NOTE1: Android phone only can use SPP to communicate with the module, and IOS phone only can use BLE.

This is bluetooth-compatible debug module with on-board JDY-34 module, USB port and CH340 USB to TTL chip.

You can use your PC and this module to debug JDY-30, JDY-31, JDY-33, JDY-34, HC-06 bluetooth-compatible module.

The module is fully qualified Bluetooth-Compatible V3.0 SPP + V4.2 BLE with complete 2.4GHz radio transceiver and baseband. Your android or IOS phone can communicate with it.

About Force AT switch onboard: when the module is connected with other module, you can push the switch to the Force AT side to enter AT command mode, so you can send some command to control.

Product Features:

– Protocol: Bluetooth-Compatible v3.0 SPP + v4.2 BLE

– Compatibility: can communicate with Android phone, IOS phone, .

– Operating voltage: 4.75V – 5.3V (Onboard 3.3v LDO Regulator)

– Operating current: about 1mA when unpaired, paired 10mA

– Logic Interface Type: UART TTL serial port

– Serial port baud rate: 9600 (default), can be modified to other values by AT command.

– UART communication format: 8N1 (default).

– Effective Distance: Maximum 20 meters in open area

– After pairing, it can be used as a full-duplex serial port, without having to know any Bluetooth-Compatible protocol, but only supports 8 data bits, 1 stop bit, no parity bit communication format, which is the most commonly used communication format. It does not support other formats.

– When not establish a Bluetooth connection, you can set the baud rate, name, passkey via AT commands, parameter settings will be saved at power-down. After Bluetooth connection, it will automatically switch to transparent mode.

– When bluetooth is connected, you can push the onboard switch to the “Force AT” side to make it to be AT mode. Then you can send some AT command.

– Module mode:

–AT+BTMODE0: SPP Multi-slave and BLE slave.

–AT+BTMODE1: default value. SPP slave and master mode, or BLE slave mode.

–AT+BTMODE2: SPP Multi-mater mode without BLE function..

–AT+BTMODE3: SPP slave and master mode without BLE function.

– The default password: NULL and if you send AT command to turn on the password switch, the default is 1234.
