Thanks Carl!

Using 1.6.0 fixed the problem for me. Have a great vacation!

Hi again!

That sounds good. I'm heading off on holiday for a couple of weeks so if you're facing any pressing issues with this please open a new ticket. Good luck!

Best regards,

Hey Carl,

I totally forgot about the issues in 1.5.x as I ran into them earlier last month. Let me give things a whirl here and I'll reach back out if I'm still struggling.

Thanks!

Hi, Jared!!

Thanks for reaching out. You're absolutely on the right path here, but there are quite a lot of pitfalls with the hci_lpuart unfortunately. Which version of NCS are you using? There are issues with the LPUART driver in 1.5.x so I suggest using master or at least 1.6.0-rc2.

Secondly, have you added the required updates to the board files of the Thingy:91? I've recently did some testing with hci_lpuart on for a quite recent version of the NCS master branch, so you can have a look at the board files I have there as well as this modified version of mqtt_simple. The latter just scans for certain manufacturer data in BLE advertisements. Note as well that the bt_enable functions should be called early in main, to ensure proper synchronization.

Please notify me if you face any issues!

Best regards,
Carl Richard
