3 Description of Change

Component suppliers have announced end of life (EOL) for specific components currently used in TOBY-L2 products (Power Amplifier operating on Band 20 and memory component). u-blox has introduced changes with new product type numbers to ensure TOBY-L210 product availability. The product with the new type number includes new firmware and hardware versions.

Hardware Changes

Table 1: Description of the hardware changes

The firmware of the module has been updated to support the alternative components. The firmware appropriately configures and controls the components to ensure full compatibility in the general operations of the module. The version of firmware can be identified according to the type number as follows:

Firmware Changes

Table 2: Description of the firmware changes

For full details of changes contained in this new version, see Annex A.

The modem and application version can be polled from the module by sending AT+GMR and ATI9 commands. See u-blox AT commands manual [1] for details.

4 Schedule

Estimated First Shipment Date: 19-Apr-2020

5 Customer Impact and Recommended Action

u-blox has taken utmost care to ensure full backward compatibility to the previous versions. The successor product is pin-to-pin compatible to its predecessor.

Modules with the old type number can be upgraded with the new firmware version as outlined in Table 2 above. New firmware can be downloaded to the TOBY-L2 module using a serial interface (USB/UART) or over the Air (FOTA).

After old type numbers have been upgraded with the new firmware version, downgrading to old firmware is no longer possible.

Certifications and approvals available for predecessor products (with old type numbers) have also been achieved for the successor products (new type numbers) [A.2].

PTCRB / GCF certification grants have been updated. Customers shall align their products to the updated versions. For example, on the PTCRB/GCF website, the customer shall select the new listed version of the u-blox module and submit a request; no testing is expected.

For country approvals, u-blox recommends that the customer contacts their preferred certification body to verify if any action is needed. For example, FCC and ISED approvals have been updated but maintain the same IDs; no action is needed if the same module ID is re-used.

RED customers shall update their technical documentation using data relevant for the new type number.

Operator approvals have been updated. Please check with your operator contact to find out what is needed to align to the updated versions; no testing is expected.

A.1.2 Changes and issues fixed

1 For each change and bug, the external and the internal references are reported with this notation [external reference / u-blox reference]

• [CA-038557 / u-blox ID 2-2838] If triggered and failed due to entrance into out of service, the EPS bearer deactivation required by +CGACT is not effective in NAS despite it is confirmed at AT interface.
• [CA-038915 / u-blox ID 2-2840] The +COLP URC is not meaningful when the connected line identity is not available (e.g. due to interworking or presentation restrictions).
• [CA-040298, CA-039773 / u-blox ID 2-2948] RNDIS may not work if linux Kernel version is higher than v.4.8 and RNDIS driver optimization is enabled via AT+UDCONF=67,1.
