NFC Commissioning timeout

[Mary]

I am using nRF5 SDK for Thread and Zigbee 2.0.0

I am having trouble commissioning using NFC, either with the nfc_meshcop example or my own code (based on the nfc_meshcop example).

After bringing the NFC antenna near the antenna on the Raspberry Pi based Border Router, I see the following messages after about a minute and a half:

[0000137496] -MESH-CP-: handshake timeout

[0000137496] -MESH-CP-: mbedtls_ssl_fetch_input() returned -26624 (-0x6800)

[0000137496] -MESH-CP-: mbedtls_ssl_read_record_layer() returned -26624 (-0x6800)

[0000137496] -MESH-CP-: mbedtls_ssl_read_record() returned -26624 (-0x6800)

Also, the function joiner_calback(otError error, void * p_context) is called with the 'error' parameter set to OT_ERROR_SECURITY.

The Raspberry Pi is running from the RaspPi_OT_Border_Router_Demov2.0.0-1.alpha.img

What do these messages mean? and how do I fix it?

Hi,

Have you tested to run unmodified applications from freshly extracted SDK version, to make sure that nothing have been modified?

Best regards,

Ok, so you are only seeing the issue when using the NCP with USB transport?

[Mary]

That is correct.
