Features of Thingy:91

Nordic Thingy:91 is a battery-operated prototyping platform for cellular IoT systems, suitable for prototyping asset tracking, environmental monitoring and more. Thingy:91 integrates an nRF9160 SiP that supports LTE-M, NB-IoT, and Global Navigation Satellite System (GNSS) and an nRF52840 SoC that supports Bluetooth® Low Energy, Near Field Communication (NFC) and USB.

The following sections describe the various features of Thingy:91 apart from the ones on the Features of nRF91 Series page.

GNSS

Thingy:91 has a GNSS receiver, which, if activated, allows the device to be located globally using GNSS signals.

LTE Band Lock

For Thingy:91, you can configure the modem to use specific LTE bands by using the band lock AT command. See Band lock and the band lock section in the nRF9160 AT Commands Reference Guide for additional information. The preprogrammed firmware configures the modem to use the bands currently certified on the Thingy:91 hardware. When building the firmware, you can configure which bands must be enabled.

LTE-M / NB-IoT switching

Thingy:91 has a multimode modem that enables it to support automatic switching between LTE-M and NB-IoT. A built-in parameter in the Thingy:91 firmware determines whether the modem first attempts to connect in LTE-M or NB-IoT mode. If the modem fails to connect using this preferred mode within the default timeout period (10 minutes), it switches to the other mode.
