You can't turn the modem on and off more than once every other minute. Try a longer k_sleep() interval.

We have tried with 3 different Hologram SIMs and does not work. We have also verified that the problem is not the SIM, because we have successfully sent a Telegram message using a Raspberry+IOT modem + Hologram SIM.

What if you change SIM?

Hello,

One week ago Telegram Bot API updated the minimum TLS version to 1.2. For the code you gave me, I understand that I am using 1.2v TLS version, so should work fine:

int client_fd = socket(AF_INET, SOCK_STREAM, IPPROTO_TLS_1_2);

Can anyone confirm that the version of TLS is 1.2?

However, do you have any intention to include TLS 1.3v that was released in 2018?

Thanks a lot.

No, it does not work any more. I have tried to reset the device and also to re-upload the merged.hex but nothing has changed.

[quote user=""]It works fine but after 1-2 days working I am getting an error at this part of the code:[/quote]

Does it work again after you reset the device?

I always close the project and the Segger Studio before applying any change to prj.conf and clean build directory.

Concerning to Errno 22, that means Invalid Argument, I can't understand why it fails because it worked fine for 1-2 days.

I will wait for a Nordic Engineer answer or to someone that tests my code.

Thank you.

Some error codes are in the file errno.h, errno = 22 is EINVAL, or Invalid argument.

After editing prj.conf you have to close the project in Segger, then delete the build directory, then import the project again. The reason is that when a project is imported prj.conf is read in order to generate other files. If deleting the build directory and re-importing the project is not done then changes to prj.conf will not take affect, This is a bug in the build procedure.

Hello;

I have made some test with the NRF9160 DK:

I have updated to v2.1.99-ncs1-rc1 from v1.4.99 I think. After that "-1163019603" Errno disappeared and now I get "22" errno. The only change I have needed to make is to comment "#CONFIG_NET_RAW_MODE=y" line in prj.conf.

Do we know what does errno "22" mean?

I will attach here my code to send a Telegram message. Can anyone try to run it? It is not necessary to make any change. If so, the code should send a message to my telegram account.

Thanks for your support.

I don't know what that error code means, but -1163019603 in hex is FFFF FFFF BAAD BAAD‬ which looks like a generic error message.

Hi;

My program checks if the Telegram Bot has any receiving message. If so, the program replies to that message and then disconnects LTE connection. It repeats the process over and over again. So it does not send a lot of messages, but it is checking every minute if it has messages. The process is:

1.-Establish LTE connection. (modem_configure())

2.-Check for messages.

2.1.-Reply for messages

3.-Disconnect LTE. (lte_lc_offline())

4.-Sleep 1 minute.

It would be nice to know that does "-1163019603" errno mean.

I have also reflashed lastest modem firmware but nothing changed.

I have also try to make an HTTP request for IFTTT service and works fine.

Thanks.

Hi;

I am using Hologram IoT SIM.

Hello,

Are you by any chance using an iBasis SIM?

RE: HTTP send errno -1163019603

CWallach — Mon, 10 Feb 2020 19:22:39 GMT

How many messages do you send until it starts to fail?

I found that repeated HTTP messages would start failing and modem firmware get into a permanent failure state. Then I added

lte_lc_offline();

after each message and its been stable.

Hi,

Please I need some help, something to try. Any help or idea is welcomed.

Thanks.

Hi,

I don't know if it is related, but the NFR9160 is connecting to LTE, checking if there are Telegram messages, disconnecting from LTE and entering in low consumption mode over and over again. Maybe I have reached some limit.

Or maybe something got corrupted and I need to perform a factory reset...

Thanks.
