HI All, 

         I would like to add a service for UART read and I have modified the characteristic values that show as red word.

but I don't know how to setting the data size, could you please to tell me, if you know about that, thanks. 


PRIMARY_SERVICE_UUID128(service_wireless_uart, uuid_service_wireless_uart)
VALUE_UUID128_VARLEN(value_uart_stream,uuid_uart_stream,gPermissionFlagWritable_c|gPermissionFlagReadable_c), gAttMaxWriteDataSize_d(gAttMaxMtu_c), 1, 0x00)
