Is it possible increase the size of the Scan Response data for setBeacon()?

[Zed-svg]

For a modified version method of SetBeacon based on the eddystone examples, I am trying to advertise more than 20 bytes for the Scan Response Data from an ESP32 peripheral device to a mobile device. I read that it is possible to send 31 bytes for the scan response data but I am having trouble getting past 20 bytes. After testing around, I found that I can send 20 bytes or less without any issues when I call setServiceData with 20 bytes or less, but anything bigger and it does not send the advertisement data, or at least I do not see it on my phone.

Is there somewhere in the source files that I need to change/set the size of the scan response data?

Code: `void setBeacon() { char beacon_data[31]; uint16_t beconUUID = 0xFEAA;

BLEAdvertisementData oAdvertisementData = BLEAdvertisementData();

oAdvertisementData.setFlags(0x06); // GENERAL_DISC_MODE 0x02 | BR_EDR_NOT_SUPPORTED 0x04 oAdvertisementData.setCompleteServices(BLEUUID(beconUUID)); beacon_data[0] = 0x20; beacon_data[1] = 0x0D; . . .

oAdvertisementData.setServiceData(BLEUUID(beconUUID), std::string(beacon_data, 31));

pAdvertising->setScanResponseData(oAdvertisementData);

}`

Output log:
