SDK backwards compatibility support for older SD

I was looking at this compatibility matrix, for SD and SDK. https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcomp_matrix_nrf52832%2FCOMP%2Fnrf52832%2Fic_rev_sdk_sd_comp_matrix.html Are SDKs meant to be backwards compatible with all older versions of SDs? Or is this not recommended? It seems like the answer is no, which would be fine to get confirmation. To provide context, if I have a device in the field running SDK v14.2, SD132 v5.1 and I want to upgrade my SDK, but I am not able to upgrade my SD132 and keep it at v5.1.0 is that ok to do? So I would try and use SDK v15.0 (next version up) with SD132 v5.1.0. Would like confirmation that is a bad idea before I go down the route of exploring trying to do that.

Problems with nRF5 SDK

Hello, I am using nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8. 1. While referring to the Nordic Semiconductor Infocenter . I observed that in nRF5 SDK v16.0.0 there is one option for "Experimental: IoT Examples" under the "Bluetooth low energy examples". But in nRF5 SDK v17.0.2, there is no such option for the "Experimental: IoT Examples" under the "Bluetooth low energy examples". So can you explain to me why it is deprecated in nRF5 SDK v17.0.2? 2. I have import the thread and Zigbee project from nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8. But a local Nordic sales representative recommended that zephyr is a preferred way to develop moving forward. I don't see many of the projects in nRF5 under Zephyr (like multi-protocol). So, trying to understand what's Nordic's plans regarding moving (nRF52833/840) to Zephyr? Should I continue with nRF5 or plan to move to Zephyr (if Nordic planning to or provide guidance for migrating nRF5 projects there)? Please advise. Thank

Error while sending AT commands to modem on Thingy:91.

Hi, I am getting error from socket() function. I cant find definition for AF_LTE family. I am using simple socket() as: socket(AF_LTE, 0, NPROTO_AT); It will compile but will give run time error and return -1. I am trying to program nrf9160 on Thingy:91 so to send AT commands to the modem. Is there any specific configuration that I should change under menuconfig? Is there anything I am doing wrong? I am using nrf sdk 1.4.1 for developing the firmware. Thanks in advance.

Thingy:91 IPv6 CoAP Server over NB-IoT

Hi, I want to run a CoAP server with Zephyr on a Thingy:91 over NB-IoT. Now I noticed that the Thingy only gets a private IPv4 address (10.x.x.x) from my provider which makes it impossible to connect to it. Now I thought that I might be able to use IPv6 to remedy this. After having a look at the Nordic Zephyr examples and at the Nordic Documentation I am not sure if this is possible. Does Zephyr on the Thingy:91 support IPv6 over LTE? And if it does can someone point me in the right direction? Best regards, Johannes

Antenne requirements nRF52840 - Antenna tuning

Hi, I have a question about the whitepaper nwp-017.pdf. It is described under the chapter "Equipment needed to tune an antenna" that you have to attach a coax cable where you want to measure the impedance. So to tune the antenna I have to measure behind the matching network? Or can I measure in front of the matching network with the embedding and de-embedding method (including the matching-Network)? What is the impedance at the output of the nrF52840 chip? We need the information for research and test. thanks in advance
