A lot of things break if `GNRC_NETIF_FLAGS_HAS_L2ADDR` is not set.
In order to handle router advertisements and auto-configureation,
generate a faux l2 address based on the netdev ID.
This commit fixes the send function of sx126x. The loop that reads the
iolist was not considering the offset. Therefore each iolist snippet was
being written into the first position.
The loop was also setting the payload length to the size of the iolist
snippet. Then the payload was also wrong.
With this commit an iolist is copied sequentially into the framebuffer
and the payload length is set to `iolist_size`
RTC on RTT usually runs at a frequency greater than 1 Hz, so sub-second
precision is available.
Add a function to get the current RTC timestamp together with it's sub-second
component.
setting NETOPT_ENCRYPTION_KEY in device driver was redundant
because it is also done in the ieee802154 netdev driver
and the key is transfered to the hardware in the ieee802154
security implementation
The NETOPT_ADDRESS option of the nrf24l01p_ng driver modified the address of pipe 0 but the main listening
address was designed to be the address of pipe 1.
The Silicon Labs Si705x sensors (Si7050/1/3/4/5) are very similar to the
Si7021 sensors featuring only a temperature sensor and no humidity
sensor. The only difference between the Si705x is the temperature
accuracy of the reading, ranging from +/- 0.1 C in the Si7051 to +/- 1 C
in the Si7050.
This patch adds support for this family of sensors extending the
functionality of the existing si70xx driver. Following the style of
other modules, this implements a pseudomodule per supported chip, adding
si7050, si7051, si7053, si7054 and si7055 pseudomodules.
As a minor change this patch also implements the missing
si70xx_get_serial, si70xx_get_id and si70xx_get_revision functions that
were declared in the si70xx.h header but implemented as private
functions. The si70xx_get_id() may be relevant for the application to
know at run time exactly which version of the hardware is installed.
The updated test running with a Si7051 shows the following output, which
seems consistent with the room temperature conditions during the test.
