سلام دوستان اطلاعات 5تا ماژول دیگه رو دارم جمع آوری میکنم(یعنی در واقع یه حسگر) وا با کمک ماژل nrf دارم میفرستم به سمت گیرنده . حالا من از این حسگرها 4 تا دارم که هر 4 تا دارند اطلاعاتشونو به صورت مستقیم به گیرنده می فرستند. مشکلی که من دارم در سمت گیرنده اطلاعات هر 4 تا حسگر و با هم نمیگیره.عکس و کد میزارم
متاسفانه پشت سر هم نمیگره یه حسگرو میگیره مثلا شماره 1 بعد حسگرها تا شماره 4 همگی اطلاعاتشون صفر نشون میده.بعدش حسگر 2باید بگیره میره حسگر 3 رو نشون میده
اینم کد گیرنده و یکی از حسگرها فرستنده
