how to receive notification data at STM32WB p2p Router from STM32WB BLE p2p Server?

[Kedar.cognota]

I am able transmit 240 bytes of data from STM32WB BLE p2p server. This data want to receive on STM32WB BLE p2p router code.

I am getting ACI_GATT_NOTIFICATION_VSEVT_CODE case executed but I see pr->Attribute_Value_Length is 20. I am transmitting 240 bytes but I receive 20.

If I transmit data less than 20 then at receive side correct information and correct data length is received.

Please guide me how can a receive all 240 bytes correctly and repeatedly.

Thank you in advance!
