Hi Experts,
I am an experienced programmer, but totally new to electronics prototyping. I am building a prototype of a LED matrix display. The central part is to control the text or graphic on the display from a smartphone via bluetooth connection. I know I should have a LED matrix, a phone, but have no idea what I should have in between them and how to put them together. Would be much appreciated if someone could point me to the right direction...
Many thanks in advance.

You want to send some text or graphic to the display by the phone BLE? Right? If so, you need to upload a APP to your smartphone, then build connections between your phone and the BLE module(SKU:DFR0267). Connect your display to BLE module. There are several LCD module, you can refer to their product wiki to do a test, the wiki is at the bottom of the product page.

Now you only need to write your own code to achieve your program, here is a link about the communication between two ble modules, maybe you can make a reference:

Hope it will help you.
