@ESP_Angus Hi, Angus, I used the latest commit 9b30f66 for my project. I create a TCP server using netconn, and then got the issue. But when I use lwip socket API to establish connection with client, it seems no problem. Is there anything wrong with netconn lib?

I faced the same issue

@kolban Hi, Thanks for your advice. The target device is a nRF51822 device, which is not developed by me. I just want to connect to it and control it via ble.

I Solved it. Close issue

Hi,

Hi,
Is there a BLEDEMO APK for the blufi sample in esp-idf? I didn't find any download link in the README file. Can you provide one for users to download the APK. Thanks.
