Can't connect via bluetooth

[yarosman]

Hello. I try to use default ble example with logging to connect JBD-AP21S001-L20S-150A-B, but nothing work

Does your ESP32 report/see other BLE devices around you? Is your ESP able to see the BMS but unable to connect? How old/new is your BMS? Could you provide a photo of the BLE dongle? Do you own an Android device? I could provide some instructions how to do a traffic capture of the data between the Android App and the BMS.

• Does your ESP32 report/see other BLE devices around you?
  Yes, I enable esp32_ble_tracker, bluetooth_proxy and saw other devices in the logs
• Is your ESP able to see the BMS but unable to connect?
  ESP was saw BMS because of

• How old/new is your BMS?
  Manufact.data 10 Jan 2022
• Could you provide a photo of the BLE dongle?
  No, it's under the hood of my battery
• Do you own an Android device? I could provide some instructions how to do a traffic capture of the data between the Android App and the BMS.
  No, I don't have, but I can get it. Can you give me the instruction ?

Could you temporary remove the bluetooth_proxy component and tell me the ESPHome version you are using? A full log would be helpful too.

esphome version = 2022.12.8

[syssi]

Hmm.. we should capture some BLE traffic to get an idea what's different to my implementation. One last idea: May be the ESP is too close or to far away from your BMS. Play around with the distance.

[yarosman]

@syssi Hello. I found the problem. There is some problem with jbd ble dongle, after some time it refuses to accept new connections, it was described in batmon-ha

When I turned off Bluetooth on my phone and turned off/on jbd dongle, after that esp32 was connected to jbd.

Is it correct that switches don't work ?

[syssi]

Yes! The switches aren't implemented yet but they are coming soon!
