Description

The KC-4114 low energy modules are pre-engineered, pre-qualified, and highly tuned surface mount PCB modules that provide fully embedded, ready to use Bluetooth low energy wireless technology. Multi-surface pads provide both bottom pads for high volume reflow soldering and edge pads for low volume hand soldering.

Our kcEnergy embedded firmware provides an easy to use AT style command interface over UART. kcEnergy is capable of storing OEM default settings, and is wirelessly upgradable. kcEnergy also provides remote control capability, where our AT commands can be issued remotely from any other Bluetooth Low Energy or dual mode EDR device using GATT. Custom firmware is available upon request.



Standard Bluetooth Low Energy Profiles

The KC-4114 Low Energy modules comes standard with KcEnergy firmware which includes support for GAP, GATT, FMP, PXP, LLS, Device Information, Battery profiles, and other profiles and services. Here is a description of some of the main ones.

GAP – Generic Access Profile

The Generic Access Profile is a BLE mandatory profile responsible for the device name, appearance and Bluetooth connecting, advertising, and scan responses. It determines device interactions and defines the peripheral or central roles between two devices. It is also where pairing, bonding, and security measures take place.

GATT – Generic Attribute Profile

The Generic Attribute Profile is the profile in which determines how two BLE devices transfer data via the client/server relationship. The server is the device with the service and the client is the device that communicates with the server to complete the service. The GATT governs profiles, services, and characteristics transactions. Its job starts once two devices are connected. Other BLE profiles, besides GAP, are GATT based.

FMP – Find Me Profile

The Find Me Profile is a profile designed for locating another low energy device. An alert signal is activated on one device, while a trigger is set on the other device.

PXP – Proximity Profile

The Proximity Profile is used as an alert system that activates when two connected devices become out of range or beyond a desired distance. This triggers a response for the device, such as locking down, shutting off or perhaps rescanning for devices. It can also be used to detect when devices are closer, such as to trigger a different response like reconnection. It works in a proximity monitor and proximity reporter relationship where the GATT server is the proximity reporter.

LLS – Link Loss Service

The Link Loss Service is responsible for defining the behavior of a device after a link is lost between two devices. This service does not require other GATT –based services or devices.

BAS – Battery Service

The battery service is an internal device service that monitors and exposes the state of the battery within a device.

OTA– Over The Air Update mode

The over the air update mode enables users to update the application software using a wireless server/client connection. This is a different operating mode from the devices normal operating mode. The host device will actually disconnect from the server and then reconnect under the update mode. When the update is complete, the host disconnects and then resets, starting the new device application. Upon updating, the GATT database may change depending on the actions of the update.

Other Bluetooth Low Energy Profiles

KC-4114 is capable of supporting additional Low Energy profiles. Please contact KC Wirefree for customization options.

Interface Pins

AIO Interface Pins [2,3,4]

AIO 0, AIO 1, and AIO 2 are enabled for analog input by default, providing 10 bit samples. Analog pins are 1.8V logic for input mode. Voltage reading accuracy is guaranteed to 10 bits resolution. AIOs can also be used as digital PIOs if need be.

UART Pins [5,6]

The UART is industry standard, and operates at a logic level of VDD. A buffered signal IC is recommended for voltage translations to different UART voltages. UART pins can be re-assigned as PIO pins in firmware if desired. Available settings: 1200 – 2Mbps Baud rates, RTS/CTS flow control is available as a software implementation, None/Odd/Even parity, Stop Bits 1/2, Data Bits 8. Factory default is 115200-8-N-1.

PIO Interface Pins [7,8,9,10,11,12,13,14,15,17]

PIO pins are read and write enabled via kcSerial commands. Inputs can be configured for weak pull-up, weak pull-down, strong pull-up, strong pull-down. Voltage input tolerance and output level is equal to the VDD level. Note Pin 17 (Pio 2) is used to control the EEPROM during startup. Afterwards, it is available for general use.

SPI Pins [9,10,11,12,16]

The SPI pins are only available for firmware loading and test tools. Pin 16 [SPI] (HIGH) enables the SPI bus on pins 9 [CK], 10 [CS], 11 [MO], 12 [MI]. Otherwise, these pins operate as PIO pins.

We highly recommend providing a header or test points for each of these pins for emergency diagnostics access.

Wake Pin [18]

The wake pin will exit all sleep modes. It is the only pin that will wake the device from the deepest sleep mode (Dormant).

VDD Pin [19]

Voltage supply pin accepts voltages between 1.8V - 3.6V. If a voltage regulator is used, it should have a fast response time < 20µs. It is essential that the power rail recover quickly. We recommend Texas Instruments TLV71333PDBVR. If a lithium coin battery is used, a large bypass capacitor (47µF – 100µF) is highly recommended due to increasing battery resistance when depleting. Note, the USB, UART, and PIO pins high outputs will be driven relative to this VDD input voltage level.

GND Pin [20]

System ground.



Current Consumption

Operation Mode Consumption Wake Time Description

Wireless TX/RX < 16mA Wireless operations.

Idle <1 mA Wake time < 1μs All systems are active, without wireless activity.

Deep Sleep < 5μA Wake time < 1ms Wireless radio is still available and UART is only available if baud rate is <2400 bps. Analog outputs are off. Device can wake up with radio, Uart, PIO, or WAKE pin activity.

Hibernate <1.5 μA Wake time < 1ms Wireless radio and most other systems are off, but RAM is still active and firmware still runs. Device can wake up with an internal timed event or WAKE pin.

Dormant <600 nA Only an internal clock is running. Device can wake up with WAKE pin only. The device essentially reboots and loads firmware upon wake up.
