Affected Products
All products with product options “-L”, “-Lbb” and “-Lg” for LTE Cat. 4 based on u-blox TOBY-L2xx modem are affected. Products using other cellular standards are not affected: e.g. LTE Advanced, LTE 450 MHz, GSM-R.
Product Change
The following changes in the firmware of the modems are the most relevant for NetModule customers:
- Under very rare circumstances, some units may fail to boot. The issue is evident predominantly at high
temperatures (e.g. 85 °C) while at lower temperatures normal module behaviour is typically restored. The issue has been observed on units belonging to a specific production lot (units produced in 2021). The root cause is related to a mismatch on refresh timing set for the RAM memory and the actual characteristics of specific RAM memory parts themselves. To solve the issue and improve product robustness, the new firmware implements new RAM refresh timing. - eSIM/eUICC feature supported with NRSW version 4.5 and 4.6 was improved (some provider profiles did not work with previous firmware version 17.00 A01.00). This point is relevant only if you have licensed the eSIM/eUICC feature of NRSW.
