Hi, has anyone interfaced with the SX1272 using the nRF52840? Perhaps they could point at us some LoRa SDK or libraries which will help the development process?
Thanks
Would a wire-wound inductor work better than a chip inductor for the antenna circuit of NRF52810? I'm using the 32 pin QFN package with the LDO configuration which calls for...
