How do I send large size data?



BLE Nano v2 supports Bluetooth 4.2.
Bluetooth 4.2 can transmit more than 20 bytes of data at a time, but it did not work well when I tried it with BLE Nano v2.
GattCharacteristic’s maxLen was set to a value greater than 20 bytes, and the updateCharacteristicValue () argument also set a value greater than 20 bytes, but only 20 bytes were sent at a time.
How should I implement it?



I would also like to know how to resolve this issue, or if OP ever found a solution.
