Issues with large data transmission via Bluetooth Low Energy using the nRF52840 donglehttps://devzone.nordicsemi.com/f/nordic-q-a/124929/issues-with-large-data-transmission-via-bluetooth-low-energy-using-the-nrf52840-dongleHi, I&#39;m currently facing an issue with my nRF52840 chip acting as the transmitter connected to a BLE broadcasting device. One client uses a voice recorder product that requires us to subscribe to their data via a specific BLE characteristic.
