Pipe error 0x92 using nordic 8001 and Android

[Nadgob]

Sometimes I receive pipe error 0x92 when I try to send a message from nordic to Android. What could be the causes for a pipe error 0x92?

I saw this: "Pipe Error Event : Peer device has sent an error on an pipe operation on the remote characteristic" but I don't really understand what could cause this. The problem is on the phone or on the bluetooth side?

Thank you!

The Pipe Errors are explained in the appendix of the nRF8001 product specifications. See section 28.1 with ACI Status codes. The error 0x92 is ACI_STATUS_ERROR_PEER_ATT_ERROR, which means that the peer sent an Error Response to the nRF8001 being used as a GATT Client, the peer is the GATT Server. This would happen on the RX_REQ Pipe (GATT Client) and on TX_ACK Pipe (GATT Client).

The may be an additional 1 byte error code that provides you more information, see volume 3 Part F Section 3.4.1 , Attribute PDUs, Error handling to get more information on the error code.
