Flash firmware with openocd works but there is no advertisement so far

[mowtschan]

I flashed nrf51 device with the firmware apps/openhaystack-alternative/compiled/nrf51_firmware.bin (without any modifications), I used openocd and stlink adapter. Flashing process worked without any issues but there is no advertisement so far, am I missing something?

Keep in mind that the advertisement is set to 5000 msec so you may miss some of the advertisements. For iPhone I saw that the eBeacon app (https://apps.apple.com/es/app/ebeacon-ble-scanner/id730279939) works better than others. Sometimes you may need to wait 20-30 seconds to see the first advertisement though.

I'm using the BlueSee app for macOS which is even better than the iPhone app

[acalatrava]

I installed BlueSee app and I don't see the device but I can see it on eBeacon on iPhone.... In fact I only see 2 devices on BlueSee while eBeacon shows me 6, including my TV... Not sure why

[mowtschan]

Did you install BlueSee app on mac or on iPhone?

[mowtschan]

anyway with BlueSee (on mac) I can exactly see which device is mine (I can see the public key of the device) but with all other tools I cannot see it

[acalatrava]

On Mac. Ok, I forgot to uncheck the filter to show only connectable devices... After some time the device appears:

[mowtschan]

do you have original openhaystack firmware or is it your alternative firmware? is it on nf51 device?

[acalatrava]

This is my alternative firmware just downloaded from releases and flash it on a nRF51 device. The only difference with you is that I flash it using JLink since I don't have STLink. But this is the same file you flash and on the same device....

[acalatrava]

It took some time to appear though, like 30-40 seconds

[mowtschan]

I can successfully build, flash (with stlink) and see advertising (with bluesee app) from example nrf5x-base/apps/s130-beacon:

but still no luck with your firmware :-/

[acalatrava]

Did you try to change the advertising interval?

it works! :-) (for my device nRF51822-QFAA) if I change NRF_CLOCK_LFCLKSRC:

[acalatrava]

Yeah! I thought about that but I couldn’t reply earlier. That’s because your board has no external crystal so you need to use the internal one. You can change this on the board_custom file instead or create a custom board file for your board.

[acalatrava]

Forced to not use an external crystal by default https://github.com/acalatrava/openhaystack-firmware/commit/1524dea6d9c57065447b7b9dec21872a9f07e234
