applications.
The optimized power profile of these new devices minimizes current consumption for extended battery life, in compact form factors as small as 4 × 4 mm for the RF ICs and 15 × 12 mm for the module. The module options include RF regulatory certifications, or noncertified (unshielded/antenna-less) for smaller and more remote antenna designs that will undergo end-product emission certifications.
The BM70 Bluetooth Low Energy PICtail/PICtail Plus daughter board enables code development via USB interface to a PC. Or you can connect to Microchip’s existing microcontroller development boards, such as the Explorer 16, PIC18 Explorer and PIC32 I/O Expansion Board. The BM-70-PICTAIL costs $89.99.
The IS1870 Bluetooth LE RF IC (6 × 6 mm, 48-pin QFN package) costs $1.79 in 1,000-unit quantities. The IS1871 (4 × 4 mm, 32-pin QFN package) costs $1.76 in 1,000-unit quantities. The 30-pin BM70 Bluetooth LE modules are available with or without built-in PCB antennas, starting at $4.99 each in 1,000-unit quantities.

Linx Technologies recently introduced new pre-certified remote control and sensor transceiver modules. Built on the Hummingbird platform, the HumRC Series transceiver is a frequency hopping spread spectrum (FHSS) transceiver designed for reliable bidirectional remote control and sensor applications. Available in 900 MHz, the HumRC outputs up to 10 dBm, which results in a line-of-sight range of up to 1 mile.
The HumRC Series module is a completely integrated RF transceiver and processor designed for bidirectional remote control. It employs a fast-locking FHSS system for noise immunity and higher transmitter output power as allowed by government regulations.
The remote control transceiver has eight status lines that can be individually configured as inputs to register button presses or as outputs to drive application circuitry. A selectable acknowledgement indicates that the transmission was successfully received. Primary settings are hardware-selectable, which eliminates the need for an external microcontroller or other digital interface.
The transceiver also has two analog-to-digital (ADC) inputs for sensors or circuits that output an analog voltage. The module can automatically respond to a command with these values, so a sensor node does not need an additional microprocessor.
To aid rapid development, the HumRC Series low-cost RF modules are available as part of a newly conceived type of Master Development System. This development kit is intended to assist in the rapid evaluation and integration of the HumRC Series data transceiver modules. It features several preassembled evaluation boards that include everything needed to quickly test the operation of the transceiver modules.

Dialog Semiconductor recently announced that it is collaborating with Bosch Sensortec to develop a low-power smart sensor platform for Internet of Things (IoT) devices. The 12-DOF smart sensor reference platform is intended for gesture recognition in wearable computing devices and immersive gaming, including augmented reality and 3-D indoor mapping and navigation.
The platform comprises Dialog’s DA14580 Bluetooth Smart SoC with three low-power Bosch Sensortecsensors: the BMM150 (for three-axis geo-magnetic field measurement), the BME280 (pressure, humidity, and temperature sensor), and the siz-axis BMI160 (a combination of a three-axis accelerometer and three-axis gyroscope in one chip). The resulting 14 × 14 mm2 unit draws less than 500 µA from a 3-V coin cell when updating and transferring all 12 × 16 bits of data wirelessly to a smartphone.
The 2.5 × 2.5 × 0.5 mm DA14580 SmartBond SoC integrates a Bluetooth Smart radio with an ARM Cortex-M0 application processor and intelligent power management. It more than doubles the battery life of an application-enabled smartphone accessory, wearable device, or computer peripheral in comparison with other solutions. The DA14580 includes a variety of analog and digital interfaces and features less than 15 mW power consumption in active mode and 600-nA standby current.
Bosch Sensortec’s BMI160 six-axis Inertial Measurement Unit (IMU) integrates a 16 bit, three-axis, low-g accelerometer and an ultra-low power three-axis gyroscope within a single package. When the accelerometer and gyroscope are in full operation mode, the typical current consumption is 950 µA.
The BMM150 integrates a compact three-axis geo-magnetic field sensor using Bosch Sensortec’s high performance FlipCore technology. The BME280 Integrated Environmental Unit combines sensors for barometric pressure, humidity, and temperature measurement. Its altitude measurement function is a key requirement in applications such as indoor navigation with floor tracking.

Some people like to remotely start their cars when it’s cold outside. Dan Beadle took this idea one step further by Internet-enabling his mountainside retreat’s hydronics system. The innovative design enables him to warm the house well in advance of his arrival.
Serving up the current temperature involves several computers, a Wi-Fi access point, and a DPAC Airborne module.
In “Wireless Water Heater” (Circuit Cellar 163), Beadle writes:
My mountain home, where I have vacationed for years, is well insulated, making it a snap for the heater system to keep warm. I have a small, efficient heater; however, it takes forever to warm the house from a 50°F standby to a livable 68°F. Typically, I arrive late and shiver in my jacket for three or four hours until the house warms up—and that does not warm the entire house, just the portion needed to get through the night.
I had been thinking for a while about Internet-enabling the system. The idea was to turn on the heater before we start up the mountain. I have DSL at the house with a fixed IP. So, it seemed like it would be a simple task to enable a thermostat. I considered using an X10 thermostat, but, after a few of our X10-enabled lights found a mind of their own, I decided that I wanted better reliability. My next thought was to use simple copper to do the hook-up. I started planning a cable from my office/DSL entry up to the logical thermostat location. Then I procrastinated. I could not bring myself to run the wires along the surface of my redwood paneling. (And it was not at all feasible to remove the paneling.) Wireless makes the problem a lot simpler: there are no wires to run, and the applications processor and digital I/O on the module make the hardware design trivial.
