What makes it special?

Jdy-34 transparent transmission module is based on Bluetooth ble4. It has 2 protocol + 3.0 standard, supports ble and spp working at the same time, and spp supporting multi connection and spp master-slave working at the same time.

It does not need to be separately configured as a host or slave function. In multi-connection mode, spp supports 7 master-slave computers (Android or computers) to connect with 1 IOS mobile phone. BLE also supports Android or IOS connection, and in host mode, it supports the connection with the market. All spp slave computers are connected for communication, including jdy-30, jdy-31, jdy-32, jdy-33, printer, etc.

The communication interface is standard UART, which can configure working mode, baud rate, ble Bluetooth UUID, pairing password and other parameters through at command. The main advantage is high-speed communication. Spp supports 40kbyte / s data transmission and multi connection function after connecting with mobile phone or computer.

FAQ

QUESTION / ANSWER

  1. How to disconnect Bluetooth from MCU in connection state? In the connection state, pull down the PWRC pin, and the serial port sends AT+DISC to disconnect.
  2. How much data can serial port write at one time? No byte limit
  3. What is the fastest communication rate? The actual test speed of SPP and computer or mobile phone is 40K Byte/s The actual test communication speed of BLE and IOS mobile phones is 14K Byte/s
  4. There is no instruction to configure SPP master in the manual. SPP is master and slave simultaneous work 9 and do not need to be configured separately.
  5. How to get into deep sleep? Recommended power-off mode
  6. Why can't it multi-connected by default? The default is AT+BTMOED1 mode,which is an alternative single connected mode. For multi-connection, please configure AT+BTMODE0 mode.
  7. Is thp serial port baud rate still the default baud rale when SPP'shigh-speed 40K byte/S is verified? Please use IM or 750000 or 600000 baud rate setting.
