NRF_ERROR_INVALID_ADDR with sd_ble_uuid_decode

[granaghan]

I'm calling sd_ble_uuid_decode with the following parameters on a PCA10040 board:

sd_ble_uuid_decode(16, 0x2000F7CC, 0x2000F7DC)

ram base = 0x20003150

vs_uuid_count = 1

SDK: 14.0.0 Softdevice: 5.0/S132

As far as I can tell, all of the above should work properly. What specifically causes NRF_ERROR_INVALID_ADDR with this function? I'm at a loss on where to look at this point.

The documentation says:

 * @retval ::NRF_ERROR_INVALID_ADDR Invalid pointer supplied.

Could you include some code showing how you set up the pointers and call the function?

[granaghan]

They're both on the stack. I saw the documentation, but it's not clear on what makes a pointer invalid. I assume location, but what about other issues such as alignment?

ble_uuid128_t uuid128_le = getUuid(); 
ble_uuid_t nrf_uuid = {};
uint32_t result = sd_ble_uuid_decode(16, uuid128_le.uuid128, &nrf_uuid);

I don't think alignment should be a problem. I'm not sure why you get that error. You are sure sd_ble_uuid_decode() returns 0x00000010? Would it be possible to share your complete project with me? So I can try to reproduce?
