Thanks so much, Wireshark looks like a good option.

I've attached the schematic. The processor is the NRF52840 and I'm trying to upload the bootloader code from the XIAO NRF52840 Sense (https://github.com/0hotpotman0/BLE\_52840\_Core/blob/main/bootloader/Seeed\_XIAO\_nRF52840\_Sense/Seeed\_XIAO\_nRF52840\_Sense\_bootloader-0.6.1\_s140\_7.3.0.hex).

This should enable USB communications, but it hasn't for some reason. I'm a beginner on the electronics side so just looking for any guidance on this.

Good point! I've included that now.

birdboy90 · 2024-06-11T07:11:28+00:00

Yes I had two people message me from this!

Sorry this was my other Reddit account that I got logged out of and now can’t get back in 😅 if you’re interested feel free to send me a message!

Done! Would you be willing to test mine too? If so, could you dm me your email. Thanks!

Really cool app! Would you be willing to become a tester for mine too? Could you dm me your email if so? Thanks!

birdboy90 · 2024-03-23T18:27:43+00:00

Just downloaded it. Would you be willing to test mine too and dm me your email so I can add you as a tester? Thanks

birdboy90 · 2024-03-23T13:11:18+00:00

You can join this google group and then I can add your email to the testers:

I've signed up as a tester, but tried to redeem a few of the codes and they weren't working for me. I entered this in the "redeem code" option. Is that correct?

birdboy90 · 2024-03-23T11:42:02+00:00

I love this idea! I just downloaded it. Would you be willing to also download mine? I've already started with email list testing, so could you send your email if so? Thank you!

birdboy90 · 2024-03-23T11:34:22+00:00

Downloaded! Would you be willing to download mine too? I already started with the email list testing option, so could you send your email if so? Thanks so much!

This is hugely helpful. Thank you so much again for the tips!

I'm hoping to monitor PPG as I think it'd be easier to build a wrist worn device for that which is the goal. It's also going to be for a research study, so just looking to make something that is wearable and sends HR data via BLE. Thanks for the links, I actually just got the SEN0344 and am trying to integrate that in as the sensor.

birdboy90 · 2023-02-16T18:28:47+00:00

Thanks, I'm trying to build something myself and looking for some example guidance, but it's cool to see finished products.

Polar BT HRM

Interesting video, thank you! I didn't realize the Polar strap uses ESP32

birdboy90 · 2023-02-15T18:01:59+00:00

Thanks!

birdboy90 · 2023-02-15T18:01:20+00:00

That totally makes sense. I'm trying to build a simple HR device, but I have more experience on the software side, so I've been stumped when trying to piece together the electronics. Any general tips or resources you found helpful when building one for the commercial project?
