Is it possible to send image files using goTenna Mesh?

File Transfer Capabilities

goTenna Mesh devices support sending and receiving files, including images, through the app. However, file transfer sizes are limited to 10 KB due to the network protocol’s efficiency and memory constraints. When transferring images, it’s essential to compress them before sending to stay within the file size limit.

Image Compression Techniques

To successfully transfer image files, users can employ various image compression techniques through the goTenna Mesh app. The app includes an image resizer that compresses images to 10 KB or less, allowing for transfer. Additionally, users can use third-party image compression tools to reduce the file size before transferring. For example, compressing a 2-megapixel image from a smartphone to 10 KB or less is achievable with the right software and settings.

Sending and Receiving Images

To send images using goTenna Mesh, users must first compress the image to 10 KB or less. Then, they can select the compressed image file within the goTenna app and send it to another goTenna Mesh user. The receiving user can then save the image to their device. It’s worth noting that image resolution and quality may be affected by the compression process, so users should be prepared for some degradation in image quality.
