103 Remove Sesame (Delete Device)

The phone sends a delete command and device name, sesame5 responds that the command is successful, and ssm_touch actively pushes the Sesame list to the phone. (For details on the Sesame list, see 102_pub_ssm_key.)

Android Example

  override fun removeSesame(tag: String, result: CHResult<CHEmpty>) {
      if (checkBle(result)) return
      if (ssm2KeysMap.get(tag)!!.get(0).toInt() == 0x04) {// ss4
          val noDashUUID = tag.replace("-", "")
          val b64k = noDashUUID.hexStringToByteArray().base64Encode().replace("=", "")
          val ssmIRData = b64k.toByteArray()
          sendCommand(SesameOS3Payload(SesameItemCode.REMOVE_SESAME.value, ssmIRData)) { ssm2ResponsePayload ->
              result.invoke(Result.success(CHResultState.CHResultStateBLE(CHEmpty())))
          }
      } else {//ss5
          val noDashUUID = tag.replace("-", "")
          sendCommand(SesameOS3Payload(SesameItemCode.REMOVE_SESAME.value, noDashUUID.hexStringToByteArray())) { ssm2ResponsePayload ->
              result.invoke(Result.success(CHResultState.CHResultStateBLE(CHEmpty())))
          }
      }
  }

iOS Example

    func removeSesame(tag: String, result: @escaping CHResult<CHEmpty>) {
        if (self.checkBle(result)) { return }
        L.d("[hub3][removeSesame]",tag)
        let noDashUUID = tag.replacingOccurrences(of: "-", with: "", options: [], range: nil)
        sendCommand(.init(.removeSesame,noDashUUID.hexStringtoData())) { (response) in
            result(.success(CHResultStateNetworks(input: CHEmpty())))
        }
    }
