esp32c3 wifi和ble共存 导致wifi性能降低很多正常吗
idf5.5
wifi nimble共存跑iperf tcp
0.0-30.0 sec 1.2 Mbits/sec
关闭nimble 仅仅 wifi 跑iperf tcp
0.0-30.0 sec 11 Mbits/sec
差距这么大的吗

ESP32CE MQTT 断线重连后内存未释放问题
idf v5.2.1
开启mqtt 连接手机wifi 然后关闭数据流量和打开数据流量(模拟网络超时) esp_get_free_heap_size 获取到的内存越来越小 ,只有wifi重连才会释放内存
mqtt组件里面发送数据采用esp_transport_write发送的数据,esp_transport_write发送数据是直接发给tcp 吗 ,不知道怎么释放内存
