Hello everyone ! especially Hifikat! We recently connected a long-range antenna to the LoRa - SX1278 module, this cable passed near the RTC module of the KC868-A6 module, on occasions when we put the backup battery in the RTC Socket, our finger when making contact with the battery and being near the crystal, we have noticed that the RTC readings are beginning to fail, so we thought about placing a metal casing to protect this part of the circuit, we also thought about grounding the negative of the module to ground, is it okay to do this? What other recommendations could you give us for this situation? In advance thank you very much for your attention !
