Sik radio: cannot enter bootloader mode, solid green and red LED

Hardware Radios
1

Hello all,

I have some 3DR (mRobotics) Sik radios that have a solid green and red LED. They appear to be “bricked”, I cannot enter bootloader or update the software. The short story is I connect the radio to computer via USB and tried to update the software with Mission Planner. Prior to this, the radio worked. Somewhere during the update process, there seems to have been a failure and now I have a solid green and red LED.

I’ve tried to force bootloader by shorting the ground and CTS pins but that did not work. I tried to use QGC and the error message was “could not find firmware for that board type.” The listed board ID was 81.

Has anyone experienced this or have suggestions?

I’m also talking with 3DR (mRobotics) but haven’t made progress there, yet, and wanted to see if anyone here had ideas.

Thanks!

If you cannot enter to bootloader mode, you can only rewrite the firmware with an USB debug adapter

I don’t think buying this is financially reasonable…

I have a problem with the old 915MHz Sik Radio not pairing, old MP fortunately can update the firmware from 1.9 to 2.2.

After updating successfully, both units are still not paired with the same NetID (blinking Green LED), It is the same usage scenario on 433MHz newer modules, not sure what the issue is, does anyone have the same experience, please share your solution.

these conditions are satisfied.
For two radios to communicate the following must be the same at both ends of the link:
the radio firmware version
the AIR_SPEED
the MIN_FREQ
the MAX_FREQ
the NUM_CHANNELS
the NETID
the ECC setting
the LBT_RSSI setting
the MAX_WINDOW setting

Managed to get the radios working with help from 3DR / mRobotics. They pointed me to a file sik_uploader.py and provided the firmware file for the radio. The python file worked like a charm Thanks to #3DR for the help!

great to hear that. do you have an issue getting “them” to “pair” and talk to each other? My issue now is they do not “talk”.

Not sure what kind of help you’ve got, just to clarify, this is NOT mro nor 3DR radio.

Original products can only be purchased at store.3dr.com or through the official resellers listed on our website.
Any other items are clones, and we are not responsible for their operation or quality.
There are many counterfeits using the 3DR logo, so please be cautious.

These are mRobotic radios.

No issue getting them to pair and talk to each other. This topic is not about pairing radios but there are a number of threads dedicated to that topic.

The radios that Jai.Gay shows do not look like mRobotic units, but the radios I have are from mRobotics.

We found it recently in one of the cupboard. Memory tells us we bought it on 2018/9. We are not very sure back then how 3DR and mRobotics radios look like.

I can tell you by the case, case print, PCB this is NOT mRo NOR 3DR radio.

Not sure where you have bought it, but this in not our product.

Just to clarify, by ‘clones’ I mean radios that have mRo or 3DR markings but were not manufactured by the OEM.

These ones could be from any other brand, but the radios in the photo are not mRo radios.
mRo/3DR shields are branded, the cases are branded and screwed (not glued).
The marking is on the back of the PCB (not top corner), and the PCB also contains the logo.
