Concurrent operation of Central and Peripheral mode


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.

Hi Thieny,

Hi Thieny,

Thanks for your question online and for your interest in our TINY module solution.

The DA14531 supports up to 3 BLE connections. Please see section from the UM-B-119: DA14585-DA14531 SW Platform Reference and search for the CFG_MAX_CONNECTIONS.

With regards to the CodeLess, this AT command is not supported but let me ask this internally just to make  sure.

Thanks, PM_Dialog
