    Hi Ujwal,

    Can you check on the heap consumption? Each connection requires quite a bit of memory and you might have run out depending on your setup.

    Please see the Debugging chapter of the Software Developer's Guide: dev.ti.com/.../

    If this is the case, you can either use ble 4.2 (blestack) multirole project which is set up to use the cache memory as extra RAM. This can also be enabled for the ble5_simple_central project, but it's not there by default. Please find the description in the software developer's guide.

    Best regards,
    Aslak
