New “TextCapture” feature, the SMS Store-And-Forward service you can now enable in your Self-Care!
If you found it inconvenient that you can only receive SMS when your DMR radio is turned on, within repeater/hotspot coverage, and not busy transmitting… Brandmeister has a solution!
Thanks to the hard work of Artem and the Brandmeister beta testing team, you now have the ability to turn on “Text Capture” in your self-care, a feature that will store text messages sent to you if your radio is not reachable at the time of sending, and delay delivery until your RadioID becomes active on the Brandmeister DMR network.
Important Requirement
In order for this feature to work, you need to ensure that your radio sends an acknowledgment of SMS reception back to the BrandMeister network. Otherwise, BrandMeister will keep sending the messages, and you will be spammed!
So before turning on this feature, make sure your radio manufacturer has implemented SMS acknowledgment, and that you have enabled this feature in your codeplug. (We will provide a web-based tool to assist in checking if your radio acknowledges properly. Stay tuned!)
How does it work?
By default, Text Capture is turned off. When someone sends an SMS to your RadioID, if the sender and the recipient are not on the same frequency and timeslot, the message is routed to the Brandmeister master server where your radioID was last seen and sent over the same repeater/hotspot you were using. If your radio gets it, great. If not, it’s lost and it won’t be re-delivered.
Once you turn on the Text Capture feature in your self-care, any data call sent to your radioID (including SMS, IRS, etc.) will be handled by BrandMeister. When an SMS is sent to your RadioID, Brandmeister will capture the message, send an acknowledgment to the sender, attempt delivery to your radio, and wait for it to acknowledge receipt of the SMS. If no acknowledgment is received, Brandmeister will keep sending the message on a regular basis until an acknowledgment is received, for a maximum duration of 7 days. After that, the message will be purged and there is no way to recover it.
Again, it’s important you keep in mind that once the feature is turned on, your radio will only receive data calls initiated by Brandmeister.
Turning Text Capture on and off
- Log on to your BrandMeister self-care page
- At the top right of the page, click on your callsign, and select “Selfcare”
- Toggle the “Text Capture” option ON or OFF:

Hotspots and Repeaters Passwords – Important change on October 1st 2021
Over the past few months, the default password “passw0rd” used for MMDVM, Homebrew, and Kairos connections has been progressively removed from BrandMeister DMR Master Servers. This process will be completed by October 1st 2021.
Below are the details of which devices will be affected with this change, and how to address it.
MMDVM, Homebrew Hotspot users (which includes OpenSpot, Pi-Star, BlueDV, ZumSpot, etc.)
If you have not yet specified a hotspot password in your BrandMeister Selfcare, please do so by following the steps in this article. You will also find explanations on configuring your personalized password for the Openspot, Pi-Star and BlueDV.
MMDVM, Homebrew Repeaters Owners
If you are running a repeater using a 6-digit DMR ID and connected to a BrandMeister Master, and you have not set a password yet, please login to your repeater page and scroll to the bottom of the screen where you will find the “Device Password” field:
Once saved, configure your repeater to use this password when connecting to any BrandMeister Master server.
Dual time-slot MMDVM devices
If you are running a dual-timeslot MMDVM with a 7-digit DMR ID, please follow the steps described in the hotspot section above.
