Send and receive interrupt lines from nBLE51822 to any MCU

[san27deep]

I have not gone into much details of 51822. while interfacing BLE to any MCU, Is it possible to add interrupt lines from BLE module to MCU to receive interrupts in MCU. Like, if we added one RX INTR line from BLE to MCU and BLE module receives some data, then it will trigger some interrupt to MCU that data is received, vice versa for send INTR.

Is it possible to modify BLE firmware to add such a requirements?

Sure you can use GPIO lines as signalling to any external MCU of events according to your specification, should be pretty straight forward FW development task.
