History

Updated by Loren Gibson 11 months ago

I too am experiencing this issue with CHIRP daily-20190424 (just updated today), as well as the previous version which was installed on my Ubuntu computer. The error message "Radio refused to send second block 0x1f00" occurs when attempting to download from radio. My UV-5R version is also BFB298.

Unfortunately the "On + 3" message has not been valid for over 5 years. All UV-5R radios report BFB297 (or BFB298) no matter what the "real" firmware version is. And BFB298 has traditionally indicated that the radio was a VHF/220 model (instead of the typical VHF/UHF model).

It appears that these radios are no longer returning the "ext memory" (the area of memory where the power-on message, band limits and squelch threshold settings are) to CHIRP.

Would you try the factory VIP software to see if you can change the power-on message?

Also the How To Report Issues page shows how to find the debug log in the 3 supported operating systems.

Thank you, Jim. Attached is my debug log from my Linux installation.

It appears that the factory VIP software is for Windows, and I don't have access to a Windows box. The URLs I found with software for the UV-5R are http://www.miklor.com/uv5r/UV5R-Software.php and http://www.baofengradio.com/endownload.asp?BigClassName=Programming%20Software&SmallClassName=&page=1. If there is no Linux version of the factory software, I won't be able to run it and attempt to change the power-on message.

You didn't ask for the firmware version (given that powering on with 3 held down is invalid), but I read http://www.miklor.com/uv5r/UV5R-FWRelease.php about how to find the firmware release using Chirp. I'm unable to figure out how to get a settings tab that appears about halfway down the page. If I do a File/New, the two tabs available are Memories and D-STAR.

My model is a UHF/VHF radio.

Gents,

What is the fix? I have 10 new uv-5r5's that report this error in Chirp. Yes, i have the latest build. Even reached out to baefong tech for support. Unfortunately the seller on Amazon is NOT on baefong tech authorized reseller & tech support is NOT supported. All older firware radios programmed perfectly. Just the new ones with (BFB298, power +3), won't program.

"An error has occurred. Radio refused to send second block 0x1f00."

Please assist!
thanks,
McFly255

FYI...
I have programmed 4 brand new Camo uv-5r5's with fireware HN5RV01. Inside sticker is different then the Black\Red uv-5r5's that i just got from amazon.
These ones r the issue.

thanks,
john

I just acquired a second UV-5R, the second one being a 8W "Mirkit Edition" 2019 purchased on Amazon. CHIRP is working fine with this one. The Power-on+3 reports the same BFB298 (which I gather is no longer significant), and in CHIRP, Settings tab -> Other Settings -> Firmware Message 1 is HN5RV01. Firmware Message 2 is 1.

Is HN5RV01 the firmware version? It is the same as that reported above in message #5, but John experiences the problem.

I'm now running CHIRP daily-20190511, and I'm still getting the "refused to send second block" message on my first UV-5R, reported above in message #1.

Would I risk bricking my first UV-5R (the one I can't download from) if I attempted to upload one of the images from my Mirkit edition UV-5R? I suspect this is a poor idea, and I will not attempt this if there aren't assurances that it is safe to do so.

Many thanks,
Loren

I can NOT even download image from radio via Chirp. I immediately get error message once i click OK for initial download. Very frustrating.

Folks,

i'm at a loss on this error. just can NOT find the solution to this error. unless someone has something, i guess i will return to amazon.

8 out of 17 purchased uv-5r5's have error condition. sending back to amazon.
the other 7 programmed just fine. those 7 had firmware (HN5RV01 & 1FB297).

According to the debug.log file, the radio is refusing to report its firmware version to CHIRP.

It seems that most new UV-5R radios have this firmware. Not even the UV5R_W64_VIP software will read it, and fails with "Reading 3 Datablock" then Communication error.

If I hold down 6 and turn on radio it gives code 180531m if this helps?

I have the same exact code when I hold down 6.

And have the same exact problem. Has anyone been able to solve this?

Update: Problem persists in CHIRP daily-20200227 for me.

Updated by Dennis Gonzales 21 days ago

A few days ago I had the same issue, then I tried pressing the connector firmly and it worked.
Firmware Message1: HN5RV01
6+PowerON: 180531
3+PowerON: BFB298

Error occurs if I don't press the connector firmly.
Press the connector firmly on the radio and it will download or upload to the radio.
