Uploading state of firmware update to firebase impossible?

[rbovenkampclearict]

I want to upload the state of the firmware update to firebase, but it seems impossible? Or am I missing something? I can see the serial line but nothing is uploaded to firebase.

  if (info.status == fb_esp_fcs_download_status_init) 
  {
    Serial.println("1st if");
    delay(10000);

    std::string statusMessage = std::string("Completed") + std::string(" (") + std::string(info.remoteFileName.c_str()) + std::string(") ") + std::to_string(info.fileSize);
    delay(10000);

    Serial.println(statusMessage.c_str());
    Firebase.RTDB.setString(&fbdo, "/update/download status", statusMessage.c_str());  
  }

It's not possible if you are using the same FirebaseData object i.e., fbdo in this case to send data to RTDB while it was used for downloading data from Firebase Storage.

You should use different FirebaseData objects to do the tasks simultaneously.

Delay should be removed from your download callback function because it blocks other codes to run, and you should not call any function in the callback function to avoid stack overflow.

You should store FCS_DownloadStatusInfo in your global variable and calling Firebase.RTDB.setString with another FirebaseData object in the main loop() based on your global variable status like the following.

FCS_DownloadStatusInfo downloadInfo;

void fcsDownloadCallback(FCS_DownloadStatusInfo info)
{
  downloadInfo.status = info.status;
  downloadInfo.progress = info.progress;
  downloadInfo.errorMsg = info.errorMsg;
  downloadInfo.elapsedTime = info.elapsedTime;
  if (info.status == fb_esp_fcs_upload_status_init)
  {
    downloadInfo.remoteFileName = info.remoteFileName;
    downloadInfo.localFileName = info.localFileName;
    downloadInfo.fileSize = info.fileSize;
  }
}

loop()
{
  if (downloadInfo.status == fb_esp_fcs_upload_status_complete)
  {
    std::string statusMessage = std::string("Completed") + std::string(" (") + std::string(downloadInfo.remoteFileName.c_str()) + std::string(") ") +
                                std::to_string(downloadInfo.fileSize);

    Serial.println(statusMessage.c_str());

    // Local fbdo
    FirebaseData fbdo_local;
    Firebase.RTDB.setString(&fbdo_local, "/update/download status", statusMessage.c_str());
  }

  // Other Filebase code here that calling Firebase.ready() 
}
