Is ble_app_uart broken in nRF5_SDK_11.0.0_89a8197?

[Mahesh Venkitachalam]

I built the ble_app_uart example app using GCC with nRF5_SDK_11.0.0_89a8197, and on testing it with the latest version of Nordic nR ToolBox (iOS) and nRFMaster Control Panel (Android), I am finding that the app hangs and then disconnects soon after connecting. (I used the default S130 softdevice.)

Putting printf statements in on_ble_evt confirms connect/disconnect events.

On disconnection:

p_ble_evt->evt.gap_evt.params.disconnected.reason is 0x22.

BLE_HCI_STATUS_CODE_LMP_RESPONSE_TIMEOUT   0x22

I am able to build, upload and test the ble_app_hrs, ble_app_cscs and other non NUS apps fine with nRFToolBox.

I don't think the code is crashing, since I am able to see printf/uart messages from the nRF main loop in a terminal window even after the disconnect.

Any thoughts on what might be wrong?

Thanks!

Saw your case in support portal, sorry for late reply, we had a holiday in norway yesterday, I tried the nordic UART android app with SDK11 on PCA10028 . It did not disconnect even after 5 minutes now.

Thanks. Unfortunately it doesn't work for me. I've tried 2 different phones now. I think the issue is with the app, not with the firmware, because I can use LightBlue on OS X to communicate with the device running ble_app_uart.

which version of the app did you use on Android? and what is your phone brand and Android version on it? maybe i find similar specs here to test.

I have Samsung Android 6-0-1 and tested with latest version in the playstore. Tested it again a HUWAI phone lying around and it is working fine. I do not have Asus Zen phone or lower android version to try with :( ..
