**Just Barely Fitting a Full Wi-Fi Stack on the nRF9151** New post in which I walk through narrowly fitting wpa_supplicant and the @NordicTweets Wi-Fi driver into the nRF9151's limited RAM and flash, allowing it to control the nRF7002 on the Thingy:91 X.

New post announcing support for offloading @GoliothOfficial to run on @Qualcomm modem application processors! This frees up resources on external MCUs and creates the opportunity for drop-in modules that add a seamless and consistent connectivity interface for any device.

let’s build something great this week!

**Accessing the Qualcomm Modem over USB on the RAK5010** A short post on some recent rework I did on the @RAKwireless RAK5010 development board to access serial ports on the @Quectel_IoT BG95's @Qualcomm 9205 modem via USB.

This week at @GoliothOfficial I have: - Done PCB rework - Written embedded firmware - Written network and backend cloud services - Implemented new platform observability tooling - Moved some manual provisioning of infra into IaC It's a great time to join a full stack startup!

On the topic of SPARC, I enjoyed this clip from @hasheddan's conversation with Robert Garner:

**VPR: Arm and RISC-V Inter-Processor Communication** In my final blog post of 2024, I explore inter-processor communication between the @Arm Cortex-M33 and @risc_v VPR cores on the @NordicTweets nRF54H20 using the @ZephyrIoT IPC service.

**VPR: Nordic's First RISC-V Processor** I wrote about VPR ("viper"), the new @risc_v processor that is beginning to show up in @NordicTweets SoCs. We explore how to build @ZephyrIoT applications that target it, and how the app processor configures and starts it.

**USB UART on the Thingy:91 X** I wrote up a short post on accessing UARTs over USB on the new @NordicTweets Thingy:91 X via connectivity bridge on the nRF5340. https://t.co/oHdOMthVEb
