Read / Write lwm2m resource instance

[ICM_UC]

Hi all,

I'm implementing a lwm2m client on a NRF9160 and have a problem with read/write resource instances. I use Leshan demo server to test the object and a came across a problem on ‘Remote SIM Provisioning’ object 504. When I read ‘504/0/11’ it reads all instances of this resource, but when I try to read a single instance of this resource, got an error. See images blow

Read resource insntances OK

Read single resource instace NOK.

This is my first problem, because after i need to write.

Can anybody help?

Hi Charlie,

I still need your help!

To correct this problem i need to change nordic lwm2m library and this is a problem because every time you update SDK i need to replicate all the changes.

How can we solve this problem?

Hi ICM_UC,

You can share your modification to the lwm2m library here. I will create an internal bug or improvement report after evaluating your solution.

Do you experience a similar issue with objects in the current nRF9160: LwM2M Client sample?

Best regards,

Charlie

Hi Charlie,

Yes, the same happens to objects in LwM2M Client sample.

I'm working on the changes needed to support Read/Write resource instances and then i'll post them here
