Hi @dariobertini ,

Is your device has Proof of possession ? If yes, need to set proof of possession value in application before sending wifi config or any data to device.

hi @khushbushah2302 , thank you for your reply, unfortunately i'm already doing like this.
below my code:
device.setProofOfPossession(pop);
device.provision(ssid, passphrase, new ProvisionListener() {....

hi @khushbushah2302 ,

I get more information about the issue, the exact point where I get this error is on line 142 of Security1.java, in correspondence of the "parseFrom"
private void processStep0Response(byte[] hexData) throws RuntimeException {
try {
if (hexData == null) {
throw new RuntimeException("No response from device");
}
Session.SessionData responseData = Session.SessionData.parseFrom(hexData);

Hi @dariobertini ,
Can you share how device instance is created and then connected with device using BLE ?

Hi @khushbushah2302 ,
we create the device with this code:
ESPProvisionManager provisionManager = ESPProvisionManager.getInstance(this.getContext());
provisionManager.createESPDevice(ESPConstants.TransportType.TRANSPORT_BLE, ESPConstants.SecurityType.SECURITY_1);

after we connect to BLE :
provisionManager.getEspDevice().connectBLEDevice(bleDevice,uuid);

ON ESPConstants.EVENT_DEVICE_CONNECTED event:
this.provisionManager.getEspDevice().setProofOfPossession(pop);
this.provisionManager.getEspDevice().provision(ssid, passphrase, new ProvisionListener() {....

Hi @khushbushah2302 ,

after days of investigation we found out the cause of this issue:
we was using Subscribe to event with POSTING instead of MAIN,
WRONG: @Subscribe(threadMode = ThreadMode.POSTING)
RIGHT: @Subscribe(threadMode = ThreadMode.MAIN)

thank you for your support
