Overview
Supported TI development boards and Spotflow transport options.
The Spotflow Device SDK supports the following Texas Instruments development boards through TI's SimpleLink Zephyr downstream:
| Board | Zephyr board target | BLE | Wi-Fi |
|---|---|---|---|
| LP-EM-CC2340R5 | lp_em_cc2340r5 | Yes | No |
| LP-EM-CC35X1 (CC3551E) | lp_em_cc35x1/cc3551e | Yes | Yes |
Both boards require an LP-XDS110 or LP-XDS110ET debug probe for flashing. They use different TI SimpleLink Zephyr releases and must be built in separate West workspaces.
LP-EM-CC2340R5
The CC2340R5 supports the Spotflow BLE transport using TI SimpleLink Zephyr v3.7.0-ti-9.10.04. It has only 36 KiB of SRAM, so the sample uses reduced buffers and disables application metrics and built-in system metrics by default to reserve RAM for user logic.
LP-EM-CC35X1
The CC35X1 supports both BLE and direct Wi-Fi/MQTT connectivity using TI SimpleLink Zephyr v4.4.0-ti-10.10.00. Its first flash requires one-time device activation and factory programming.
Before flashing a CC35X1 for the first time, follow Set up flashing for TI CC35x1.
Choose a transport
BLE sends telemetry through a gateway, which supplies the Spotflow ingest key. Wi-Fi connects the CC35X1 directly to Spotflow over MQTT and stores an ingest key in the firmware configuration.
