HC-05蓝牙RSSI不适用于Arduino [英] HC-05 bluetooth RSSI not working with Arduino

问题描述

我无法让HC-05蓝牙模块输出RSSI值.我依次发出以下命令:

I cannot get my HC-05 bluetooth modules to output RSSI values. I issue it the following commands in series:

AT+INIT
  -> *OK*
AT+INQM=1,9,48
  -> *OK*
AT+INQ
  -> *No response, it starts flashing rapidly, indicating AT mode is no longer active*

在执行INQ命令后，它开始的模块快速闪烁.我认为这意味着它已经退出了AT命令模式，并且对INQ请求没有任何响应.我必须在INQM之前发出INIT命令吗?否则会返回错误(16).

After the INQ command, the module it starts flashing rapidly. I think this means it has exited AT command mode, and I get not response on the INQ request. I have to issue the INIT command before the INQM? as otherwise it gives back an error(16).

我什至尝试购买其他型号的HC-05，但这无济于事.

I have even tried purchasing a different make of the HC-05, but that did not help.

为什么会这样，我该如何解决?

Why is this happening, and how can I solve it?

EDIT :仅需更多信息，我还有AT + VERSION吗?命令在那里，并且对版本的响应就很好.唯一不起作用的是AT + INQ ...这是我启动串行监视器时的输出:

EDIT: Just for some more info, I also have an AT+VERSION? command in there, and that responds just fine with the version. The only thing that does not work is the AT+INQ... Here is the output when I start up my serial monitor:

bt2bt HC module - version a
BtSetCmdMode 1
BtReset
Set as Master
OK

+VERSION:2.0-20100601
OK

OK


OK

UPDATE :开始闪烁后，我仍然可以与该模块通信: "AT + STATE" -> +状态:正在查询 但是如何从模块中获取对INQ命令的响应?

UPDATE: I can still talk to the module after it starts flashing: "AT+STATE" -> +STATE:INQUIRING But how can I get the responses to the INQ command out of the module?

推荐答案

尝试

at+inq\r\n

根据此，第17页

HC-05的流程应为:

The process for HC-05 should be:

at+init\r\n ---- Initialize the SPP profile lib( can’t repeat initialization) 
     -> OK 

at+iac=9e8b33\r\n ----Inquire Bluetooth device has an access code 
     -> OK 

at+class=0\r\n ----Inquire the Bluetooth device type 

at+inqm=1,9,48\r\n 

At+inq\r\n ----inquire the Bluetooth device around
