Why 250 ms interval between subsequent reads?

[HeS]

I observe strange behavior while reading value for long characteristics.

I have characteristic 100 bytes long (read only). In GATT client I must read value with subsequent reads (sd_ble_gattc_read with proper offsets). Everything works fine with one exception. Subsequent packets are received at intervals of 250 ms. Why? Where is this "magic interval" set? With my characteristic 100 byte long I need spend 1 second to get full value (and keep connection!).

It would be very helpful if you could upload a sniffer trace of the transaction.
