Custom firmware for Vaisala RS41 and Graw DFM-17 radiosondes with support for amateur radio use. Ideal for tracking high-altitude balloons. Supported modes include APRS, Horus 4FSK mode, CATS, morse code (CW) and additional digital modes like WSPR and FT8 via Si5351.
I soldered the connector to the DFM-17 and attached the ST-Link V2 USB. The board lights up with all 3 LEDs, but the STM32-STM Link Utility can't find the Target. What next?
