Support for BLE on the CH32V208

[Frostie314159]

Hi, is BLE support for the CH32V208 planned?

Thank you for your interest.

BLE support for the CH32V208 is indeed planned. However, it's a complex task that requires some development effort, and its implementation may not be immediate.

I'll update when I have more concrete plans on the timeline.

Currently, https://github.com/ch32-rs/ch58x-hal has a proof-of-concept implementation of BLE on CH582 MCU.
The BLE APIs are almost the same as CH32V208's.

Hi, thanks for the quick response! Could you potentially send me an ELF binary of one of the C example programs for BLE? I don't have a working build environment, and I'd like to examine the binary. Potentially, we could reverse engineer the registers and build a rust only BLE stack.
