Issue with ble_app_uart and Taiyo Yuden module.

[Kraust]

I am trying to get the ble_app_uart project working on a Taiyo Yuden EYSGCNZWY using SDK 11 and the S130 Softdevice. The EYSGCNZWY documentation located here here states that the module supports the S120 softdevice, but there are some feature in the S130 softdevice that I need for my project.

I've made the code change to support the 32k Crystal as mentioned on the last page (and the BLE part works), however communication over the UART seems to stop working after the first few seconds. To me it looks like there's an issue in the configuration of the Crystal but I'm not sure exactly how to resolve this problem

ble_app_uart.zip

I've included a custom board configuration with the GPIO pins I'm using for the UART, and a 1 second timer for printing a ping over the UART. When the code is running this is the output:

After this the system seems to "lock up" and I am unable to use the reset switch, however it looks like the module is still advertising.

@Kraust: I would suspect that your device got an assertion and the code stuck in app_assert_handle. You can try to follow this guide to debug your application: https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/#60126

Note that S130 v2.0 may not be compatible with the nRF51 chip on your device, you may need to use S130 v1.0. We need to know which revision the chip in the module is to know if you can use S130 v2.0 or not.
