Z2M: Can't pair when flashing 0.1.1.7 #36

Open schumijo opened 7 months ago

Hi

I flashed several LYWSD03MMC last days with version 0.1.1.6 with success. But I just tried to flash a new one with 0.1.1.7 (I didn't notice a new version was available) and I can't pair with Z2M. I tried to remove battery, and also shortcut GND and reset without success

Any idea ?

After 7 seconds, when connecting the “reset” and “gnd” contacts, the thermometer displays “---”? When flashing Zigbee OTA from one version to another, re-registration is not required. That is, it is not necessary.

Nothing happened after 7 seconds. It's not an upgrade but a fresh install

LYWSD03MMC hw B1.4..B2.0 ?

B1.4 I did a lot of tests today without success Now, I managed to go back to bluetooth and I am trying to flash again but I am stuck with "GATT Error Unknown" Still investigating, keep you informed

I cannot recreate the problems described. Groups of the thermometers allocated for testing new firmware work without problems. Here is a group of devices tested together with B1.4 installed on the coldest wall of the house: image The one with the wire sticking out is B1.4, which has been reprogrammed a thousand times in 3 years....

This morning, this group of thermometers was programmed via OTA in the Zigbee&BLE version. image

Others, dozens more thermometers, work in different firmware versions... I'm already tired of updating everything via Zigbee OTA and BLE OTA :)

Hi @pvvx

I finally managed to flash this thermometer with 0.1.1.6 then ota update to 0.1.1.7 I really don't understand what happened with this one. I flashed all my 7 thermometers without problem.

Oh really interesting this version with both BLE and Zigbee. Will test it on one of my LYWSD03MMC

Thank you for your hard work !
