George Oikonomou 8ab0522cec Fix PROP mode channel switching 
If `NETSTACK_CONF_RADIO.set_value(RADIO_PARAM_CHANNEL, ...)` is called when radio is on, it will fail to apply the channel change, because it won't re-send `CMD_PROP_RADIO_DIV_SETUP` and `CMD_PROP_FS`. This commit fixes this condition, by making sure the correct commands are sent to the radio.

cc26xx-cc13xx BLE beacon event issue
 2016-04-18 20:06:33 +01:00
Phil Rhinehart 5d5544151f Fixed bug in cc26xx-cc13xx rf-core. When running BLE in conjunction with ContikiMAC, oscillators were modified from an interrupt state causing occasional bus faults and infinite loops. We now check if BLE is active prior to modifiying the oscillators to avoid these conditions. 2016-04-18 17:17:07 +08:00
Phil Rhinehart 2a07dc0e0a This fixes an event handling issue in the cc26xx BLE driver. Currently, the rf_ble_beacon_process triggers the BLE beacon upon receiving any event, rather than verifying that the event timer has expired. This means that any PROCESS_BROADCAST (e.g. any sensor event) will fire the beacon. This commit adds logic to prevent this. 2016-04-18 17:14:37 +08:00
George Oikonomou d42b1b50e5 Allow the caller to access the entire content of CMDSTA 
When sending a command to the CC13xx/CC25xx RF core, we wait for command completion by checking the LSB of CMDSTA (correctly so). However, in doing so we also zero out the 3 CMDSTA return bytes. For some commands, those bytes contain useful information (e.g. an RSSI value) and are required by the caller.

This problem manifests itself e.g. in PROP mode `channel_clear()`, whereby the caller will always see an RSSI value of 0.

This pull therefore fixes the logic in `rf_core_send_cmd()` to check for command completion by blocking on the CMDSTA result byte without zeroing out the 3 return bytes.

George Oikonomou 54648591ee Explicitly send CMD_ABORT in prop mode before powering down 2015-11-01 22:53:35 +00:00
George Oikonomou f401c7cc60 Save new TX power setting even if the RFC is powered off. 
The current logic attempts to send `CMD_SET_TX_POWER` before saving the new power setting. If `CMD_SET_TX_POWER` fails the power setting will not get saved. As a result, when the RFC is powered off, all attempts to change TX power will fail.

This commit changes this logic to always save the new TX setting as requested by the user. If the RFC is powered up, we apply it immediately. If it is powered down, the new setting will automatically be applied next time we send `CMD_RADIO_SETUP`.

George Oikonomou 55b41863d5 Remove redundant function calls in CC26xx RFC code 
As discussed in #1279, the current CC13xx/CC26xx rf-core code makes some unnecessary power domain-related reads. This commit removes them.

Closes #1279

George Oikonomou 8636a28248 Clear interrupt flags selectively 
As discussed in #1294, every time a CC13xx/CC26xx RF interrupt fires, we clear all interrupt flags unconditionally. This may result in missed events. This patch fixes this bug by clearing only the flag that triggered the interrupt in the first place.

Fixes #1294

Billy Kozak 324d03b53c CC26xx - fully shutdown the rf-core & abort rx op 
Prior to this patch, the ieee radio driver did not explicitly abort
the rx operation or power down the analog components of the radio
prior to shutting down the rf-core.

The result of this was that the rf-core continued to use a lot of
power even while "off".

This patch fixes this problem.

Billy Kozak b71353181d CC26xx - enable correct IRQ in rf_core_cmd_done_en 
Fix for #1229

rf_core_cmd_done_en() was enabling the wrong irq for detecting the
completion of foreground operations. This was causing cc26xx devices
to not wake-up on time when calling lpm_sleep() from transmit().
