BT600 series Bluetooth single mode module uses Nordic nRF51822 Bluetooth Low Energy (BLE) chip. Three
antenna options are offered:
BT600I with a chip antenna on module, line of sight range is 30 meters or 90 feet.
BT600E, an external antenna is required. Line of sight range is 50 meters or 150 feet when used with
recommended antenna.
EV-BT600. Development board for BT600 modules. A PC or a host processor can communicate with
BT600 through an UART port. All IO pins are available at connectors.
A host processor can set BT600 to command and data mode by setting an I/O pin to high and low, respectively.
When using with a PC, a jumper is used to set the BT600 IO pin. When in data mode, the host processor
communicates with a smartphone, a computer, or other electronic equipment through this BT module.
1.1. Standalone Mode
BT600 can operate in standalone mode – without a host processor. A 32 bit ARM Cortex™ M0 processor with
128 KB of flash memories are built-in. Development tools are available from Nordic and other 3
rd
parties.
BT600 dimensions and pin assignments are the same as some modules from other manufacturers.
Programming tools are commercially available to reprogram module for standalone operation.
