FAQ
QUESTION / ANSWER
- 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.
- How much data can serial port write at one time? No byte limit
- 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
- 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.
- How to get into deep sleep? Recommended power-off mode
- 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.
- 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.
