One of the key challenges we are currently facing is ensuring seamless communication between devices using Wi-Fi Direct and Bluetooth, as these technologies often have compatibility issues across different operating systems and device models. Maintaining connection stability and reliable data transfer in offline mode is proving to be complex, requiring constant testing and fine-tuning. We are also working on creating a user-friendly interface for device discovery and connection, which is challenging due to the technical intricacies of peer-to-peer networking. Integrating geo-tagged messaging has been particularly demanding, as it requires precise handling of location services and offline storage. Additionally, balancing privacy and performance remains a significant hurdle, as we aim to ensure secure, direct communication without compromising speed or usability.
