I have developed an Android app using Thunkable that interfaces with a built-in BLE printer. While I can establish a connection and print, I'm encountering issues with certain ESC/POS commands. I require assistance to resolve these issues. Specific Command Issues: - Line Feed - Form Feed - Font Changes - Barcode Printing: Issues with barcode printing ESC/POS commands not generating correct output. The primary problem I'm facing is that some commands are not being recognized by the printer. This discrepancy is impacting the output and overall functionality of the app. The commands are being sent over Bluetooth connection to the printer. Ideal Skills and Experience: - Extensive knowledge of ESC/POS commands - Experience with Bluetooth connection troubleshooting - Proficiency in app development, specifically with Thunkable - Previous experience with BLE printers would be a significant advantage
