ACI STATUS ERROR UNKNOWN

[terry]

I am using nRF8001 with EMF32.

inside hal_aci_tl_send function C : 1, 14, inside hal_aci_tl_event_get function E : 3, 132, 128, 130, It is looks like Length == 3 CommandResponseEvent (0x84 == 132) ACI_STATUS_ERROR_UNKNOWN Unknown error (0x80 == 128)

Any suggestion

If you are sending the command(C) 0x14, according to the datasheet of the nRF8001 , that command is OpenRemote pipe that needs a a parameter. I.e. the Length is expected to be 1. However "C : 1, 14 ", means that the remote pipe parameter is missing.

Even if you were printing it as Decimal i.e. 14 == 0x0D, the Command is still incorrect as there are no parameters for the Command. 0x0D is SetLocalData, which has a length longer than 1.

The Command Response Event is also documented in the nRF8001 datasheet. "E : 3, 132, 128, 130" , means an Event length of 3, CommandResponseEvent (0x84 == 132) , Command code of 128 == 0x80, which does not even exist in the datasheet and the status code of 130 == 0x82 which means, 0x82 ACI_STATUS_ERROR_CMD_UNKNOWN Unknown command.

This is very likely that the ACI command sent was not correct or has invalid parameters.

Have you verified your SPI using the Echo Command and Echo Event loopback so that the SPI issues do not get in here and confuse the issue. Look at the ACI transport verification example in the Arduino SDK and the porting note for the nRF8001.

Are you using the EFM32 port on github ? If so please post an issue on the github as well. OR Are you building your own driver for EFM32 ?
