[kiranj]

hello,ESP32 ble scanner is not scanning my custom made beacon (nrf52832),I have programmed ble_app_beacon apllication in tag and ESP32 is scanning all ibeacon except our custom board tag.please help.thanks.

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.

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.

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??

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

So nothing to with Nordic, then.

Remember that this is Nordic's own forum!

As Turbo Jsaid earlier:

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.

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.
