Hi @Gordon,
I've just implemented a code that allows to stream data via BLE (in my case to a mobile app developed for a specific task). Idk if it is interesting for you (in terms of adding this part to the original app) or others for private use, in any case, I post it in this post.import { ActivityStatus, AppState} from './state'; declare var NRF: any; //Setto i servizi per preparare la connessione function SetServices(state:AppState){ NRF.setServices({ // activity services 'f8b20001-89ad-4220-8c9f-d81756009f0c': { 'f8b20002-89ad-4220-8c9f-d81756009f0c': { descriptio: 'duration', notify: true, readable: true, value: [state.duration] }, 'f8b20003-89ad-4220-8c9f-d81756009f0c':{ description: 'distance', notify:'true', readable: 'true', value: [state.distance] }, 'f8b20004-89ad-4220-8c9f-d81756009f0c':{ description: 'speed', notify:'true', readable: 'true', value: [state.speed] }, 'f8b20005-89ad-4220-8c9f-d81756009f0c':{ description: 'steps', notify:'true', readable: 'true', value: [state.steps] }, 'f8b20006-89ad-4220-8c9f-d81756009f0c':{ description: 'cadence', notify:'true', readable: 'true', value: [state.cadence] }, }, //HR services 'f8b20007-89ad-4220-8c9f-d81756009f0c': { 'f8b20008-89ad-4220-8c9f-d81756009f0c': { description:'HR', readable: true, notify: true, value : [state.hr], } } }); } function UpdateServices(state: AppState): void { NRF.updateServices({ // activity services 'f8b20001-89ad-4220-8c9f-d81756009f0c': { 'f8b20002-89ad-4220-8c9f-d81756009f0c': { descriptio: 'duration', notify: true, readable: true, value: [state.duration] }, 'f8b20003-89ad-4220-8c9f-d81756009f0c':{ description: 'distance', notify:'true', readable: 'true', value: [state.distance] }, 'f8b20004-89ad-4220-8c9f-d81756009f0c':{ description: 'speed', notify:'true', readable: 'true', value: [state.speed] }, 'f8b20005-89ad-4220-8c9f-d81756009f0c':{ description: 'steps', notify:'true', readable: 'true', value: [state.steps] }, 'f8b20006-89ad-4220-8c9f-d81756009f0c':{ description: 'cadence', notify:'true', readable: 'true', value: [state.cadence] }, }, //HR services 'f8b20007-89ad-4220-8c9f-d81756009f0c': { 'f8b20008-89ad-4220-8c9f-d81756009f0c': { description:'HR', readable: true, notify: true, value : [state.hr], } } }); } export {SetServices,UpdateServices};I added this .ts file to the src folder in my fork of BangleApps and ran using rollup in vs code. Then I took app.js content and with it, I created my own app.
Kind Regards

Thank you, Gordon, solved it!!!

hi @Gordon,
I added this typescript code to banglerun:import { AppState} from './state'; declare var NRF: any; function startStreaming(state:AppState):void{ SetServices(state); } //Setto i servizi per preparare la connessione function SetServices(state:AppState){ NRF.setServices({ // activity services 'f8b20001-89ad-4220-8c9f-d81756009f0c': { 'f8b20002-89ad-4220-8c9f-d81756009f0c': { descriptio: 'duration', notify: true, readable: true, value: [] }, 'f8b20003-89ad-4220-8c9f-d81756009f0c':{ description: 'distance', notify:'true', readable: 'true', value: [0] }, 'f8b20004-89ad-4220-8c9f-d81756009f0c':{ description: 'speed', notify:'true', readable: 'true', value: [0] }, 'f8b20005-89ad-4220-8c9f-d81756009f0c':{ description: 'steps', notify:'true', readable: 'true', value: [0] }, 'f8b20006-89ad-4220-8c9f-d81756009f0c':{ description: 'cadence', notify:'true', readable: 'true', value: [0] }, }, //HR services 'f8b20007-89ad-4220-8c9f-d81756009f0c': { 'f8b20008-89ad-4220-8c9f-d81756009f0c': { description:'HR', readable: true, notify: true, value : [0], } } }); UpdateServices(state); } function UpdateServices(state: AppState): void { NRF.updateServices({ // activity services 'f8b20001-89ad-4220-8c9f-d81756009f0c': { 'f8b20002-89ad-4220-8c9f-d81756009f0c': { descriptio: 'duration', notify: true, readable: true, value: [state.duration] }, 'f8b20003-89ad-4220-8c9f-d81756009f0c':{ description: 'distance', notify:'true', readable: 'true', value: [state.distance] }, 'f8b20004-89ad-4220-8c9f-d81756009f0c':{ description: 'speed', notify:'true', readable: 'true', value: [state.speed] }, 'f8b20005-89ad-4220-8c9f-d81756009f0c':{ description: 'steps', notify:'true', readable: 'true', value: [state.steps] }, 'f8b20006-89ad-4220-8c9f-d81756009f0c':{ description: 'cadence', notify:'true', readable: 'true', value: [state.cadence] }, }, //HR services 'f8b20007-89ad-4220-8c9f-d81756009f0c': { 'f8b20008-89ad-4220-8c9f-d81756009f0c': { description:'HR', readable: true, notify: true, value : [state.hr], } } }); }this code, when the app starts, set services, and when you press start button should start to update value. But when I run the code i obtain this error:

hi,
I accidentally run a code on the Espruino ide on the flash memory, how can I delete that code so that I can reuse the bangle?Thanks in advance

Sorry for returning to this post after months, I'm back on the project, and now I need to modify banglerun to accomplish my task. I added a new src page in the code, where I'd like to establish a BLE connection with my smartphone app. My problem is that I can not run the code because NRF.setService for example gives me an error. Do I have to add some extensions? Do you have some advices to do this ? @Gordon

This project is applicable to stream data to a smartphone, so without using web BLE?
They are custom services, that I read in my app. In that case, they pass to the app measures made by banglerun algorithm. If it can be useful i can share also the C# code that manages connection in my app.
