I wrote code for my micro:bit in [makecode.microbit.org](http://makecode.microbit.org). Idea is to use radio communication and send each micro:bit message. So my question at first was how many messages can get just one micro:bit? Internet say this: Messages received are read from a queue of configurable size (the larger the queue the more RAM is used). If the queue is full, new messages are ignored. Reading a message removes it from the queue. So my question is: how to find how much RAM memory is used on my micro:bit using makecode? ---

The queue is 5 messages. ---

Is there anyway I can change it? ---

Can you please write my code that show me a number of element in queue so that I can know which message will be lost? ---
