請(qǐng)問(wèn)CH579做藍(lán)牙主機(jī)時(shí)，怎么讀取從機(jī)發(fā)送的notify呢？
主機(jī)無(wú)法開(kāi)啟從機(jī)notify，會(huì)提示"Write Error: 1"，請(qǐng)問(wèn)應(yīng)該如何解決呢？
attWriteReq_t?req;
?????????
req.cmd?=?0;
req.sig?=?0;
req.handle?=?GATT_CLIENT_CHAR_CFG_UUID;
req.len?=?2;
?
req.pValue?=?GATT_bm_alloc(centralConnHandle,ATT_WRITE_REQ,req.len,NULL,0);
if?(?req.pValue?!=?NULL?)
{
??req.pValue[0]?=?1;
??req.pValue[1]?=?0;??
?????
??if(?GATT_WriteCharValue(centralConnHandle,&req,centralTaskId)?==?SUCCESS?)
??{?????
????????printf("\r\nenable?notify\r\n");
??}
??else
??{
????GATT_bm_free((gattMsg_t?*)&req,?ATT_WRITE_REQ);
}
