Scan device with Bluetooth Bee V2.0

Hello,

I’m software embedded developper in french telecom society.

I use bluetooth bee V2.0 on my system.
seeedstudio.com/wiki/Bluetooth_Bee_v2.0

But I have a problem in master mode.

When I want to use a command AT+SCAN?, I haven’t response from module…
I respect the process of wiki page, but I haven’t success just for this command… In any case, the command is not OK.

Can you help me please ? someone has met this problem ?

Thanks in advance for your answer !

Regards,

Julien
