Hi everyone,
In nRF9160 with ncs 2.9.0 I've problems when trying publish a MQTT payload bigger than 2700 bytes aproximately. In advanced I already was adequated buffer size and put
"CONFIG_MQTT_MESSAGE_BUFFER_SIZE=4096 CONFIG_MQTT_PAYLOAD_BUFFER_SIZE=4096" lines in my prj.conf. I can't see faults in application log, but no data is received on broker. Looking for possibles llimitations in hardware, I figure out that 91 series modem have a limit on socket size of 2kb. Can I work around of this limitation by any other approach?
Send payloads up to 4096 bytes is an project requirement, and split payload in smaller parts is not an option at now.
Thanks for some help!
