Problem communicating between the EC200UEUAA module and the ELM327 (spp_c and hc05 modules) dongle via classic Bluetooth and Quecpython

Hi. I am trying to connect to an ELM327 Bluetooth dongle which is an OBD interpreter using the EC200UEUAA module’s Bluetooth and SPP profile, but when the connection is established, the EC200U module crashes and resets when I run api bt.sppSend(‘ATI\r’). I am using the latest firmware version of this module (V0005) and of course I tested it with version V0004 but the problem still exists. There is no problem in connecting the EC200U to my mobile phone, and the connection is completely establishe…
