Jared helped me solve this problem by increasing the workqueue stack size parameter from 2048 to 4096

// increasing this parameter fixed the error
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096

This was the error output that led us here:

Let me know if you are able to get it to work. I will try the sample in the meantime.

RE: (NCS / Zephyr) OTA DFU Failed: insufficient MTU: 20

Vidar Berg — Mon, 28 Jun 2021 14:45:08 GMT

Hi,

Sorry for the delayed response. I'm suprised it didn't work with the new configuration. Could you maybe send me the configuration file from your build (<your build folder>\zephyr\.conf) so I can try to compare it against a working project?

You may also try the original SMP sample project here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html. This sample should not require any modifications.

Hey Vidar Berg thanks for the quick response. However, I'm still getting an MTU error after adding these configuration parameters. See below for a screenshot. My new prj.conf file can also be found below with the additional parameters.

RE: (NCS / Zephyr) OTA DFU Failed: insufficient MTU: 20

Hi,

It seems like the default MTU size is set too low in your case. Please try to add the following config settings:

CONFIG_BT_BUF_ACL_RX_SIZE=251
CONFIG_BT_BUF_ACL_TX_SIZE=251
CONFIG_BT_L2CAP_TX_MTU=247
CONFIG_BT_CTLR_DATA_LENGTH_MAX=251

This should increase both the max. MTU size and maximum radio packet length.
