Okay so I've bought several pre-flashed MDBT42Q modules from the Espruino shop previously, but I wanted to try it on my own so I bought some blank ones. I connected the module to a 32khz crystal with 22pf caps, then connected its swd pins to my NRF52DK but I can never get anything on it. Not even a simple blink program. I double checked all my connections and used everything from simple drag-n-dropping to nrfGo studio. I also tried the same without an external crystal. What am I doing wrong? I designed a whole PCB for this and I would love to get answers.
