BLE central_ht only receives 7 notifcations

[1hannah11]

Hi, I've been using the Bluetooth Central_ht sample with a few changes (displaying data differently and changed uuids for my peripheral) and I only receive 7 "notifications" from the notify_func, although I am constantly sending data from the peripheral which is connected. after 7 notifications it doesn't disconnect or unsubscribe it just acts as if its not receiving any data. If i connect a different central to the peripheral I receive constant data as I should be.

I am using a microbit V1 for the BLE peripheral and a Microbit V2 as the BLE central. The code for the peripheral is .ino.

Does any one know why I am encountering this problem?

Changes I made to the Central_ht sample:

//Declaring Temp Service UUIDs
#define BT_UUID_TEMP_SERVICE_VAL 0xccc0 //declares uuid
#define BT_UUID_TEMP_SERVICE
BT_UUID_DECLARE_16(BT_UUID_TEMP_SERVICE_VAL) //creates 16 bit uuid
//Temperature reading characterisatic uuid
#define BT_UUID_CHARACTERISTIC_VAL 0xccc1
#define BT_UUID_TEMP_READING
BT_UUID_DECLARE_16(BT_UUID_CHARACTERISTIC_VAL)

And:
static uint8_t notify_func(struct bt_conn *conn,
struct bt_gatt_subscribe_params *params,
const void *data, uint16_t length)
{

if (!data) {
	printk("[UNSUBSCRIBED]\n");
	params->value_handle = 0U;
	return BT_GATT_ITER_STOP;
}

float rawData = ((float *)data)[0];
double temperature = (float)rawData;

printf("Temperature %gC.\n", temperature);

return BT_GATT_ITER_CONTINUE;

}
