Howdy - still struggling to unlock bootloader (or at least I think that’s what’s happening) on the router.
I’ve tried UART on pi, usb-ttl no brand adpater, adafruit usb uart adapter, tried across pi, ubuntu and windows boxes with no joy, still getting the dreaded ERROR: Timeout waiting for ACK/NACK after 'Synch (0x55 0x55)'.
Can i just triple check steps?
Plug in usb - uart device without router attached
Do not plug in power supply to micro usb
Hold down bsl button
Plug in jumpers to header on router
Keep holding down bsl button for 10
Release and launch command, e.g. python ./cc2538-bsl.py -p COM5 -b 9600 -ewv .\CC1352P2_CC2652P_launchpad_router_20210128.hex
No specific baud settings required, default 50000 okay?
Just wanted to add after some testing the compiled router firmware with 20db has been stable for me, and does give give a significant lqi boost (looking at z2m device page).
Hey man I just ordered two routers and want to add a coordinator. I replied to you confirmation email. I assume that email is monitored? [email protected]. Thanks.
Wow received the routers and coordinator. They look great so thanks Tubes.
Only one problem I cannot either of the routers to connect to my ZHA network. I have even tried to use the BSL button re reset at per the instructions. Have tried putting it really close to my Conbee II stick and tried adding them using various other devices. I have debug mode configured.
Sure post some logs on pastebin or paste.Ubuntu.com and I’ll take a look in the morning.
Usually they join the network straight away, and I actually test join each one to make sure they work before shipping. Biggest tip is to make sure ZHA is permitting joins first before plugging in/resetting.
Got mine all setup and running today.
Had a couple minor issues but @tube0013 was quick to walk me through them.
Had to re-flash the coordinator to get it connected to my network. Also had to move some connections around between my switches because my us-16-xg switch wouldn’t connect to it at 100mbps so I had to put it onto my 24 port switch. The cables I was trying to power the routers with had a “base” that was too wide for the etched out area in the case so I wasn’t getting a good connection for powering it up. Swapped to some “skinny” cables and all was good. None of this is a big deal and didn’t detract from the experience at all.
First impression is that everything paired a hell of a lot quicker than it did with the conbeeII stick. Like I’m talking almost instant. Looking at the initial LQI’s were shocking. The conbee stick has a bug in it where all the LQI’s were showing 220+. So when I first looked and was seeing some devices down under 20 it was a mini heart attack. A few hours in I’m seeing the LQI values start to climb.
Long term we’ll see how it goes. I may actually start liking zigbee if this fixes all the issues I’ve had with it in the past.
Yes, I had to re-pair everything. It wasn’t too bad though, with z2m it recognized each device and automatically named them as I had them before. So it was literally just walking around doing the reset procedure on everything. Took a half hour or so.
Planning to grab one when they come back in stock, but I wanted to stick it to the ceiling so I was wondering if there are any STLs for the case or sizes for the board so I can start modeling a new case with a mounting bracket and maybe some internal space to put a PoE to USB extractor inside too.
Thanks very much, I’m past the ack/nack step now.
