Hi Salae Community, often times I need to view raw data coming from rf chips. Therefore, I would need support for a protocol with 8 data bits and no start, stop or parity bits. I want to be able to use Async Serial with 0 stop bits, to view the RF data in HEX. Thank you very much for any suggestions or replies! Niklas from 🇦🇹 ---

@niklasprobst11 Thanks for reaching out! My first thought is that a custom solution may be required using our Protocol Analyzer SDK (perhaps using our Async Serial analyzer as a starting point). > **[Protocol Analyzer SDK | Saleae Support](https://support.saleae.com/saleae-api-and-sdk/protocol-analyzer-sdk)** Our Async Serial analyzer does in fact require a start bit to signify when to begin decoding data for each word being decoded. Is there a set cadence or known delay between transactions for the data you are decoding? For example, how does the receiver align with the incoming data without a start bit? Is there perhaps a clock signal? Hope to learn more!
