Take a look at the S130 SoftDevice.

Hello, I need to develop BLE device on nRF51822 that can:

act as BLE Central device for reading data from BLE sensors. 2 act as BLE periferal device, so it can be configured from android smartphone. What there is the easiest way to solve this?

S120 is a Central softdevice, capable of keeping a connection to up to 8 Peripherals while scanning. See the S120 SoftDevice specification for details.

There is no built-in meshing capabilities in BLE, and the S120 can not be both a Central and a Peripheral simultaneously, so it's not easy to use it for mesh topologies. For such use cases, it's probably better to either build on ANT, or build something custom directly on the RADIO peripheral of the nRF51822. Beware that this is not trivial however, and would require significant development effort. You may have use in taking a look at this question.
