how read characteristic-notification #83

Closed Yury777 closed 3 years ago

Yury777 commented 3 years ago

Hi! I have Thingy:52. I was able to install and configure esp 32-ble2mqtt using the configuration from wiki, but it only scans and transmits characteristics of the "Read/Write" type and does not scan the "Notify"type (temperature, hummidity, pressure, button...). I waited 30 minutes, but no data came in. Please tell me, How can I subscribe to Notify and get their data?

shmuelzon commented 3 years ago

Hey,

Those should work automatically. Every characteristic that supports notifications is automatically registered on and once data is sent from the BLE peripheral, it's published on the MQTT bus.

Which version of this project are you using? Which ESP-IDF version? Do you have anything visible in the logs that might point to an issue? BTW - v0.13.0 is new and uses the latest ESP-IDF, v4.1. As it may still have some issues, you can try v0.12.0 that used ESP-IDF v3.2.2 that was very stable for a long time.

Thanks

App version: v0.13.0 ESP-IDF: v4.3-dev-1901-g178b122c1 here is the log in the monitor: I (12642) BLE2MQTT: Discovered BLE device: da:a6:47:1c:6e:a2 (RSSI: -47), connecting I (15942) BLE2MQTT: Connected to device: da:a6:47:1c:6e:a2, scanning I (16542) BLE2MQTT: Publishing: da:a6:47:1c:6e:a2/Thingy Configuration Service/Thingy Name Characteristic = flokk1 I (16632) BLE2MQTT: Publishing: da:a6:47:1c:6e:a2/Thingy User Interface Service/Thingy LED Characteristic = 1,255,0,0,0 I (16692) BLE2MQTT: Publishing: da:a6:47:1c:6e:a2/Thingy Sound Service/Thingy Sound Configuration Characteristic = 1,1 E (901642) BT_HCI: btu_hcif_hdl_command_complete opcode 0x2005 status 0xc

I tried installing V. 3. 2. 2 on raspberry pi 3b+ but couldn't...

Thanks!

I'm not sure ESP-IDF v3.2.2 can be installed on a Raspberry Pi but, regardless, I suggest switch to v4.1 and not v4.3 as only the former is supported. A lot of time has passed since the publications and the error you posted in the log. It would be interested to know what went on in between. Can you attach the complete log?

shmuelzon commented 3 years ago

Hey, could you please try the latest version of this project (from 3 minutes ago). There was a fix there that might be applicable here as well.

Yury777 commented 3 years ago

I installed idf 4.1 on a raspberry pi 3b+ and downloaded the firmware. MQTT is receiving normal data from the sensors! HURRAY! but when updating the configuration via OTA, it returns an error:

Yeah, I'm using a script that's a part of ESP-IDF to check for the needed Python libraries but the command to fix it isn't really relevant... Try to run:

/home/pi/.espressif/python_env/idf4.1_py2.7_env/bin/python -m pip install paho-mqtt

Thank you!!! everything worked!

shmuelzon commented 3 years ago

Glad to here it works for you. Thanks for the update!
