You can query the active connector info:
- DMR: call the "Connector query DMR ID" with a PTT press
(by default it's ID is 9998).
- C4FM: DTMF code *D
- D-STAR: call " I" (7 spaces and an I)
- Added profile change support to connectors.
You can query the active profile number:
- DMR: call the "Profile query/change base DMR ID" with a PTT
press (by default it's ID is 9000).
- C4FM: DTMF code *A
- D-STAR: call " P" (7 spaces and an P)
To change the active profile:
- DMR: call the "Profile query/change base DMR ID" with the new
profile number appended to the base ID. Example: you want
to switch to profile 4, and your query/change base DMR ID
is 9000: you have to call 90004 with a short PTT press.
- C4FM: DTMF code *A4 (*A and the new profile number)
- D-STAR: call " 4" (7 spaces and the new profile number)

- Server is now remembered when switching between Homebrew and
MMDVM protocol modes.

server is used when the main server can't be connected in the given

- Status page has been restructured.

version there's no need to manually clear the browser cache as
browsers should be able to decide whether the web interface needs
a full refresh.
- Homebrew MMDVM protocol mode fixes.
- Fixed FCS and YSFReflector no keepalive sent issue.
- Fixes for Chinese radio stuttering and dropouts.
0087: - Added option for transmitting RX confirmation for received C4FM
calls from the modem. This will make the C4FM radio to emit a beep.
0086: - Connectors now reconnect much quicker. Connector switching got
- Sending a group message in UDP/Chinese now always succeeds (group
data calls are unconfirmed).
- Improvements in D-STAR lost packet handling.
- Disabling DMR in-band data sending to modem now does not disable
in-band data sending to the network.
0085: - Added option for removing DMR in-band GPS pos. and talker alias data
from modem stream. Some radios (like the Hytera PD365) doesn't seem
to handle in-band data correctly, so in-band data should be removed
from the stream sent to them.
- Added support for interrupting ongoing calls when doing a quick call.
This is possible because of the new Homebrew protocol command RPTINTR.
Note that this command is only available in the latest Brandmeister
version, so your server may not support it yet.
0084: - Added support for config profiles.
- Added support for exporting and importing profile config files.

to this version, but if you downgrade, your configuration will be
reset to defaults.
- Added MMDVM protocol mode to the Homebrew connector which can be
used to connect to DMRplus for TS1 and TS2 support. DMRplus dongle
protocol will be removed in a later version as the MMDVM protocol
allows more robust packet loss handling.
- Added quick call feature to the web interface. This currently works
only with the Homebrew connector.
- openSPOT now allows in-call GPS data and talker alias to pass.
- Added support for cross mode talker alias handling.
- Added force talker alias to network option to the web
interface. If it's set, this alias will be sent instead of the DMR
radio's alias to the network. You can also use this if your radio does
not support talker alias sending.
- Now all callsigns are converted to uppercase, as D-STAR servers
reject connections with lowercase callsigns.
- Added option to adjust Homebrew advanced missing packet handling.
This is turned on by default. If you have network connection issues
with high packet loss, advanced missing packet handling gives better
audio recreation of the missing frames.
- Fixed Homebrew data/SMS send.
- Fixed that default DMR ID is not used for unparseable C4FM callsigns.
- Removed spin.js.
0077: - Added support for transmitting CW ID.

openSPOT will only start transmitting when the RSSI level is below
- Changed the string "password" to "server password" at Homebrew
settings on the web interface.
0072: - Increased max. length of DMR ID on the web interface to be compatible
with Brandmeister's new SSID feature (you can add an SSID from 0 to 99
to your DMR ID, for ex. DMR ID 2161005 and SSID 43, then enter
216100543 as your DMR ID).
- Changed sharkrf.com reflector database domain zone.
- Fixes for adding and deleting custom servers on the web interface.
0071: - Fixed Homebrew connector reroute ID overwrite when auto connect is
0070: - Fixed REF/XRF, DCS/XLX reflector change issue.

auto connect ID if rerouting is not turned off.

using the radio.

0066: - Added room descriptions to FCS server list.

to zero after this firmware upgrade.
- "connected to" field is now updated on both call start and call end.
- Fixed "connected to" display in cross modem mode.

0061: - DPlus/DExtra fixes.
- Added HTTP CORS headers.
0060: - Added DMR SMS chat page.
- Added support for sending and receiving DMR SMS messages to/from
the network (currently supported connectors: Homebrew, SRF IP Conn.
