Failure connecting to example.com while running sample: https_client

Jacek Majda

After programming the sample to my nRF9160 DK, I opened the terminal emulator and I observed the following messages:

1. HTTPS client sample started

2. Provisioning certificate

3. Waiting for network..OK

4. Connecting to example.com

5. connect() failed, err 116

I am using the following:

1. nRFD9160 DK v0.8.2

2. Windows10 O.S. version:20H2, OS build:19042.631

3. nRF Connect v 3.7.0

4. nRF Connect SDK v 1.6.1

I attach the log file from the LTE Link Monitor below:

    Hello Marcus,

    I have resolved the problem which you didn't like in my log file from AT_client sample on line: Debug modem<<+CEREG: 5,2,"5209",...by adding the following line to the prj.conf file for this sample: CONFIG_LTE_NETWORK_MODE_NBIOT=y  (to set the modem to the NB-IoT mode).

    I attach the log file for this sample, that was created after implementing this change to the prj.conf file, which shows new data on this previously problematic line, namely: Debug modem<<+CEREG:5,1,"5209",..., indicating that now the registration was successful.

    As I wanted to use AT commands with the https_client sample  to verify that the modem is ON and that the modem is set to the NBIoT mode, I added these two lines to the prj.conf file for https_client sample:

    CONFIG_AT_HOST_LIBRARY=y

    CONFIG_UART_INTERRUPT_DRIVEN=y

    I attach below the copy of the modified prj.conf file for the sample https_client:

    Fullscreen prj-conf file for sample https_client 2021-09-07.txt Download 
    CONFIG_NRF_MODEM_LIB=y
CONFIG_NRF_MODEM_LIB_SYS_INIT=n

CONFIG_NETWORKING=y
CONFIG_NET_SOCKETS=y
CONFIG_NET_SOCKETS_POSIX_NAMES=y
CONFIG_NET_NATIVE=n

CONFIG_HEAP_MEM_POOL_SIZE=4096
CONFIG_MAIN_STACK_SIZE=4096

CONFIG_MODEM_KEY_MGMT=y
CONFIG_LTE_LINK_CONTROL=y
CONFIG_LTE_AUTO_INIT_AND_CONNECT=n
CONFIG_LTE_NETWORK_MODE_NBIOT=y

CONFIG_NEWLIB_LIBC=y
CONFIG_AT_HOST_LIBRARY=y
CONFIG_UART_INTERRUPT_DRIVEN=y

    Subsequently, I run the https_client sample again and the same error message: "connect() failed, err 116" appeared.

    I then used the AT command  AT+CFUN?  to confirm that the modem was on. And it was.

    And then I used the AT command  AT%XSYSTEMMODE?  to confirm that the modem was set to the NBIoT mode. And it was.

    I attach below the log file for https_client sample that shows what I have described above.

    I wonder if there are any more changes required to the prj.conf file for sample https_client to ovecome the error: "connect() failed, err 116.

    For comparison, I attach below a copy of the prj.conf file for the AT_client sample that connects to the NB-IoT network without a problem.

    Also, I was told that the engineering samples for my nRF9160 DK v 0.8.2 are not compatible with the latest modem firmware versions.

    Could this be a reason for the problem that I am experiencing?

    Regards,

    Hello Marcus,

    I have resolved the problem which you didn't like in my log file from AT_client sample on line: Debug modem<<+CEREG: 5,2,"5209",...by adding the following line to the prj.conf file for this sample: CONFIG_LTE_NETWORK_MODE_NBIOT=y  (to set the modem to the NB-IoT mode).

    I attach the log file for this sample, that was created after implementing this change to the prj.conf file, which shows new data on this previously problematic line, namely: Debug modem<<+CEREG:5,1,"5209",..., indicating that now the registration was successful.

    As I wanted to use AT commands with the https_client sample  to verify that the modem is ON and that the modem is set to the NBIoT mode, I added these two lines to the prj.conf file for https_client sample:

    CONFIG_AT_HOST_LIBRARY=y

    CONFIG_UART_INTERRUPT_DRIVEN=y

    I attach below the copy of the modified prj.conf file for the sample https_client:

    Fullscreen prj-conf file for sample https_client 2021-09-07.txt Download 
    CONFIG_NRF_MODEM_LIB=y
CONFIG_NRF_MODEM_LIB_SYS_INIT=n

CONFIG_NETWORKING=y
CONFIG_NET_SOCKETS=y
CONFIG_NET_SOCKETS_POSIX_NAMES=y

CONFIG_LTE_AUTO_INIT_AND_CONNECT=n
CONFIG_LTE_NETWORK_MODE_NBIOT=y

CONFIG_NEWLIB_LIBC=y
CONFIG_AT_HOST_LIBRARY=y
CONFIG_UART_INTERRUPT_DRIVEN=y

    Subsequently, I run the https_client sample again and the same error message: "connect() failed, err 116" appeared.

    I then used the AT command  AT+CFUN?  to confirm that the modem was on. And it was.

    And then I used the AT command  AT%XSYSTEMMODE?  to confirm that the modem was set to the NBIoT mode. And it was.

    I attach below the log file for https_client sample that shows what I have described above.

    I wonder if there are any more changes required to the prj.conf file for sample https_client to ovecome the error: "connect() failed, err 116.

    For comparison, I attach below a copy of the prj.conf file for the AT_client sample that connects to the NB-IoT network without a problem.

    Also, I was told that the engineering samples for my nRF9160 DK v 0.8.2 are not compatible with the latest modem firmware versions.

    Could this be a reason for the problem that I am experiencing?

    Regards,

    Jacek
