data lost when connected to android

[jawadk]

Hi,

I am using the sdk 14, S132, ble_app_uart example.

My nordic chip receives data from the MCU over UART and passes out to mobile application over BLE.

using the nrf connect app

with IOS:

with Iphone 5 s i lost data

with Iphone 7 it worked and i received the whole data correctly.

with android: 

I lost data.

Tried to change connection interval and MTU but it didn't work.

Do you have any suggest please !?

Hi,

I solved the issue.

just added a request MTU(247) from the App side before starting to listen to the notifications, and that solved the problem, and I started to receive all the data sent from the BLE device to the App Log.

Thank you for trying to help.

Best Regards
