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 17, Band 20 and memory component). u-blox has introduced changes with new product type numbers to ensure TOBY-L2 product availability. The products with new type numbers include new firmware and hardware versions.
Hardware Changes Description
Description of the hardware changes in each type number:
| Old Type Number | New Type Number | Description of HW Changes |
|---|---|---|
| TOBY-L201-02S-00 | TOBY-L201-02S-01 | Single band power amplifier LTE FDD B17 replaced with another PA electrically equivalent. System memory replaced with another equivalent memory component. Copper balance introduced to improve PCB coplanarity. |
| TOBY-L200-03S-00 | TOBY-L200-03S-01 | Single band power amplifier LTE FDD B17 replaced with another PA electrically equivalent. System memory replaced with another equivalent memory component. Copper balance introduced to improve PCB coplanarity. |
| TOBY-L210-03S-00 | TOBY-L210-03S-01 | Single band power amplifier LTE FDD B20 replaced with another PA electrically equivalent. System memory replaced with another equivalent memory component. Copper balance introduced to improve PCB coplanarity. |
| TOBY-L280-03S-00 | TOBY-L280-03S-01 | System memory replaced with another equivalent memory component. Copper balance introduced to improve PCB coplanarity. |
| MPCI-L201-02S-00 | MPCI-L201-02S-01 | Single band power amplifier LTE FDD B17 replaced with another PA electrically equivalent. System memory replaced with another equivalent memory component. |
The firmware of the module has been updated in order 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:
| Old Type Number | Current Firmware Version | New Type Number | New Firmware Version |

4 Schedule
Estimated First Shipment Date: 23. Dec 2019
5 Customer Impact and Recommended Action
u-blox has taken utmost care to ensure full backward compatibility to the previous versions. Successor products are pin-to-pin compatible to its predecessor.
Modules with the old type number can be upgraded with new firmware version. New Firmware can be downloaded to the TOBY-L2 module using 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) are also 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 request; no testing is expected.
For country approvals, u-blox recommends that customers contact their preferred certification body to verify if any action is needed. For example FCC and ISED 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 contact at the operator to find out what is needed to align to the updated versions; no testing is expected.
Note that any new operator certification shall be initiated using the latest type number.

² For each change and bug, the external and the internal references are reported with this notation [external reference / u-blox reference]
A.1.3 Known limitations
- [u-blox ID 1-2402] AT+CFUN=4,1 causes IMS to not restart. Workaround: send the command: AT+UIMSCONF="KEY_UIMSRESET",1 which triggers IMS to start back and also resets the +CIREG URC status to 0.
- [u-blox ID 1-2390] The "operation not allowed" error result code is sometimes returned as "Operation not allowed", they are the same error.
- [u-blox ID 2-2163 / u-blox ID 1-2226] After the +CFUN=19/1 cycle, the +UUICC read command returns "SIM not inserted" until the SIM is initialized.
- [u-blox ID 1-2105] In VZW configuration +UMNOCONF: 3,7, the following settings are not stored in NVM after SW reset +CGSMS and "KEY_MO_SMS_FORMAT" (+UIMSCONF AT commands key).
- [u-blox ID 1-2078] In VZW configuration: when a SMS is stored in "SM" memory in text mode (AT+CMGF=1), the <scts> field does not contain the value of the service center time stamp. Workaround: use the PDU mode (AT+CMGF=0).
- [u-blox ID 1-2076] Do not close the MUX ports immediately after the termination of a dial-up. It is recommended to wait 3 s.
- [u-blox ID 2-728 / u-blox ID 1-1920] All the MUX ports shall be opened simultaneously.
- [u-blox ID 1-2030] During PPP startup some unexpected strings may be sent by the module. Workaround: ignore these strings.
- [u-blox ID 1-1996] The preferred operator list command (+CPOL) is not available in +COPS: 2.
- [u-blox ID 1-1980] In +UCGED the LTE indicators <mmeGrId> and <mmeCode> may be wrong.
- [u-blox ID 1-1928] Use +CESQ for RSSi level indication in LTE RAT instead of +CIEV.
- [u-blox ID 1-1911] Wrong +UUSORF indication when there are more packets to read available. The URC notifies only the size of next available packet to read.
- [u-blox ID 1-1906] Downloading a file in the file system at high baudrate (921600 b/s) can lead to data corruption. Workaround: decrease the UART baudrate to 115200 b/s.
- [u-blox ID 1-1870] The +CMGW and +CMSS AT commands shall not be used on VZW network. Workaround: use +CMGS instead.
- [u-blox ID 1-1188] After deleting a PDP context with +CGDEL, if the context is later re-defined, all previously existing associated data (QoS profiles, TFTs) will reappear.
- [u-blox ID 1-804] The +URAT preferred values are not always respected when the setting is done with the sequence +COPS=2, +URAT, +COPS=0. Workaround: use the sequence +CFUN=4, +URAT, +CFUN=1.
