You're really not making it easy to help you.

Again, we can't read your mind; we can't see what stuff you've got; we can't see what you are doing, and we can't see what results you are getting.

It is up to you to provide clear and complete information.

How do you know what "loud enough" is?

Does nRFConnect show the same RSSI for both of your 2 Tags?

kiranj — Wed, 21 Nov 2018 11:18:15 GMT

I have checked it.rssi also "loud" enough to scan .

RE: ESP32 + NRF52832

awneil — Wed, 21 Nov 2018 10:59:35 GMT

Seriously?

RSSI - the Received Signal Strength Indication.

It's how "loud" the RF signal is - if it's not "loud" enough, then a receiver won't be able to "hear" it.

what do you mean by signal levels??

[quote userid="68004" url="~/f/nordic-q-a/40576/esp32-nrf52832/158356"]I'm also (sic) thinking that ESP32 is not compatible with these tags[/quote]

Nobody else is saying that.

Clearly your unit - which you have still not identified - is compatible, because it manages to see one of your tags!

So you need to investigate your ESP32 code to see where & why it is filtering-out the other tag.

But that, again, has nothing to do with Nordic.

You still haven't answered the question about signal levels.

thanks for your suggestions.I'm also thinking that ESP32 is not compatible with these tags.

[quote userid="2112" url="~/f/nordic-q-a/40576/esp32-nrf52832/158323"]this is an ESP32 issue[/quote]

More specifically, it's most likely an issue with whatever software is running on the ESP32.

[quote userid="2112" url="~/f/nordic-q-a/40576/esp32-nrf52832/158323"]some sort of filtering or whitelist[/quote]

Indeed - which would be a software thing.

As noted above, there might be a signal strength threshold ...

May also be affected by the hardware of the mystery "ble scanner" that kiranj seems so loathe to describe.

Again, none of those things has anything to do with Nordic.

[quote userid="2112" url="~/f/nordic-q-a/40576/esp32-nrf52832/158323"]There is also a possibility there is something wrong with your HW that makes it incompatible with the ESP32 but still works with nRF connect. But this is unlikely[/quote]

Indeed.

So an obvious next step should be for kiranj to try another scanner (or scanners) - there are plenty of apps available to do that.

If other scanners "see" the custom beacon, the conclusion should be obvious...

[quote userid="68004" url="~/f/nordic-q-a/40576/esp32-nrf52832/157942"]esp32 is ... a chip microcontroller[/quote]

Yes - but what is this "ESP32 ble scanner" that you are talking about?

A microcontroller on its own does nothing - it needs both supporting hardware and software to form a functioning product.

RE: ESP32 + NRF52832

run_ar — Wed, 21 Nov 2018 08:40:38 GMT

I have to say I agree with Awneil, that this is an ESP32 issue. I would guess you are doing some sort of filtering or whitelist not compatible with the custom beacon.

More unlikely, There is also a possibility there is something wrong with your HW that makes it incompatible with the ESP32 but still works with nRF connect. But this is unlikely.

So nothing to with Nordic, then.

Remember that this is Nordic's own forum!

esp32 is third party product,on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.

RE: ESP32 + NRF52832

awneil — Mon, 19 Nov 2018 12:23:22 GMT

Yes - but what is it?

Is it a Nordic product?
Is it something that you've built yourself?
Is it some commercial, 3rd-party product?
Or what??

Remember: we can't read your mind, and we can't see what you have on your desk!

hello esp32 ble scanner means its acting as a ble scanner in my case(ESP32 has bluetooth+wifi).and there is no any signal diffrences between them.hope you will get me.

RE: ESP32 + NRF52832

awneil — Mon, 19 Nov 2018 10:55:53 GMT

Does nRFConnect show a significant difference in signal level?

You still haven't answered the 2 questions above ...

RE: ESP32 + NRF52832

kiranj — Mon, 19 Nov 2018 10:34:40 GMT

yes,i have uploaded same firmware on both boards(nrf52832dk and custom made nrf52832 board) but dk board get scanned in esp32 and our board did not....but it is scanning in nrf52832 dk scanner and nrf connect app.but not in esp32.I have compared the raw data packet also it is exactly same for both boards.

Hi Kiranj,

Have you tried to compare the advertisement data on the custom beacon that does not work, with the advertisement data sent from the ibeacon that does work. I guess you are filtering for some UUID or other information that you are missing (or have misconfigured) in the custom beacon.

RE: ESP32 + NRF52832

kiranj — Mon, 19 Nov 2018 03:58:09 GMT

ok ,thanks.

RE: ESP32 + NRF52832

Turbo J — Sat, 17 Nov 2018 13:57:47 GMT

That means your are in the wrong forum, because the problem is obviously on the ESP32. Non-NordicSemi chips are off topic.

RE: ESP32 + NRF52832

awneil — Sat, 17 Nov 2018 10:29:05 GMT

That's just repeating what you've already said - you haven't answered any of the questions; you haven't provided any more information!

What, exactly, is an "ESP32 ble scanner" ?
What have you learned from the fact that your beacon shows up fine in nRFConnect ?

It's your project - so you need to be making the key effort in debugging it!

esp32 not able to scan my tag.I tried to ble scan in esp32 but its not able to scan my tag.its scanning all ble tags except our custom made.

yes it is showing in nrf connect app.

Are you sure that your "custom made beacon" is working?

Is it seen by the Nordic toolbox?
