UART Application Problem

Hello all,

I'm stuck in the use of the UART.

I have used the code from the UART example and the UART application for iPhone. I'm using eclipse because I don't want to pay licences to KEIL if I can do it for free. So I have configure the makefile and the UART code is compiling and is executing in the nRF6310. I use for uploading the program nRF Studio with SoftDevice S110.

I have added some messages for traceability through the UART port at the init and it works. LED 0 gets ON. Then I connect the Ipod and LED 0 -> OFF and LED 1 -> ON. Then I send a message from the Iphone and the nRF get stuck and the app disconnects.

When using the debugging with Eclipse, most of the times it blocks at the call BLE_STACK_HANDLER_INIT from ble_stack_init.

What I'm doing wrong? Could anyone that has encountered similar problems give me some hints?

Thanks in advance. M.

  • Thanks for the tip about Eclipse debugging. I use Eclipse for almost every kind of development I do.

    However, I also use the typical tracing through serial port to see the execution point and still it gets stuck at the connection level. I saw that I can send messages from the terminal (uart connection) to the iphone but if I do nothing for more than 3 seconds, the nRF blocks.

    And if I send a message from the iphone to the nRF, it blocks also inmediately (no possibility even to trace anything).

    Have anyone had a similar problem with this application?

    Regards, M.

  • Please make sure that your app_error_handler does not do a reset, and try to halt the chip there to see if an error of some kind occurs.

    By default, the error handler does a reset, so if some kind of error occurs, the device will reset directly, and abruptly ending any UART communication.
