BLE KW41Z Connection issue

kevin_lang — Wed, 30 Jan 2019 23:02:37 GMT

Hello,

Is there a good example for KW41Z with 2 concurrent connections.

I did one and when testing with mobile applications (did by a 3rd contractor), the 1st App connecting okay , while 2nd app (both Android and iOS) connected and then quickly KW41Z firmware received a Disconnection event.

Mobile developer said he didn't initiate disconnection, I also didn't call any API to disconnect, how could it happen?

Thanks you all in advance

Kevin

Hello,

Could you please try the wireless uart example with the IOT Toolbox? Does it work for you?

Regards,

Hello Estephania

Thank you! Yes, I use the wireless uart example and modified based on it , with the IOT Toolbox ,two connections is okay, but sometimes second connection status is always in Service Discovery (mAppServiceDisc_c), what can I do to make it in mAppRunning_c ?

=================================

typedef enum appState_tag
{
mAppIdle_c,
mAppExchangeMtu_c,
mAppServiceDisc_c,
mAppRunning_c
} appState_t;

Best regards,

Hi kevin.lang@cae.com‌,

Here you can find attached a document lab that explains how to add a second connection to the heart rate sensor application.

Hope this helps.

Best regards,

Miguel
