decoder web app for Sensor Logger

[mhaberler]

the Sensor Logger app can record BLE advertisements but has a limited set of decoders

I had CC build a web app based on the WASM module just published -- all in-browser, no backend required

branch: https://github.com/mhaberler/decoder/tree/sensorlogger-decoder-webapp

example logfiles from iOS and Android to test yourself are here

were you able to scan BLE advertisements with the app or just decode ?

[mhaberler]

this is strictly a file-based decoder

In Sensor Logger, select Bluetooth devices, record, export log as JSON (sample files under sensorlogs/* were produced this way)
then upload into the app, download the decorated result

WebBLE: I tried in the past and browser support was disappointing - so did not even try here

It might work with Chrome though by now, maybe worth an attempt

[mhaberler]

WebUSB support is a bit better than WebBLE so a dongle-based approach might work better

the nRF sniffer might be a start, and there are several related projects including an open source sniffer rewrite

not elegant but possibly larger footprint

OpenMQTTGateway supports serial already, Theengs Decoder could integrate a flasher of a BLEtoSERIAL configuration, push this to the browser, decode and display the available sensors for the user

[mhaberler]

oh was not aware of that - is that a stock config? like the nodemcuv2-serial ?

that'd be a very cool way to do it and cost next to nothing - you mean like using esp-web-tools or esptool-js?

@Jason2866 now what the world needs is a scriptable version of https://github.com/Jason2866/WebSerial_ESPTool - detect CPU, fetch the right firmware, flash, done

nah, just joking

[mhaberler]

@1technophile can you point me to an OMG setup which you had in mind? I'd want to try the dongle approach
