GENERAL INFORMATION
DevCircuits’ DC-BLE-1 product will transmit a packet of data approximately every 9 seconds in the 2.4 GHz radio frequency band.
PRODUCT PROGRAMMING
The DC-BLE-1 has no programmable parameters. Future features may be enabled/disabled by resistors R1 through R3 located on the component side of the printed circuit assembly.
THEORY OF OPERATION
The DC-BLE-1 is comprised of a printed circuit assembly, several discrete components, a microcontroller, and a coin cell battery holder. It is powered by a 3V button cell CR-1025 battery. The PCB accepts power through a soldered Keystone battery holder located on one side of the device. The supply voltage can be in the range of 3.0 to 3.6 VDC. The main processing unit of DC-BLE-1 is the Nordic Semi nRF52832. It is a microcontroller with a 2.4GHz transceiver. Memory configuration is 192 Kbytes of Flash and 24 Kbytes of RAM. When the device is powered, it will begin to transmit a packet of data approximately every 9 seconds. Only soft device firmware provided by Nordic Semiconductor and firmware written by DevCircuits, LLC and its affiliates can be installed on the DC-BLE-1. The firmware for the DC-BLE-1 is solely controlled by DevCircuits, LLC., and is not distributed to end users. The DC-BLE-1 is housed in a weatherized, PCB/ABS hybrid enclosure and houses a tuned antenna inside.
FCC COMPLIANCE STATEMENT

- this device must accept any interference received, including interference that may cause undesired operation.
CAUTION: The grantee is not responsible for any changes or modifications
not expressly approved by the party responsible for compliance. Such
modifications could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses,
and can radiate radio frequency energy, and if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
