LAUNCHXL-CC2640R2: multi_role example does not work with Sharp128 display

Christian Leifels

Hello,

I tried the multi_role example from SDK 3.30.00.20 with the IAR compiler. As long as I use the UART to see the menu, everything works. Then I plugged on a Sharp128 display board because I wanted to use the UART for different purposes. I just changed "BOARD_DISPLAY_USE_LCD" to 1 and "BOARD_DISPLAY_USE_UART" to 0 and "BOARD_DISPLAY_USE_UART_ANSI" to 0 in the IAR project settings. The display works and shows the menu, but after some seconds I get an "ICALL TIMEOUT" error. How can I fix this?

Thanks and best regards,

Christian

Hello Christian,

Have you checked here for memory allocation issues? You can easily see any memory failures by enabling HEAPMGR_METRICS as described here:

http://dev.ti.com/tirex/explore/content/simplelink_cc2640r2_sdk_3_30_00_20/docs/blestack/ble_user_guide/html/ble-stack-3.x-guide/debugging-index.html#debugging-common-heap-issues

If you do in fact determine that you are out of heap memory, please look into using cache as RAM or AUX as RAM in your application which will increase the amount of heap available to the device.

You can also try to reduce the number of connection (MAX_NUM_BLE_CONNS) to free up some RAM for the heap:

Hi Eirik,

I reduced MAX_NUM_BLE_CONNS from 3 to 1. Now it works. I will try to change memory settings in order to be able to increase it later on again.

Thanks so far and best regards,

Christian
