Laird Sentrius RS1XX on TTN - Firmware update failure

Hi,

I have used these units in the past and had no problems updating the firmware via mobile app to use with Cayenne/LPP rather than Laird proprietary payload (f/w 4.5 for obvious duty cycle benefits) . However, had a few units recently and during f/w update process stopped with error -
Updating bootloader - xxx of 1137 Error Task 8 failed: No response to opcode 0x04 OK

It makes the unit unusable - some units seem to respond by pressing down the BLE button for 30 sec and reset but others do not.

Anybody seen this or have an idea how to fix? Laird support contacted but no response.

Thanks

Just a quick update - this issue was experienced when using an ios device running software version 12.3.2 which seems to have been the issue. When I installed the Sentrius Mobile app on an iPhone with ios version 12.3.1 (I assume anything lower will work as well) the units successfully updated their firmware without hanging up. No support from Laird but suspect incompatibility somewhere.

Hi ccsmart,

Laird reached out to me today. No progress yet but will update you as soon as they indicate what the possible underlying cause is.

Hi Brandberg

thank you so much

Very valuable info, thanks! I got nuts trying to update the FW again and again - and guess what, I am running iOS 12.3.1.

Used on older Android for the update which worked fine and can connect from my iPhone normally now.

Same situation for me.

Always block here.
pressing BLE button have no effect.
Who could help me?

The error arrived because, I have try to downgrade the firmware from 4.5 to a another! The apk give you the option, but never do this!!!
Laird help center said me: “there is no way to flash firmware in your side”. But I see the 6 pins inside the battery compartment. I have a hope to update using these pins.
I ask the help center for files… waiting answer now.

So help center say me, "they is no way to flash firmware with 6 pin inside battery compartment.
The sensor will not allow downgrading the firmware over OTA. FW 5.2 and the corresponding update to the mobile app are being released next week. "

So waiting next week…

Hi all,

Laird support indicated to me that they think it is an application issue but no further details than that. Hopefully as kelu28 indicated FW 5.2 with corresponding app will solve the issue. I was fortunate that I did not try to downgrade the FW (did consider it) and then used an older iPhone with older iOS version and was lucky that this worked for me.
I am experiencing incorrect humidity readings on one sensor during my tests and suspect condensation on the sensor. Working on the heater control message to see if I can resolve the issue.
