nRF9160 MQTT - Receiving large (over 2kB) messages causing a disconnect

[gotrentus]

Hi

MQTT large message receiving when trying to obtain certs from aws...  

Setup

Modem: 1.3.3

nRF Connect: 2.3.0

I have seen posts 254191 & 303100 that relate to this this and discuss a number of work arounds.  To replicate I have removed all custom code and running example code on the dk

Running serial_lte_modem example and implementing native_tls  

testing against aws iot core (secure) , and hivemq (unsecure)

The data limit is in the low 2300's as the payload/topic combined. This points me away from the 2kB secure buffer as mentioned in 303100

Increased buffers in the native overlay

also found and increased the below in slm_defines.h this has little effect.

// #define SLM_AT_MAX_RSP_LEN   2100

#define SLM_AT_MAX_RSP_LEN   4096

// #define SLM_MAX_MESSAGE_SIZE NRF_SOCKET_TLS_MAX_MESSAGE_SIZE

#define SLM_MAX_MESSAGE_SIZE 4096

any help much appreciated

Hi Trent,

Looks the following configuration in v2.3.0\nrf\applications\serial_lte_modem\overlay-native_tls.conf already satisfies your needs as long as the received package is smaller than 5KB.

# If larger TLS buffer is required for large CA chain,
# increase CONFIG_MBEDTLS_SSL_IN_CONTENT_LEN and
# CONFIG_MBEDTLS_SSL_OUT_CONTENT_LEN to 4096
# and CONFIG_MBEDTLS_HEAP_SIZE to 36864
CONFIG_MBEDTLS_SSL_IN_CONTENT_LEN=5120
CONFIG_MBEDTLS_SSL_OUT_CONTENT_LEN=4096
CONFIG_MBEDTLS_HEAP_SIZE=36864

I will do a test tomorrow to verify if it works or not and share with you my testing process and results.

Best regards,

Charlie

Hi Trent,

Sorry for the late reply. Just let you know overlay-native_tls.conf only helps TLS server and HTTPS client in SLM.

We don't have plan to support MQTT with Native TLS officially in this moment, but you can follow a previous discussion about how to enable native TLS with the SLM MQTT client.

Best regards,

Charlie

Hi Charlie, do you happen to have a working sample?

[Charlie]

Hi Trent,

Yes, the attached sample is modified from nRF9160: Serial LTE modem — nRF Connect SDK 2.3.0 documentation (nordicsemi.com) by following this reply from another case. Please be aware that this file is just for reference, there will be no bug fix or guidance for it since it is not fully tested.

ncs230_slm_shell_native_tls_mqtt_20230405.zip

I built the firmware with overlay-native_tls.conf.

Then tested with the test.mosquitto.org public MQTT server with TLS(8883 : MQTT, encrypted, unauthenticated) connection by sending a 5000Byte message from another MQTT client on PC. Here is the log:

Yay, that works, thank you.  I got the data over that link on port 8883 encrypted/unauthenticated, I have been unable to connect to aws or mosquito (8884) where client certs are used.

i have been playing with the certs, and i saw that stas was hitting a similar problem on ticket 299981.

attached is my log, one thing i noted is that if if load the certs via LTE Link Monitor > Certificate Manager,  i get different values when i perform a CMNG=1 (note 11110 and 22220 are the same cert loaded different ways once via pasting in the AT command) . I wanted to do this as i saw that Stas was using XCMNG to load certs for aws.

it is as if the CR & LF are not going in correctly...?

many thanks for your help so far
