Seeed BLE Shield (113030013)
讓 Arduino 透過 UART 轉 BT 4.0 通訊
This Seeed BLE Shield utilizes an HM-11 module to provide your Arduino/Seeeduino with serial BLE function. It only takes two pins of the micro controller to communicate your device with this shield. With support for a BLE ComAssistant APK, this BLE Shield can talk to your mobile phone more easily without pairing. You can use it in many conditions, like robot controls or remote control equipment ,etc. We prepared an easy and convenient command set for this shield so that you can use neat and concise code to run the function.
Features:
- Arduino/Seeeduino compatible
- UART serial port of HM-11 on the Shield can be connected to Arduino by jumpers
- With two Grove connectors, making it easy to connect I2C and digital IO Grove modules to Arduino
- AT commands support

Please visit our wiki page for more info about this product. It will be appreciated if you can help us improve the documents, add more demo code or tutorials. For technical support, please post your questions to ourforum.
- HM-11：The basic module is HM-11, more information you can refer to this wiki of HM-11.
- Signal lamp：Lamp will blink if no one connect BLE, but the lamp would keep lighting after BLE has been connected.
- Grove connectors：There are two Grove connectors onto the BLE shield, you can plug Grove products onto the board conveniently.
- Hard or Softserial port：You can choose two of seven digital pins as the communication channel. Just plug the jumpers into the headers. There are two mistakes on the silkscreen, please kindly regard "WIFI_TX" and "WIFI_RX" as "BLE_TX" and "BLE_RX".
- Reserved pinouts from HM-11：There are some reserved pinouts from HM-11 module, such as CTS1, RTS1 and PIO2, etc.
- Reset button：Press the reset button if you need to reset the BLE Shield. However, this reset button does not affect the state of the main board(such as Arduino Uno) if BLE Shield is plugged onto the main board.
