Facing issues when ping count > 250 in SimplePing.ino

[2BECKHAM2]

Thanks for the nice library dancol90.

Upon checking I observed that the number of ping requests are not initiated based on the ping count that I configured.

*** CODE *

include

const int ping_count = 1100; const IPAddress remote_ip(8, 8, 8, 8);

void setup() { Serial.begin(115200); delay(10);

// We start by connecting to a WiFi network

Serial.println(); Serial.println("Connecting to WiFi");

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) { delay(100); Serial.print("."); }

Serial.println(); Serial.print("WiFi connected with ip ");
Serial.println(WiFi.localIP());

Serial << "Ping count configured : " << ping_count << "," << " Pinging ip : " << remote_ip <<endl;

if(Ping.ping(remote_ip, ping_count)) { Serial.println("Success!!"); } else { Serial.println("Error :("); } }

void loop() { }

When configured the ping count = 300, the ping requests are initiated only up to 44 times. The expected behavior is 300 times. I've listed the log details below.

WiFi connected with ip 192.168.31.178 Ping count configured : 300, Pinging ip : 8.8.8.8 Reply from: total_count = 0 resp_time = 48ms seqno = 1 timeout_count = 0 bytes = 32 total_bytes = 0 total_time = 0 ping_err = 0 .....

Reply from: total_count = 0 resp_time = 48ms seqno = 44 timeout_count = 0 bytes = 32 total_bytes = 0 total_time = 0 ping_err = 0 Avg resp time 49 ms Success!!

When configured for 400

WiFi connected with ip 192.168.31.178 Ping count configured : 400, Pinging ip : 8.8.8.8 Reply from: total_count = 0 resp_time = 49ms seqno = 1 timeout_count = 0 bytes = 32 total_bytes = 0 total_time = 0 ping_err = 0 ...... Reply from: total_count = 0 resp_time = 58ms seqno = 144 timeout_count = 0 bytes = 32 total_bytes = 0 total_time = 0 ping_err = 0 Avg resp time 55 ms Success!!

When configured for 1000.

Reply from: total_count = 0 resp_time = 55ms seqno = 231 timeout_count = 0 bytes = 32 total_bytes = 0 total_time = 0 ping_err = 0 Reply from: total_count = 0 resp_time = 50ms seqno = 232 timeout_count = 0 bytes = 32 total_bytes = 0 total_time = 0 ping_err = 0 Avg resp time 114 ms Success!!

Note that I am facing this issue only when I set the ping count to be > 250. The above conditions were simulated thrice and observed the same result.

Hi! Yes, this is expected, as the count parameter is of type byte. Hence it can hold at most 255. Checking the SDK headers, though, the ping_option struct uses uint32s, so maybe changing the ping function signature will suffice. I will give this a try as soon as possibile.

Many thanks dancol90 for the update.

Thanks for the excellent library Dancol90,

Do you have any update on the above.

Thanks in advance.
