你好，我在建立一個稍微複雜的程式，其中使用了 - ap+sat模式的wifi - MQTT連線傳訊息 - 檢查一個GPIO的訊號 - RTOS分別處理wifi、MQTT、ap web server、GPIO的任務 我現在遇到不斷出現`[INFO] [ard_socket.c][send_data] err = 268870584` 的問題，而且在出現這訊息時，我的GPIO就算使用中斷也不會有反應，這個訊息出現頻率非常規律地約為7秒，請問怎麼辦? 以下是log ```auto 04:46:21.351 -> #calibration_ok:[2:19:11] 04:46:21.397 -> 0 04:46:21.397 -> 1 04:46:21.397 -> 2 04:46:21.397 -> saved SSID:willyNet 04:46:21.397 -> saved PASS:willy1510 04:46:21.397 -> 3 04:46:21.397 -> interface 0 is initialized 04:46:21.397 -> interface 1 is initialized 04:46:21.397 -> 04:46:21.397 -> Initializing WIFI ... 04:46:21.569 -> WIFI initialized 04:46:21.569 -> IPv4 enabled 04:46:21.569 -> 04:46:21.569 -> Starting AP ... 04:46:22.317 -> safebox_ap started 04:46:22.317 -> 4 04:46:28.317 -> 04:46:28.317 -> [INFO] server_drv.cpp: WiFi server is set to non-blocking mode 04:46:28.317 -> 04:46:28.317 -> [INFO] Listen socket successfully 04:46:28.317 -> 04:46:28.317 -> [INFO] Socket connect successfully 04:46:28.317 -> 5 04:46:28.317 -> 6 04:46:28.317 -> 7 04:46:28.317 -> 8 04:46:28.317 -> 04:46:28.317 -> RTL8721D[Driver]: set ssid [willyNet] 04:46:28.317 -> MQTT waitin9 04:46:28.360 -> setup dong for wifi e 04:46:28.360 -> 04:46:28.360 -> [Iconnection 04:46:28.360 -> NFO] [ard_socket.c][send_data] err = 268870584 04:46:28.360 -> 04:46:28.360 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:28.360 -> MQTT waiting for wifi connection 04:46:32.431 -> 04:46:32.431 -> RTL8721D[Driver]: rtw_set_wpa_ie[1160]: AuthKeyMgmt = 0x2 04:46:32.469 -> 04:46:33.057 -> RTL8721D[Driver]: rtw_restruct_sec_ie[4279]: no pmksa cached 04:46:33.090 -> 04:46:33.212 -> RTL8721D[Driver]: start auth to 04:95:e6:19:df:08 04:46:33.212 -> 04:46:33.212 -> RTL8721D[Driver]: auth alg = 2 04:46:33.212 -> 04:46:33.212 -> RTL8721D[Driver]: 04:46:33.212 -> OnAuthClient:algthm = 0, seq = 2, status = 0, sae_msg_len = 0 04:46:33.246 -> 04:46:33.246 -> RTL8721D[Driver]: auth success, start assoc 04:46:33.246 -> 04:46:33.246 -> RTL8721D[Driver]: association success(res=2) 04:46:33.246 -> 04:46:33.293 -> RTL8721D[Driver]: ClientSendEAPOL[1650]: no use cache pmksa 04:46:33.293 -> 04:46:33.293 -> RTL8721D[Driver]: set pairwise key to hw: alg:4(WEP40-1 WEP104-5 TKIP-2 AES-4) 04:46:33.293 -> 04:46:33.293 -> RTL8721D[Driver]: set group key to hw: alg:4(WEP40-1 WEP104-5 TKIP-2 AES-4) keyid:1 04:46:33.293 -> no MQTT connection.... reconnect MQTT 04:46:34.352 -> 04:46:34.352 -> [INFO]server_drv.cpp: start_client 04:46:34.352 -> [INFO] Create socket successfully 04:46:34.398 -> 04:46:34.398 -> [ERROR] Connect to server failed 04:46:34.398 -> 04:46:34.398 -> [INFO] [ard_socket.c][send_data] err = 268678275 04:46:34.398 -> 04:46:35.390 -> Interface 0 IP address : 192.168.0.104 04:46:36.111 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:36.111 -> 04:46:36.111 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:36.111 -> ========= reconnect MQTT fail ============== 04:46:36.111 -> ========= reconnect MQTT fail ============== 04:46:39.403 -> fail reason code=-4 04:46:43.183 -> 04:46:43.183 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:43.227 -> 04:46:43.227 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:43.227 -> no MQTT connection.... reconnect MQTT 04:46:44.425 -> 04:46:44.425 -> [INFO]server_drv.cpp: start_client 04:46:44.425 -> [INFO] Create socket successfully 04:46:44.425 -> 04:46:44.471 -> [INFO] Connect to Server successfully! 04:46:44.471 -> ========= reconnect MQTT success ============== 04:46:50.295 -> 04:46:50.295 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:50.295 -> 04:46:50.295 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:50.339 -> 04:46:57.441 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:57.441 -> 04:46:57.441 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:46:57.441 -> 04:47:04.540 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:04.540 -> 04:47:04.540 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:04.540 -> 04:47:11.625 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:11.625 -> 04:47:11.625 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:11.670 -> 04:47:18.756 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:18.756 -> 04:47:18.756 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:18.756 -> 04:47:25.874 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:25.874 -> 04:47:25.874 -> [INFO] [ard_socket.c][send_data] err = 268870584 04:47:25.874 -> ``` ---

Hi @liulk3 ， 您提供的log當中顯示non-blocking mode， 您試著換成blocking mode且把ap 關掉來查看有沒有問題。然後， 在試著把sta 關掉且把ap開來查看有沒有問題。 謝謝。 ---

我這裡有發現問題，你們提供的arduino API中，wifiClient的部分有一個operator bool()的功能，實作如下 ```auto #WiFiClient.cpp WiFiClient::operator bool() { return _sock >= 0; } ``` ```auto #WiFiClient.h uint8_t _sock; ``` 但\_sock的定義卻會讓這功能永遠為true，初步退測試在這裡出現了問題。 我會使用operator bool()原本是按照現在範例程式寫的，我另外使用了aWOT這個http server處理liberary，他應該會替我處理原本範例中while迴圈讀取的工作，才遇到這個問題。 我有看出你們在WiFiClient::connected() 這個功能做了unit8和int8的兼容，所以我目前先改用這個函式確認是否有連接，現在基本沒問題了。 現在官方github上提供的程式目前還是有這個問題，在arduino IDE的編譯過程也可以看到編譯器跳出很多因此而生的warning， **原廠的開發團隊應該注意此事。** ---

Hi @liulk3， 您説的在arduino IDE的編譯過程也可以看到編譯器跳出很多因此而生的warning是跑哪個範例和什麽warning log。 謝謝。
