Supports for Bluetooth 3.0+EDR Specification Powered via Arduino USB connection or Arduino external power supply.Ĭommunicates with Arduino via UART-TTL and digital input/output. FeaturesĬontrolled by AT Command (3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands)Ĭompatible with Arduino Uno, Arduino Leonardo, Arduino Mega The new AT command for bluetooth also has been upgraded in the wiki.Īnd if you want to update your old version sim808 shield, we also provide tutorial and component / antenna that you need. We improve our versions by upgrading bluetooth firmware. Now we has developed a new function for this board, it's become a GSM/GPS/Bluetooth three-in-one function module now. In quick settings: To find the quick setting for Bluetooth, select the Network, Sound, or Battery icons ( ) next to the time and date on the right side of your taskbar. This module can do just about everything, like make and receive voice calls using a headset or an external 32Ω speaker+electret microphone, send and receive SMS messages or send and receive GPRS data (TCP/IP, HTTP, etc.). Here's how: In Settings: Select Start > Settings > Bluetooth & devices, and then turn on Bluetooth. Also breakouts for external 32Ω speaker and electret mic if you don't want to use a headphone It is based on the latest GSM/GPS module SIM808 from SIMCOM, supports GSM/GPRS Quad-Band network and combines GPS technology for satellite navigation.It has high GPS receive sensitivity with 22 tracking and 66 acquisition receiver channels.It has tandard 4-pole TRRS headphone jack so that you can use any 'Android' or 'iPhone'-compatible headset with mic. Keep reading from Arduino Serial Monitor and send to HC-05Īrduino Bluetooth Interface with Mindwave.SIM808 GPRS/GSM+GPS Shield is a GSM and GPS two-in-one function module. Keep reading from HC-05 and send to Arduino Serial Monitor SendBlueToothCommand("AT+INQM=1,9,48\r\n") // Sets inquiry mode SendBlueToothCommand("AT+CLASS=0\r\n") // Sets the type of bluetooth device, 0 is standand SendBlueToothCommand("AT+IAC=9E8B33\r\n") // Sets code to GIAC type (General inquiry) SendBlueToothCommand("AT+BIND=2068,9d,4c1174\r\n") // Link with the mindwave.

I would really appreciate it if someone could have a look at one of the sketches I have downloaded and modified to see if they can spot the problem.īelow is the code to modify the Bluetooth shields settings. This results in some seemingly random numbers (generated in the ReadOneByte() function) being sent to the serial monitor although the link LED on the bluetooth shield does not come on to indicate a connection between the two devices. ![]() I have also tried changing the baud rates as various sites on the web report success with different baud rates but none that I have tried work.The closest I have come is when I use the sketch below and start the bluetooth shield in inquiry mode and then switch it to AT command mode. But nothing I have tried has connected the mindwave device to the shield. I can connect the bluetooth shield to my android phone and I can modify the settings of the bluetooth shield using AT commands. Unfortunately, I can not find any documentation on the Bluetooth shield that may have helped. I have read and tried to apply all the different instructions out there on the web (most of which use the Bluesmirf device), all to no avail. The problem is that I can not for the life of me get the mindwave to connect to the bluetooth shield. For several days now I have been trying to connect my arduino to the Neurosky Mindwave mobile device using a Bluetooth shield (Duinofun Bluetoothshield v1.3 bought from DX.com).
