Sending ECG Data via BLE (EM9301) on MaxRefDes100# HealthSensor Platform #2
Comments
Well a standard BLE packet size is 20 bytes only. If you want to send more, you need to split the buffer contents into those packets of 20 bytes. So if you will receive a packet that contains '\n' you know that's the end of a message. |
Thank you very much for a very prompt reply. You are very kind. |
Just another info regarding BLE: 2 bytes for packet header (type and length), |
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
VM
