[POC] ieee802154_hal: tester PR for #14371 by jia200x · Pull Request #14655 · RIOT-OS/RIOT

Contribution description

This PR is rebased on top of #14371 and add all radios implemented so far for testing the Radio HAL API.
This means:

A POC implementation for AT86RF2xx (doesn't include subghz stuff) 27ae6c3
An (almost) ready to merge implementation for nrf52840 f726f00
A ready to merge implementation for CC2538 ebeb695
A test application for testing these 3 radios. 5aebfa9

Testing procedure

Check the implementations of the radio HAL for each radio. Please focus on the ieee802154_radio_ops_timplementation
Run tests/ieee802154_hal test (for any of this radios).

Test setting channel and TX power with the config_phy command:

2020-08-12 18:24:49,390 #  config_phy
2020-08-12 18:24:49,393 # Usage: config_phy <channel> <tx_pow>

An out of range value for TX power should give an error

Send data between nodes using the txtsnd command.

Usage: txtsnd <long_addr> <len>

It's possible to get the long address with the print_addr command.

Perform CCa with the cca command:

2020-08-12 18:28:57,628 #  cca
2020-08-12 18:28:57,629 # CLEAR
> 2020-08-12 18:28:57,827 #  cca
2020-08-12 18:28:57,828 # CLEAR
> 2020-08-12 18:28:58,157 #  cca
2020-08-12 18:28:58,158 # CLEAR
> 2020-08-12 18:28:58,334 #  cca
2020-08-12 18:28:58,335 # BUSY
> 2020-08-12 18:28:58,473 #  cca
2020-08-12 18:28:58,474 # CLEAR

Change the CCA mode and the threshold with the config_cca command:

config_cca <ed|cs|or|and> [ED threshold]>

Note the ED is in dBm. The ED threshold doesn't affect the Carrier Sense mode (CCA mode 2).

Try different TX modes (CSMA-CA, CCA, direct transmission) using the tx_mode command:

Usage: tx_mode <csma_ca|cca|direct>

Try different RX states (ACK on, ACK disabled, ACK with Frame Pending or Promiscuous mode) with the rx_mode command:

Usage: rx_mode <on|off|pend|promisc>

Use a sniffer to check if the receiver sends ACK. As expected, a radio with Promiscuous Mode will receive all kind of packets with correct FCS.

Use the caps command to get the available caps for a given device:

2020-08-13 13:33:37,385 # caps
2020-08-13 13:33:37,388 #                CAPS

@PeterKietzmann @maribu @benpicco if you all agree, I would like to move the CC2538 commits out of #14371 and move them here. That way #14371 only focus on the API. I can keep rebasing this one.

jia200x · 2020-07-30T09:16:19Z

done!

First test observation:

nrf52840 -> remote-reva : txtsnd <remote-reva addy> 10

nrf52840 hangs, remote-reva crashes
reset both nodes and send a packet the other way around before
nrf52840 will receive the packet
now repeat nrf52840->remote-reva
nrf52840 will indicate that it receive a packet and hang. It is still receive-ready though.

Would be fine to check for the CC2538 MCU here. However, you were talking about the remote-rev% board somewhere, not cc2538dk.

I think we should specify a test procedure according to which we test all combinations of devices

PeterKietzmann · 2020-08-03T10:33:58Z

The issues reported here are fixed with #14672 and #14673.

Suggested change

ack[1] = 0x02;

ack[1] = IEEE802154_FCF_TYPE_ACK;

~~Do we have defines for that?~~

Suggested change

ack[0] = 5;

ack[0] = 5; /* frame length */

We might just initialize that part once and never touch it, should always stay constant.

~~sequence number should be ack[2] ~~

nvm this includes the frame length

yes, this includes frame length. I will add a macro for the magic number

sizeof(ack) would be enough. There are already maces for the rest.

updated to latest changes of #14371

jia200x · 2020-08-05T17:05:17Z

I had to re-implement the set_trx_state function of nrf52840. The radio behaves weird when switching from TX to RX mode without going to DISABLED state (as seen in the ERRATA, Nº 204: "Switching between TX and RX causes unwanted emissions").

I also needed to enable Fast RX-TX transition (this means I had to manually calculate IFS times and reject a transmit request if it doesn't meet the IFS criteria)

benpicco · 2020-08-19T11:09:09Z

So how do we proceed?
Want to make separate PRs for the individual drivers?

jia200x · 2020-08-19T11:11:51Z

I would say so. The CC2420 is in an ok-ish state (I just need to fix some labels and minor stuff). The nrf52840 is also not so far from being in a mergeable state.

The at86rf2xx might need some love.

jia200x · 2020-08-19T11:19:50Z

Rebased. I will leave this PR open as a reference and open implementations for the radios.

jia200x · 2020-10-01T09:34:40Z

since we already have a couple of radios merged with the new Radio HAL API, I think we can close this one.
