I refer to figure 1 to operate 9.04 and BT-410.
When I reconnect BT-410 and enter "at+btinq", the error in figure 2 is returned.
Could you tell me where I went wrong, or do you have a more detailed description of the match?
Please make sure that you are entering BTINQ command to the Master module.
From eManual it is described as below,
"7. Searching for peripheral devices only works when the BT-410 is in MASTER mode. As seen in the image below, input “AT+BTINQ” and press enter to display devices nearby with the device class 0x1F00(SPP)."
