Hi there,

i am running the BlueNRG with multiple services, such as a proximity service, a performance test service and an application service.

The proximity service has 2 characteristics,
the PerformanceTestService 3 and the AplicationService 13, where
the last characteristic (message) is of type string with a variable size.

The ApplicationService once run alone with the maximum string size.
After adding another service, the BlueNRG responded with BLE_OUT_OF_MEMORY.
I fixed this by reducing the maximum char value size of my ApplicationService's message characteristic to 128, but soon after adding the next service, the problem appeared again.

I would like to know:
Is there a GATT limitation on the board or a maximum GATT stacksize ?

I have read the documentation, however I may have overread it.

Thank you for your answers :)
