Hi there,

Unlikely is actually an ATT error, which maps to 14 (0x0E), you can see this in ble_gatt.h:

#define BLE_GATT_STATUS_ATTERR_UNLIKELY_ERROR 0x010E /**< ATT Error: Very unlikely error. */

Please note that the 0x01 that preceeds the 0x0E is only internal to the stack.

Are you running an ATT client or server in the nRF51?

If using a server on the chip, are you using authorization at all, where you can override the error code sent back to the client? (i.e. are you calling sd_ble_gatts_rw_authorize_reply() ) ?
