[PATCH 1/9] Complete definitions for all speech traffic frames at MNCC interface
by Andreas Eversberg 11 Mar '14

11 Mar '14

The new definitions are: half rate and AMR Change of definition name for bad frame, because it applies to all types of traffic, not only TCH/F.

[osmo-bts PATCH v2 1/2] misc/sysmobts_misc.c: Read temperature from microcontroller
by Alvaro Neira 10 Mar '14

10 Mar '14

From: Álvaro Neira Ayuso <anayuso(a)sysmocom.de> Add function for requesting the temperature information to the microcontroller. I have added a function that we can extend for requesting more information but in this case we only need to know the temperature. I have added to a microcontroller temperature handling function in the manager for monitoring this information. Signed-off-by: Alvaro Neira Ayuso <anayuso(a)sysmocom.de> --- v2: Removed and fixed the reanilization of the new timer, fixed the function write for consider the value 0 and fixed some leak in the new function for checking the temperature from the uc. src/osmo-bts-sysmo/misc/sysmobts_mgr.c | 42 ++++++++ src/osmo-bts-sysmo/misc/sysmobts_misc.c | 164 +++++++++++++++++++++++++++++++ src/osmo-bts-sysmo/misc/sysmobts_misc.h | 19 ++++ 3 files changed, 225 insertions(+) diff --git a/src/osmo-bts-sysmo/misc/sysmobts_mgr.c b/src/osmo-bts-sysmo/misc/sysmobts_mgr.c index 171f79b..cff15d9 100644 --- a/src/osmo-bts-sysmo/misc/sysmobts_mgr.c +++ b/src/osmo-bts-sysmo/misc/sysmobts_mgr.c @@ -35,6 +35,7 @@ #include <osmocom/core/application.h> #include <osmocom/core/timer.h> #include <osmocom/core/msgb.h> +#include <osmocom/core/serial.h> #include <osmocom/vty/telnet_interface.h> #include <osmocom/vty/logging.h> @@ -53,6 +54,44 @@ void *tall_mgr_ctx;
