Cannot connect to Puck.js after updating Firmware to v1.99 with Windows 10

I have a problem to connect to Puck.js after updating the firmware to 1.99. I tried to connect to the bluetooth device via bluetooth device manager on windows. But I always get an error that I should try it again. When I try to connect to beacon using the NRF connect App it works well.

Do you have any idea? Before the update it worked without any problem.

Have you attempted to flash using a previous version? If so, did full functionality return?

Try this first though:

Was the Puck connected to another BT device? I believe that step of unpairing has to occur, before re-establishing BT after update. Searching for documentation. . . .

EDIT

Ahhh . . . Here it is:

Inside:

see: 'Troubleshooting' find:

beneath the heading: 'I can't see my device any more'

Espruino BLE devices can only accept one incoming connection at a time. When a device is connected to it, it stops advertising and so cannot be connected to until the first device disconnects.

Got it by doing a reset after downgrading the firmware and then upgrading it again.

Glad it's sorted - did you do a reset after upgrading by long-pressing the button when powering it on? That can sometimes help.

Yes, I did. But I did that already before downgrading and it did not work. The only solution was to downgrading to V1.95, doing a reset, upgrading to V1.99 and doing a reset again. Might be a problem that I upgraded from V1.88.

Thanks Mobitech. works great.
From 1.88 to 2.03 is not possible. You need to first upgrade to 1.95 and then 2.03.

From 1.88 to 2.03 is not possible. You need to first upgrade to 1.95 and then 2.03.

...surprise to me... I see nothing mentioned in http://www.espruino.com/Puck.js#firmware-updates

So it must be that before attempting to update directly to 2.03 from 1.88, some application residuals have been left over... Did you do a reset(1) before attempting? But I'm almost certain that not even that is needed.
