BLE write doesn’t work after requestmtu

[trayvon2017]

1.Select a device from the list using scan() method.
2.Connect to device using the device id received from scanning.
3.On success callback from ble.connect, when device is connected, request MTU size using ble.requestMtu()
4.write data to ble device using ble.write()

device: KOZ-AL00, Android 10

My another works fine.
It's a bug with device or plugin?

Hi @trayvon2017

Usually this kind of problem is a device issue.

Having said that, what are the symptoms you're seeing here? What MTU size are you requesting?
