Hi Thomas,

 

Could it be that your /usr/bin/python is not the same python you used to install west? i.e. do you have multiple python installations on your system?

 

$ cat `which west` | grep '#!'

 

In my case this yields:

#!/usr/bin/python3

 

which matches my:

 

Found PythonInterp: /usr/bin/python3

I'm just starting up my IAR porting effort again and thought I would just build a simple out of the box project with the standard tools, but I'm immediately running into issues.

I'm on Ubuntu 18.04.4 LTS and have followed https://docs.zephyrproject.org/latest/getting_started/index.html

Hi All,

Here i'm facing the issue even after using the full UART (Tx, Rx, RTS, CTS).
These 4 pins are connected & configured from both (i.MX6UL & nrf52840_pca10056).

Note : nrf52840 chip is flashed with HCI_UART sample app of zephyr. In that i have configured 4 pins and make HWFC enable from nrf5.conf file.

Ans still i'm not facing this issue continuously. Lets say i'm keeping beacon scanning on for 4-5 hours then its working fine. It crashes when i keep it running for 2-3 days.

Thanks,
Mayank

Hi Vinayak

> A btmon log would help identify the reason for disconnection.

I have uploaded the 2 logs here: https://www.dropbox.com/s/d2yurf6nxee9wk0/btmon_logs.zip?dl=0

The Zephyr one has quite a lot at the beginning before I made the connection. Here is one of the disconnect events from the zephyr log file:

< HCI Command: Disconnect (0x01|0x0006) plen 3           #624 [hci0] 292.906310

Yes, that is what it is, apologies:

      LE L2CAP: Connection Parameter Update Request (0x12) ident 2 len 8

Hi Vinayak

I gave it a try this morning with the latest master build of zephyr using the HCI_USB on an nrf52840_pca10059 dongle and I don’t get the errors/timeout issues as I save previously when I tested, however, GATT is unusable from bluetoothctl on linux (BlueZ 5.50). With the zephyr dongle, the device connects, seems to fail a connection parameter updates and disconnects – I am unable to list any details from the GATT server on the remote device (nothing comes through automatically and in the gatt menu, list-attributes seemingly does nothing). In comparison with a non-zephyr (cypress) based USB HCI dongle, it connects and instantly lists the GATT table, the connection parameter update still fails but even minutes later I am still connected to the remote device.

When I tested previously with a UART, it was with flow hardware control wired up to the FTDI chip. If zephyr was set to use it or not I cannot recall (it would have been the default for the HCI_UART example).

Thanks,

Jamie

Hi Carles,

I was assuming it was aimed at both of us, I’m not sure about what hardware they’re using. I’ll give it a try tomorrow with the hardware I have and see if it’s working with the latest branch of zephyr.

Thanks,

Jamie

Hi Vinayak,

> Are you using any host debugger firmware to convert to USB? or using 3v TTL connections to your custom board from nRF52840?

When I tested it, it was using an nRF52840 PCA10059-like board without a 32KHz crystal (RC was selected from zephyr), I also tried on a BL654 DVK with the 32KHz connected and set in zephyr

> For those using USB_UART conversion, I am assuming you are using Segger JLink firmware on the host chip in the nRF52840 DK/dongle. Could you try using the MBED firmware on the host debugger chip?

When I was testing the UART one, I used an FTDI chip so this does not apply. I tested against a BT850 module, which also uses an FTDI with a non-zephyr based HCI module and that worked flawlessly

> Also, please create or refer me to GH issue, so that further discussions can be continued there.

I never created an issue. I haven’t tested in probably about a year now or so.
Thanks,

Jamie
