BlueNRG-1 Latency

Question asked by res.theodor on Dec 14, 2016

Hi,

Please help me with the following theoretical situation: I have a BlueNRG-1 running HID profile, mostly sleeping. From time to time, an external interrupt occur (GPIO line) and the time interval in which the MCU must handle this interrupt is 150us, when running the handle code only takes 50us.

Is it possible to configure the interrupt priorities in such way that the MCU will handle the interrupt EVERY time ? i.e. is there a way to define a critical section in the code that overcome the BLE low level routines?

Thanks
