Dear ST Support Team,
I am using STM32WB55 with firmware stm32wb5x_BLE_Thread_dynamic_fw.bin release V1.23 and application based on samples in STM32CubeFW. I flashed two devices and set both devices:
and coap capabilities.
I noticed the following behaviour:
Device1:
Device2:
Both devices have the same extAddr and same IPv6! (eui-64 read thanks otLinkGetExtendedAddress(...) ).
If I use otLinkSetExtendedAddress(...) with extAdrr coming from reading at @UID64_BASE (according to user manual Flash 64 section) I've got:
Device1:
Device2:
They still have the same IP address: fdeb:6e2:6135:d326:23d4:335f:27aa:3a48!
Any idea where I have to look for to avoid such behaviour? Because right now devices are only able to react on put/post multicast coap messages.
Thanks in advance.
Kind regards.
Philippe.
