I programmed a microcontroller to return received text data from BLE using UART.
However, I can get only 4 alphabet clearly and the next alphabet becomes broken.
For example, If I send the text "aaaaaa", then the microcontroller return "aaaa0(9)??" or "aaaa,(<)??"
The broken text is quite random.
I'm sending a text using my custom program after transforming it to UTF8.
I programmed the microcontroller below to return text in the event handler code in custom_stm.c.
====================================================
char* text = (char*)(attribute_modified->Attr_Data);
char output_text[strlen(text) + sizeof("received data: ") + 1];
sprintf(output_text, "received data: %s", text);
APP_DBG_MSG(output_text);
APP_DBG_MSG("\n");
=====================================================
I think it may be problem of number of packet.
Is there any suggestions?
