Hello, first time using this forum so I'm sorry if I placed this in the incorrect place.
I am working on a project and I decided I need Bluetooth. I'm not going to use any premade PCBs or modules, since I want to learn PCB design and other things, but that's besides the point.
I'm looking at this chip: DA14580-01AT2 since it's fairly cheap and I can't find a Bluetooth transceiver without an integrated MCU in the shop I want to buy it from; and also it doesn't require some fancy antenna matching network.
The problem I have is, I'm not sure wether or not this chip requires to be programmed - I just want an SPI/I2C/UART/USART interface to communicate via Bluetooth. It says it can be used as a stand alone SoC or as a data pump for a hosted system, but I can't find any info on how to use it with an external MCU, without programming the chip itself beforehand.
I was hoping I could get some help here, since I couldn't find any information elsewhere. Either that or I'm incapable of getting this info from the datasheet.
