HTTP send errno -1163019603

[isurki]

Dear Community;

I am using this code provided by a Nordic engineer to make some HTTP request in order to use Telegram Bot API. It works fine but after 1-2 days working I am getting an error at this part of the code: 

int num_bytes = send(client_fd, send_buf, send_data_len, 0);
if (num_bytes < 0) {
	printk("send errno: %d\n", errno);
	goto clean_up;
}

This is the error: "send errno: -1163019603"

The problem is that after first time this happens never recovers its normal functionality.

What is causing this error? How can be solved?

Any idea or suggestion 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.

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.
