Many many thanks for your support!!

Hi Stefan,

again many thanks. It works now. I can send data to my App. The following sequence works for Quectel BC66:

Deactivate auto sleep mode

AT+QSCLK=0

Persistent network and APN setup

AT+QBAND=1,8
AT+CFUN=0
AT*MCGDEFCONT="IP","cdp.iot.t-mobile.nl"

Restart the module as some configurations only take place after a reboot.

AT+QRST=1

After reboot wakup from sleep, deactivate auto sleep mode again and wait for network connect

AT+QSCLK=0

+IP: 10.128.0.134

Create a UDP socket and for UDP server

AT+QIOPEN=1,1,"UDP","172.27.131.100",15683,1001,0,0

Send message “Hello World”

AT+QISEND=1,11,48656c6c6f20576f726c64

Hi Mario,

Tuino 096 is an Arduino Zero (M0) compatible board. Grove Base Shield V2.0 doesn’t support this explicitity.

I recommand to try"ARDUINO MKR CONNECTOR CARRIER (GROVE COMPATIBLE)" instead. With this shield you can bridge from Zero/M0 to sensors with Grove connectors.

Hi Joop,

I will fix this.

Could you please give me your IMEI?

… Now I got a diffrent IP 10.128.1.149. Still the same problem

Hi,

unfortunatelly I can not connect to UDP server of T-Mobile Netherlands

In the following the key infos about my scenario:

• I am using the Quectel BC66-TE-B development kit
• I am working with a IoT sim card from T-Mobile Netherland in Germany.
• The roaming for Germany is activated for the sim card.
• The APN is set to: cdp.iot.t-mobile.nl
• The device get assigned the IP address : 10.0.0.191
• The command: AT+QIOPEN=1,0,“UDP”, “172.27.131.100”,15683,1001,1,1
• As the result I got the error response: +QIOPEN: 1,565
• The code 565 means: DNS parse failed

I tryed to execute AT+QIOPEN for IPv4 and IPv6. In both cases I got the same problem.

Actually I think that the IP 10.0.0.191 looks very very strange.

I can setup the IP address of the DNS server explicity. Does anyone know it??

Many thanks for your help!
