ANDROID NRF Connect app: UTF-8 encoded text data gets truncated

[BMohan]

UTF-8 encoded text data gets truncated or completely lost when transferred from Android NRF connect app over BLE. However it works fine from the iOS NRF connect app. Please refer to the below example and attached screenshots for details. Does anyone know what could be the root cause?

Ex:
Android
Input 1: {"ssid":"test"}
Bluetooth device receives only `{"ssid":"test` and doesn't receive the remaining `"}`.Input 2: {"ssid":"test","pass":"password"}
Bluetooth device doesn't receive data at alliOS
Bluetooth device receives the correct data

Hi,

This might be caused by MTU. You could try the following steps:

1. Connect your app to your device.

2. On the connection tab select menu next to Server tab (3 vertical dots), then "Request MTU", type 517 and press OK.

3. In the nRF Connect in Settings/Connectivity enable "Auto request maximum MTU"

Best regards,
Dejan
