Welcome to the Serial Modem wiki! This page contains some unofficial plans on what's coming up.

Here are rough plans for upcoming releases:

• v2.0.0-preview1: 02-Apr-2026
• v2.0.0: 30-Apr-2026
• v2.1.0: 18-Jun-2026
• v1.x.x: not planned but made on a need basis

New features for v2.0.0 release:

• Re-designed HTTP client: https://github.com/nrfconnect/ncs-serial-modem/pull/201
• Re-designed TCP server functionality: https://github.com/nrfconnect/ncs-serial-modem/pull/196
• nRF Cloud over CoAP (replaces MQTT): https://github.com/nrfconnect/ncs-serial-modem/pull/174
• CoAP client
• More standard and dynamic handling of CMUX channels: https://github.com/nrfconnect/ncs-serial-modem/pull/133

Other notes:

• v2.x.x releases are backwards compatible from AT command API point of view with v1.x.x.
• Full MFW FOTA is an exception which we are even thinking of removing since it's only practical for nRF9151 DK with external flash. Full MFW update through DFU would still be available and that is a more realistic approach for end products. If you have concerns on this, please contact our customer support.
