Confirming all I need to (a) update firmware and (b) update settings for my TT4 is a null modem cable - from it to an older Windows laptop also with a 9-pin serial port? (Clint has some time on his

True, but? WHY??Why reduce the GPS unit's capability for a single character difference? The messages with different Talker IDs could be used by the TT3 & TT4.? They have valid information and are

Hi Guys,? OK, some info. The u-blox r8 receivers are capable of receiving GPS, WAAS, Galileo, Glonass, and BeDou.Since there are only 2 RF frontends, Glonass and BeDou are mutually excluded. With

If you are really interested, you can read the NMEA 0183 documnetation.? I used https://gpsd.gitlab.io/gpsd/NMEA.htmlThe short answer is that the TT3 and TT4 devices look at 2 NMEA 0183 sentences to

So who wants to explain all this to me? No clue what GL, GN, GA GB and why we would need different settings for GPS. David

I don't think a translator is necessary for many of the newer GPS receivers. The output difference for NMEA sentences "we are interested in"? is just the second letter:uBlox

I would be happy if the TT3 just ignored the GLONASS sentences, and just accepted the NMEA sentences. It does not appear that the plethora of inexpensive GPS receivers out there can let you deactivate

I have to admit. I haven't used a TT3 since getting the MTT4B. So only really concerned about the TT4. So I have 2 (or maybe 3) TT4s and the MTT4B (used most). What I am unsure of, is what impact

Yes. Seems more and more GPS units are including GLONASS. Many include others. The prefix I gave correspond to: GP-GPS GL-GLONASS GN-Combined receiver GA-Galileo GB-BeDou From what I have

Robert, Never mind, I just Googled it. You will have to convince Byon to do an upgrade for the TT4. I don't think it is even possible with the TT3.? 73, Allen AF6OF

Robert, Is this a dual-band (NMEA+GLONASS) GPS receiver? 73, Allen AF6OF

I just pulled my MTT4B out again and connected it to a new uBlox M8N GPS module.? Settings: 10Hz update with output at 19200,n,8,1 I see the GPS sentences in a terminal, but the Green LED never

I am not THE moderator, but I am *a* moderator, and I find your posts very interesting. Of course, I fully support your rights to keep and bear ARM's! 73, Allen

Gil, Yours (ST Arm offerings) is one of the best replies I've seen on any group, forum, or old-fashioned email list.?? Since it's OT, I did not know really what kind of response there'd be to my

Robert: I will second that -- the teensy parts are great price/perf computing gizmos in friendly dip formats. Paul S. has done an amazing job not only bringing great hardware to life but writing

Hi Hank: Well, I have only used arms from ST, so can't give a complete perspective. While the core (M0/M3/M4...) is the same for all manufacturers, they add their own peripheral complement, and

If you are asking the general group - I kind of like the Teensy line.* Lots of IO, including DAC.? * High clock rate, low power.? Many of the 3.3V are 5V tolerant. * Good variety of options for

Gil, Which arms do you favor presently?? Just a few of your faves please, together with the main reasons why. Hank __________________________________________________________________ Gil Smith

Gil, It is great to hear from you! I am playing with a slight revision to the MT-AIO, and it uses a switching (5 Volt) regulator, so I expect the new unit to be somewhat more energy efficient. I need
