MC60E- Maximum number of devices that the client can connect to

IoT Modules GSM Module
1

Greetings everyone,

I’ve recently begun working with the MC60E module to establish a client-side connection to a BLE sensor. I have a question: how many servers can connect to a single MC60E in client mode? According to the AT command datasheet, the connection ID falls within the range of 0 to 255. Does this imply that the module can handle simultaneous connections to 256 devices?

Thank you for your assistance.

I just tried to connect to two BLE devices. It works fine, but when I tried to connect to another one (the third device), the MC60E returned the error number 8323, meaning the GATT client connect failed. Does that mean the MC60E can connect to just two devices simultaneously? As I know in BT4.0 there is no limitation on the number of connections, so why I am limited to two connections?
