Hello, I have a board that uses the EC200A-EUV1 module. While I have no issues with 3G connectivity, I’m experiencing problems with LTE. I would like to change the band, but my firmware version is outdated. My current firmware version is EC200AEUV1HAR02A06M16_01.001.01.001. Could you please send the latest firmware version to fatihunal3@gmail.com?
