Concurrent operation of Central and Peripheral mode

Hi,

I am using the DA14531MOD module on an IoT-device and want to connect to BT sensors with the module as master/central and "simultaneously" connect a smartphone to the module which can control the IoT device with the module as slave/peripheral. When the IoT device connects to the sensors to achieve their data, the user should not get a disconnect notification in the app on its smartphone.

Is it possible to set up this configuration with CodeLess? And how can I do this?
How many connections at one time are possible with the DA14531MOD in central role?

Thanks in advance.
Best regards.
