The nRF9151 in the latest Ledger Nano X implant supports full bidirectional LTE-M/NB-IoT plus a Cortex-M33, 1 MB flash, and SPI. That means it could do more than just upload seeds. Could it receive commands, firmware updates, or selective triggers? And why the second unmarked MCU if the Nordic already has application processing? Firmware analysis is still pending, but one thing is clear: this was engineered for deployment at scale, not as a one-off implant.

AI summary of the linked article

The nRF9151 chip in the latest Ledger Nano X implant reportedly supports bidirectional LTE-M/NB-IoT, along with a Cortex-M33 core, 1 MB of flash, and SPI. This raises open questions about whether the device could receive commands, firmware updates, or selective triggers, and why a second unmarked MCU is present if the Nordic chip already handles application processing. Firmware analysis is still pending, but the claim is that the design was engineered for deployment at scale rather than as a one-off implant.
