Creating a ble to kettler adapter #420

Open emaayan opened 7 months ago

emaayan commented 7 months ago

Platform your question concerns:

Description: Hi..i have a kettler verso 309 trainer which although does have the ability to use polar T34 i'd like to use my h10 for all the app features, but i'd still want it connect to the trainer, which i think is possible using the 3.5 jack, which just accepts a high and low signals for hr. So i was thinking i could create an esp32 adapter that will pair via ble to h10 (in addition to the existing pair of the app) and for each hr readout will send a high signal to the 3.5 jack. Is such a thing feasible?

Hi @emaayan , I'm not sure I quite understand the issue. H10 can also transmit HR over 5 KHz (just as T34) by enabling GymLink in Flow app settings, see here : https://support.polar.com/en/support/How_to_make_the_most_out_of_H6_and_H7_sensor

I don't have any specific knowledge of Kettler bikes, but you can enable dual-connection and connect to 2 BLE devices at the same time. You would just need to implement BLE Heart Rate Service GATT client on ESP32 side and subscribe to HR notificatons.

thanks, i just found that out, but it would seems that heart rate on the kettler isn't displayed correclty like sometimes it would bounce way up. so now i'm thinking about another thing, where i would attach a garmin ble cadence sensor and create an app that would integrate an the polarh10 and the cadence sensor to on display on my phone. question is will i still be able to uplaod this data to polarflow
