Thingy 91 - nRF9160 SICA B0A, Revision 1 - Firmware

Question

According https://www.nordicsemi.com/Products/Development-hardware/Nordic-Thingy-91/Download#infotabs 
 Version 1.2.7 seem to be the latest without "only for testing and development" for Revision 1 . 
 During the startup, I get 
 W: Enabling modem sleep notifications failed, error: 65536 W: Modem sleep notifications require nRF9160 modem >= v1.3.0 
 For me this looks like, that PSM is either not reported, or the Things is "only for testing and development". 
 Are there issues for PSM with the Revision 1? 
 Are there plans, to provide also software updates (without that "only for ...") for the Revision 1?

Hello Achim, 
 Achim Kraus said: Does Nordic plan to support the nRF9160 HW Revision 1 in future modem firmware updates, or not? 
 nRF9160 HW Revision 1 will only have support with modem firmware versions < 1.3.x. We do not have any plans to add new modem features/functionality to older HW revisions. 
 Regards, 
 Markus

Hello. For example AT commands AT%XMODEMSLEEP (modem sleep notifications) and AT%XT3412 (periodic TAU notifications) are supported by MFW 1.3.x series and its feature set. These commands are not part of "older" MFW 1.2.x series. 
 There are no HW limitations with PSM and Revision 1. 
 It is good to be aware of MFW and NCS compatibility matrix, introduced here: infocenter.nordicsemi.com/.../nrf9160_modem_fw.html
