Mavros: استمر في إسقاط الرسالة وقال "تجاوز قائمة انتظار الإرسال" عند نشر موضوع إلى mavros / setpoint_raw / local

فريقي العزيز،
هل يمكنكم يا رفاق تقديم بعض المساعدة أو النصائح حول هذا الموضوع.

ليس لدي أي فكرة عن مكان تصحيح هذا الخطأ ، فأنا أستخدم نفس الكود ، لكن هذا الخطأ ظهر للتو في اليوم الثاني ، ويبدو غريبًا.

تفاصيل المشكلة

أنا أستخدم وضع OFFBOARD للتحكم في الطائرة بدون طيار لتطير في الداخل ، ولدي مستشعر عمق وعلامة مرئية كتعليقات واستخدام التحكم في السرعة. ولكن عندما أنشر الرسالة إلى / mavros / setpoint_raw / local بسرعة 100 هرتز لعدة ثوانٍ ، ظهر الخطأ ، ويبدو أن الطائرة بدون طيار لا يمكنها تلقي أي رسائل ، أختبر معدل نشر متعدد و pixhawk مختلف (2 و 4) لا يزال الخطأ موجودًا.
أنا ضائع تمامًا. يرجى إعطاء التوجيه.

إجراء الإطلاق الخاص بي:
