atiq4rahman commented 5 years ago

what if i make the following changes ?? In Header file increase the value of the MQTT_MAX_PACKET_LENGTH. ‘\Documents\Arduino\libraries\WioLTE_Cat_NB1_Arduino_Library-master\ublox_sara_r4_mqtt.h’ In Source file increase the txBuf, mqtt_packets, topic & msg size as per the requirement. ‘\Documents\Arduino\libraries\WioLTE_Cat_NB1_Arduino_Library-master\ublox_sara_r4_mqtt.cpp’.

Using inbuilt functions in header file to change the variables msg_length and len in order to change packet length field. void setPublishHandler(void (handler)(char topic, const char msg, size_t msg_length)); void setPacketHandler(void (handler)(char *pckt, size_t len));

This seems to be a SARA-R4 limitation.

See this question on the official ublox forum: [SARA-R4] MQTT publish payload limit?
