Dear Everyone,
I created a custom STM32WB55 board taking hardware consideration from the RF hardware guide. Instead of a discrete matching network that was used on the Nucleo, we used IPD (integrated passive device), which was pretty much the equivalent. Based on pg.32 of AN5165. The schematic and the actual PCB design are shown below. The custom MCU of the custom board was ok, I could load firmware, debug and code just fine, but when I tried the BLE, I could not even detect the device on the BLE toolbox. I tried the Beacon sample firmware still nothing can be seen.
Can someone help me with this issue, or has somebody encountered the same problem?
I’ve exhausted the net, scouring for a possible solution, but it is hard. That is why I’m asking for somebody’s expertise regarding this.
