BlueNRG1 上的 BlueNRG_Stack_Initialization 错误 0x48

Question

I have been having struggles while programming the Bluenrg1, more specifically when trying to start the BLE mode on it.

The method BlueNRG_Stack_Initialization is returning 0x48 which refers to BLE_STATUS_OUT_OF_MEMORY . All this happened with the DK version 3.2.2 for the bluenrg1 and bluenrg2.

I could obtain the 3.2.1 version of the DK and it works well. After some research I found the value that cause the error, I'll post the solution for my own question to help anybody having the same problem.

Answer 1

The problem appears because of a change on the Bluenrg1_stack.h header located on the folder ../Bluetooth_LE/inc/ of the DK 3.2.2 ->

Change FIXED_BUFFER_SIZE_BYTES from 6480 (DK 3.2.1) to 6536 (DK 3.2.2)
Change VARIABLE_BUFFER_SIZE_PER_LINK_BYTES from 336 (DK 3.2.1) to 344 (DK 3.2.2)

The VARIABLE_BUFFER_SIZE_PER_LINK_BYTES creates the error because it requires more memory allocation than the one created on the beacon configuration.

Just rever the value to the one on the DK 3.2.1 and it will run without an error.
