You need to define the following : (look for them in the code).
// Thresholds for your Power Zones
#define ZONE_1 1 // recovery watts - violet
#define ZONE_2 125 // endurance - blue
#define ZONE_3 160 // tempo - green
#define ZONE_4 210 // threshold - yellow
#define ZONE_5 270 // aerobic - orange
#define ZONE_6 370 // nm - red
//LED control - Number of LEDS in your strip and the GPIO pin connected to the DATA input of the strip.
#define LED_PIN 25
#define NUM_LEDS 30
//Set here the specific address of the powermeter you want use. (You need to do a bluetooth search for it).
#define MY_BLE_ADDRESS "ce:01:fb:7f:d6:b1" //address of the powermeter we want to use
If you want to connect to any available powermeter : replace line on line 25
if (advertisedDevice.haveServiceUUID() && advertisedDevice.isAdvertisingService(serviceUUID) && Scaned_BLE_Address == MY_BLE_ADDRESS ) {
with this :
if (advertisedDevice.haveServiceUUID() && advertisedDevice.isAdvertisingService(serviceUUID) ) {
