BLE Testing functions do not work properly #42534

Closed piotrParf closed 2 years ago

piotrParf commented 2 years ago

I am using Nordic nRF5340DK with Zephyr 2.7.0 LTS SDK. I am using built in j-link and SES(Segger Embedded Studio) to debug. I also use emptyapp from nordic on the application core and example HCI uart from /samples/bluetooth/hci_uart and set CONFIG_BT_CTLR_DTM_HCI=y in prj.conf

I am using nrf testing applications like RSSI Viewer and DTM test demos on Windows and code for nRF5340DK is being build in linux Debian enviroment.

The issue: When I use HCI command LE Transmitter Test the test packets stop transmitting after certain time or packet count(around ~4000). I cant find any workaround to this issue, yet it is needed for Bluetooth hardware testing. The DTM sample app from nRF Connect SDK works as expected but they are not compatible with Bluetooth stack.

To Reproduce Build an Empty Application Core from Nordic, to give control for network core, from their repository. https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf5340/empty_app_core/README.html

Build an HCI-UART application with setting: CONFIG_BT_CTLR_DTM_HCI=y

1.Run SES and load HCI-UART example application to the network core, 2.load empty application core to the network core, 3.connect the UART of nrf5340 to rtt-uart output of NRF5340DK to proceed with attaching HCI-BLE to linux

  1. On linux(debian in my case) run as su : btattach -B /dev/ttyACM1 -S 1000000 -P h4 &
  2. now open the RSSI Viewer application on another Nordic developement kit and start it to watch the BLE radio spectrum.
  3. now on the linux run the hci tool and send command: hcitool -i hci1 cmd 0x08 0x1e 0x02 0x20 0x00 0x00 (HCI_LE_Transmitter_Test [v2] from specification BLE 5.2 Vol 4, Part E) It should start sending packets with PRBS9 at channel 2 with length of 32 bytes, until issuance of the command hcitool -i hci1 cmd 0x08 0x1f (LE_Test_End)

Expected behavior The Bluetooth stack should transmit test packets continuously until receiving LE_Test_End command from HCI interface, yet it spontaneously stops transmitting sooner than the command LE_Test_End.

Additional info The same issue happens when in network core app directly is being called ll_test_tx() function from subsys/bluetooth/controller/ll_sw/nordic/lll/lll_test.c - the packets suddenly stop transmitting after some time.

Since you are using a linux distribution, ensure that Bluetooth Daemon is disabled, i.e. bluetoothd is not running. Do upload the full HCI logs using hcidump tool for futher analysis of the issue.

Also, there are some work in progress related to Direct Test Mode support in Zephyr, please follow https://github.com/zephyrproject-rtos/zephyr/pull/42300

@piotrParf can you please enclose a full btmon trace of the sequence please?

piotrParf commented 2 years ago

I see nothing specia at btmon at the moment. Will investigate tomorrow. Up to today it looks like this.

The problem also occurs when i call ll_test_tx() from firmware on my own not just while connected to hci or so. It was showed made so it could be replicated using HCI- UART example.

Can you help me with formatting this ? :) I am not familiar how to hide/collapse this big chunk of data...

piotrParf commented 2 years ago

From what I found up to date: When running the ll_test_tx(1,20,0,0x01) function from firmware code the packets start transmitting and I am receiving the test packets at other side of the testing enviroment. But at some point(about 2500-4000 packets elapsed) the transmission timer is transmitting with very big period of time. When I measure the period beetwen the interrupts when this "long period starts happening" I receive value of 549762. I am trying out how the timer is being used to trigger the radio sending packets in ll_test and i do not figured it out to the moment...

piotrParf commented 2 years ago

Why in ll_test.c the isr_tx() is written in such a manner ? Especially this fragment ? 

s = radio_tmr_sample_get();
while (t < s) {
    t += SCAN_INT_UNIT_US;
}
/* Setup next Tx */
radio_switch_complete_and_disable();
radio_tmr_start_us(1, t);

What I observed is the issue happens when difference between t and s is so large the while loop takes so long time that the t value is being written to timer in the "past" due to sampling of s far before end of while loop. Because of this radio timer invokes after timer overflows which takes a lot of time.

Isn`t it better to replace the while loop with below code ?

if (t < s){
    t=((((s - t) / SCAN_INT_UNIT_US) + 1) * SCAN_INT_UNIT_US);
}

What do you think @cvinayak? For me it solves the issue of "stopped/very big period of packet sending during test". I do not know how it behaves on other platforms than nrf5340.

cvinayak commented 2 years ago

It is an old implementation, the difference should not be large and the while loop should not iterate too many times such that it is not able to meet the next 625us. But I do see that under rollover of the timer count, the difference will be incorrectly very high.

Your suggestion is good, but do add implementation to handle rollover scenario. Please send a pull request with your changes, we can continue to refine the changes in that PR.

piotrParf commented 2 years ago

should I do pool request on current dev branch or some 2.7 lts ? I am not familiar with working with such a huge system.

cvinayak commented 2 years ago

You should send the pull request to the latest main branch, backports will be generated by github actions when we add labels. For contributing guide, refer to https://docs.zephyrproject.org/latest/contribute/index.html#contribution-workflow

piotrParf commented 2 years ago

I created a pull request. There is another issue which activates this bug. It is in default config definitions of BLE for nrf5340. I observed that radio_tmr_end_get() always returns zero in 2.7 LTS. The defines of radio_tmr_end_capture(void) are changed in radio.c at current main branch. Changing this to current main branch makes proper invocation of radio_tmr_end_capture(). I found that this is related to CONFIG_BT_CTLR_TIFS_HW_SUPPORT=y and CONFIG_BT_CTLR_RADIO_ENABLE_FAST=y not setting up CONFIG_BT_CTLR_TIFS_HW in 2.7 LTS.

dhananjaygj commented 2 years ago

We are also trying to use the DTM functionality of zephyr BLE controller with nRF53. We are facing problem where ll_test_tx works only for maximum 1 second and after that i don't see any RF signals in the analyser. @piotrParf Have you faced a problem like this too? Does your PR (https://github.com/zephyrproject-rtos/zephyr/pull/42866) fix DTM related timer issues? From your last comment, do you mean to say we should enable CONFIG_BT_CTLR_TIFS_HW for nRF53?

piotrParf commented 2 years ago

@dhananjaygj From what I found enabling CONFIG_BT_CTLR_TIFS_HW will work but to make it work you need also to set BT_CTLR_ADVANCED_FEATURES=y otherwise it is not possible to set BT_CTLR_RADIO_ENABLE_FAST=n. But the timers can still rollover and wait a long time without fixing it(it is rare but can). For me that PR fixed the issue because the radio sampling timer handlers are failing(functions radio_tmr_end_capture is written otherway in never versions and radio_tmr_end_get reads zero) with 2.7 on nrf5340 on default configuration with CONFIG_BT_CTLR_TIFS_HW disabled.
