Moin Karl-Heinz, danke fuer den patch, mein NTP funktioniert damit 1a: ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== *adsb .PPS. 1 u 66 64 67 4.220 -3.637 4.774 192.168.178.241 .PPS. 1 u 1 64 167 27.755 -1083.7 728.989 Matthias  

@Karl-Heinz Lohner Danke für das debuggen und die Fehlerkorrekur. Ich denke das in den nächtsen zwei Tagen dann auch die Software mit den änderungen als Zip bereit steht und das Git Repository angepasst ist.  Mit freundlichen Grüßen Mathias

Hallo, nach ein parr Änderungen funktionert  der mini-ESP32-NTP. UBuntu und Windows 7 akzepieren den NTP Server.

How do I program this base and propeller?

Hallo, mit meiner Entwicklungsumgebung: 180622_1_1-11.zip Arduino IDE 1.8.10 Arduino-esp32 1.0.4 crashed det ESP32 während "packet.write" mit einer assertion: Switch to PPS Update RTC Timestamp is 1571554227 Timestamp is 1571554227 assertion "pbuf_free: p->ref > 0" failed: file "/Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/lwip/lwip/src/core/pbuf.c", line 765, function: pbuf_free abort() was called at PC 0x400ed617 on core 1 Backtrace: 0x4008d008:0x3ffcf630 0x4008d239:0x3ffcf650 0x400ed617:0x3ffcf670 0x4010f0ab:0x3ffcf6a0 0x400df8d7:0x3ffcf6c0 0x400df927:0x3ffcf750 0x40088f81:0x3ffcf780 Rebooting... ets Jun  8 2016 00:22:57 Dies kann durch die Änderung: udp.onPacket([](AsyncUDPPacket packet) { in udp.onPacket([](AsyncUDPPacket& packet) { behoben werden. Leider akzeptiert der ntpdate meines 18.04.3 LTS (Bionic Beaver) den ESP32-NTP nicht als NTP Source: ntpdate[4691]: no server suitable for synchronization found Hier ein Auszug vom tcpdump: Ubintu: *.130, NTP: *.199 14:26:41.437389 IP (tos 0x0, ttl 64, id 49538, offset 0, flags [DF], proto UDP (17), length 76)     192.168.2.130.123 > 192.168.2.199.123: [bad udp cksum 0x86e3 -> 0x2604!] NTPv4, length 48         Client, Leap indicator: clock unsynchronized (192), Stratum 0 (unspecified), poll 3 (8s), precision -6         Root Delay: 1.000000, Root dispersion: 1.000000, Reference-ID: (unspec)           Reference Timestamp:  0.000000000           Originator Timestamp: 0.000000000           Receive Timestamp:    0.000000000           Transmit Timestamp:   3780649601.437255331 (2019/10/21 14:26:41)             Originator - Receive Timestamp:  0.000000000             Originator - Transmit Timestamp: 3780649601.437255331 (2019/10/21 14:26:41) 14:26:41.498058 IP (tos 0x0, ttl 255, id 94, offset 0, flags [none], proto UDP (17), length 76)     192.168.2.199.123 > 192.168.2.130.123: [udp sum ok] NTPv4, length 48         Server, Leap indicator:  (0), Stratum 1 (primary reference), poll 3 (8s), precision 0         Root Delay: 0.000015, Root dispersion: 0.000015, Reference-ID: PPS^@           Reference Timestamp:  2208988800.000000000 (1970/01/01 01:00:00)           Originator Timestamp: 0.000000000           Receive Timestamp:    3780649602.000000000 (2019/10/21 14:26:42)           Transmit Timestamp:   3780649602.000000000 (2019/10/21 14:26:42)             Originator - Receive Timestamp:  3780649602.000000000 (2019/10/21 14:26:42)             Originator - Transmit Timestamp: 3780649602.000000000 (2019/10/21 14:26:42) Sind Reference Timestamp, Originator Timestamp und Originator - Receive Timestamp, Originator - Transmit Timestamp wirklich OK? Die BAD Checksum vom Ubuntu scheint nicht zu stören. Da meine FB als NTP Server akzeptiert wird. Karl-Heinz
