Bluetooth Modul HC-06

Bluetooth Modul als RS232/TTL Verlängerung.

Mit diesem Bluetooth Modul kann eine serielle Schnittstelle für RS232/TTL aufgebaut werden. Dabei dient das Modul als Tranceiver auf einem Steuerungsboard und auf der Hostseite kann ein PC oder ein PDA/Handheld als Sender verwendet werden. Das Modul übernimmt dabei selbstständig die Funkkommunikation und stellt sich dem Steuerungsboard als eine einfache RS232 Schnittstelle auf TTL-Basis dar. Das Steuerungsboard wird dabei von der Software für das Funkprotokoll entlastet. Die einfache Nutzung der seriellen Schnittstelle reicht.

Es ist so möglich, eine Kommunikation zu einem 3D-Drucker oder einer Fräse mir GRBL-Controller ohne USB-Kabel zu realisieren.

Das Modul ist kompatibel zu den Modulen HC-06. Anleitungen sind im Internet zu finden, wenn bei Google nach HC-06 oder JY-MCU gesucht wird.

1, the core module using HC - 06 from module, which leads to the interface includes VCC, GND, TXD, RXD, reserved LED state output pin, MCU can state whether the bluetooth is connected through the foot, from the machine KEY pin is invalid

2, the led indicator bluetooth connection status, twinkle said there was no bluetooth connectivity, Chang Liang said bluetooth connection and open the port

3, 3.3 V ", as the input voltage 3.6 ~ 6 V, current about 30 ma when the unpaired, matching after about 10 ma, no more than 7 V input voltage!

4, interface level 3.3 V, can be connected directly to a variety of single chip microcomputer (51, AVR, PIC, ARM, MSP430, etc.), 5 V microcontroller can also be connected directly, without MAX232 couldn't through MAX232.

5, clearing the effective distance of 10 meters, more than 10 meters is possible, but not to this distance connection quality

After 6, pairing when full duplex serial port to use, do not need to know any bluetooth protocol, but supports only one in the eight data bits, stop bits, no parity checking the communication format, which is the most commonly used communication format, does not support other formats.

7, when the bluetooth connection has not been established support by pairing the AT command set baud rate, name, password, set the parameters of the power save. After the bluetooth connection automatically switch to passthrough mode

8, small size (3.57 cm * 1.52 cm), SMT production factory, ensure the quality of the patch. And set transparent heat shrinkable tube, dustproof and beautiful, and there are certain antistatic ability.

9, the link from the machine, from the function and all kinds of computer with bluetooth function, bluetooth host, with most of bluetooth mobile phone, PDA, PSP, such as intelligent terminal matching, between the machine can not match.

The small common sense (very important) :

TXD: sender, usually expressed as the sender, normal communication RXD must answer another equipment.

RXD: receiving end, usually expressed as the receiver, the normal communication TXD must answer another equipment.

When normal communication itself TXD pick up equipment RXD forever!

Since collect spontaneous: normal communication TXD RXD connect other devices, so if you want to receive their send data as the name implies, is receiving themselves to send data, is directly connected to the RXD TXD itself, that is, used to test whether the sending and receiving of normal itself, is the most simple test method is the fastest, when problems arise first do this test to determine whether the product failure. Also known as the loopback test.
