Next-generation low energy modules support Bluetooth 4.2
Two next-generation Bluetooth Low Energy (BLE) modules have an easy-to-use ASCII-style command interface, says Microchip, to make the devices easy to configure and eliminate any complicated code compiling.
The RN4870 and RN4871 support the Bluetooth 4.2 specification and have a Bluetooth stack on-board with a scripting engine to enable standalone operation and eliminate microcontroller use for simple applications. They are designed to complement the company’s low-energy solutions designed for IoT applications.
The devices deliver up to 2.5 times data throughput improvement over previous generation products, based on Bluetooth 4.0. They offer connection security based on Federal Information Processing Standards (FIPS) and can seamlessly transfer serial data over BLE devices. They support different beacon formats such as iBeacon or Eddystone via a single command. With a shield option, both devices are certified to meet worldwide regulatory standards and have package options as small as 6.0 x 8.0mm.
Each module pairs with any of the company’s low-power microcontrollers or any microcontroller with a UART interface.
The RN4870-V/RM118, which is shielded with an onboard antenna, is available now for sampling and volume production in a 12 x 22mm module. The RN4870U-V/RM118, which is unshielded with an external antenna, is available now for sampling and volume production in a 12 x 15mm module.
The RN4871-V/RM118, which is shielded with an on-board antenna, is available now for sampling in a 9.0 x 11.5mm module. The RN4871U-V/RM118, which is unshielded with an external antenna, is available now for sampling in a 6.0 x 8.0mm module.
The company also offers the RN4870 Bluetooth 4.2 Low-Energy PICtail/PICtail Plus Daughterboard with a sensor board (RN-4870-SNSR). Several existing interfaces will be supported by the RN4870 and RN4871 including the PIC18 Explorer Board (DM183032); the Explorer 16 Board (DM240001/2); and the PIC32 Expansion Board (DM320002).
