FAQ

General#

What devices are supported by nRF Cloud?#

All Bluetooth LE devices that are compliant to the Bluetooth LE 4.2 and higher Specifications. IoT devices directly connected to the internet, e.g. via LTE-M, prepared to communicate with nRF Cloud

What gateways do you support?#

Nordic Semiconductor has developed a Bluetooth LE gateway for iOS and Android. Our gateway implementations follow the guidelines defined in the "GAP REST API" and "GATT REST API" Bluetooth SIG Whitepapers.

Why do I need a gateway for Bluetooth?#

Bluetooth is a short range technology that typically reaches a maximum of about 100 meters. To connect to the cloud, a gateway is required to extend that range and convert the Bluetooth protocol to IP.

Is the nRF Cloud phone gateway code public?#

The gateway code is public on GitHub.

What Bluetooth LE devices can connect to nRF Cloud?#

All devices that comply with the Bluetooth LE Specification 4.2 and higher.

What Bluetooth LE examples do you support?#

nRF Cloud supports all the Nordic Semiconductor peripheral SDK examples in addition to custom Bluetooth LE devices such as the Thingy and various demo applications.

What connection protocol is supported between a Bluetooth LE device and the cloud?#

nRF Cloud supports standard Bluetooth LE protocols between the Bluetooth LE device and the gateway and IP protocol between the gateway and the cloud.

Do you support 6LoWPAN over Bluetooth LE?#

This is planned for a future release.

What does it cost to use nRF Cloud?#

nRF Cloud is a free developer tool provided by Nordic Semiconductor.

iBasis SIM Cards#

See the iBasis FAQ on DevZone. It is a bit dated, so here are some minor corrections:

  • How can I determine how much data is left on my card? "Your nRF Cloud LTE device dashboard nRF Cloud SIM Cards page will show the status..."
  • How can I purchase additional data for my card? "The “Buy More Data” button will appear at the top of your nRF Cloud LTE device dashboard when your current data plan is almost depleted. It is always visible now."

FOTA#

Can FOTA jobs be cancelled?#

Yes, but only from the CREATED state. In progress jobs cannot be cancelled.

How many devices can be updated at once?#

Currently, there is no limit for how many devices can be specified in a single FOTA job.

What protocols does FOTA support?#

FOTA supports both REST and MQTT.

Can Bluetooth LE devices be updated?#

Yes! Both the device, and the gateway it is connected to must support FOTA.
