I used the bluetooth low energy app for esp32, but I can't read data from esp32, sending data from esp32. however, the application cannot catch it. Can you help me?

Hello Viktor,

I want to design wearable ECG(Full ECG, not only heart rate)+SpO2+Temperature monitor from scratch. Could you suggest if I should go with ESP32 Microcontroller for my project or STM32 is best for wearable device projects? If I succeed my company want to go for FDA approval of the device also, so it has to most accurate. Also my senior may need to add Machine Learning algorithms too, to be implemented on/in Microcontroller only.
I will appreciate all your help and advice.Your YouTube videos are really BIG BIG help.

Thanks and Regards..

Hello Viktor,

I saw your tutorial video on YouTube.
STM32 and Android tutorial - ECG (single lead, 2 and 3 electrode configuration)
It is really good. I thank you for that.

We are trying to develop a multi sensor wearable device using MaxRefDes100# and we are struggling with sending ECG data to mobile device via on chip BLE (EM9301). The onboard Microcontroller is Max32620 and ECG sensor is Max30003 (and other sensors).

Here are the useful links to the device

We need to send almost 400 bytes only for ECG, but we are unable to change the default byte size which is 33 bytes I think.

We will be really thankful if you could pls help in any way.

Thanks and Regards
