Bluetooth and Wi-Fi for EC200U-CN Module

[Navya_A]

Hello,
I have a EC200U which has a firmware version of EC200UCNAAR02A10M08 does it support BLE and Wi-Fi? If yes, is there any command manual or a guide that I can follow?

Hi,

If WIFI and Bluetooth functions are not selected when purchasing this module, they are not supported by default. Information about this has been previously provided in the link below.

EC200U - Wifi - Blutooth

Hi, I have an a doubt about EC200U modem. Is there inbuilt Wi-Fi and Bluetooth feature in inside of this modem. If there is available in this modem. Please send the application note for Wi-Fi and Bluetooth features. Thanks,

Hi @Emre_Karabek ,
Thank you for the reply, seems like the supplier has enabled BLE. The document in the conversation also helps. I just have one more doubt the document says:

AT+QBTPWR=(enable)
(enable) Integer type. Turn on or off BT. Range: 0–127 (in ORed).

But then when I query AT+QBTPWR=?
it gives : +QBTPWR: (0-5)

Is it software or hardware constraint?

Hi @Navya_A,

It doesn’t support Wi-Fi, but it does support BLE.

AT+QBTPWR is used to select BLE profiles.

The parameter is a bit mask (0–127). Each bit represents a different protocol:

1 → BLE GATT Server
2 → BLE GATT Client
4 → SPP
8 → HFP
16 → A2DP + AVRCP
32 → A2DP Source + AVRCP Destination (not yet supported)
64 → HFP AG

Since your module outputs AT+QBTPWR=? (0–5):

Only BLE GATT Server, BLE GATT Client, and SPP are supported.
Other profiles like HFP and A2DP are not available in this version due to hardware limitations, I believe.
Therefore, I suspect the restriction is related to the hardware version and hardware support, not the software.
