Summary
This update brings WiFi visibility to KALLO through a new Wi-Fi scan task and daily Wi-Fi blind scan, adds LTE and 5G NR cell identity reporting across all cellular metrics, introduces the option for continuous ping testing, and enables 2G/GSM testing on GSM modem-equipped units. Alongside this, substantial improvements to result queuing, storage management and upload handling ensure collected data is never lost, and a few throughput, voice and log rotation bugs have been corrected.
