I am developing a project which uses two ESP32s to transfer Heart rate Variability data that I collect using a small arduino adaptable Electrocardiogram with an analog output. I am using the Client and Sever examples from the ESP32 code library with some attempted tweaks to the Sever code. I am however having issues adding a variable to the code that sends across messages over bluetooth. They come up in the Seiral monitor as squigly lines and cant be interpreted. I am reletively new to using arduino and coding in general. Any help or advice would be appreciated

We need to see everything.
what is the distance between the nodes?
maybe simpler to use WiFi and ESPNOW
Im planning on having it as a wearable but apart from that its only going to be about 2 meters apart maximum. Regarding the ESPNOW, the project is for a school assessment and im trying to save as much money as I can on it and I already had 2 Adafruit ESP32 Feathers.
Do you want to see code or hardware?
Is this a school project?
don't have that specific ESP32 module but I cannot see why ESPNOW would not work on Adafruit ESP32 Feathers
try some of the sample programs from File>Examples>ESP-NOW
distance should be no problem
