RNode_Firmware 1.82 for Lora32 v.3

[yuz86]

Hi. In the latest software release v.1.82 for Heltec Lora32 v.3 I found a bug, after flashing and trying to pair via bluetooth with a smartphone, the digital pairing code does not appear on the module display. When giving a command from the Web programmer window the code is displayed, I managed to dock the module with the new firmware, but in the field it will be impossible to do it. If possible, please correct the latest version of the software. With respect and gratitude for your work!

Did you put the RNode in to pairing mode? How did you do it?

[yuz86]

In the latest firmware versions (1.82 and 1.75) it is possible only through a connected computer via USB, by sending a command from the flasher window, and without it the board does not issue a pairing code in these firmware. In previous versions everything worked and the code was issued.

Also the battery level board lora32 v.3.2 is always displayed empty, what can be done in this case?

[cobraPA]

Ah, you left out it was a v3.2... The 3.2 has a modified battery circuit, I don't think any of the RNode firmware supports it yet.
Do you know what previous version of code you had on the RNode? Mark's firmware has always required setting a pairing enable. Normally by USB, but I think you can also fast press the button to enable (I have not tried that myself.)

No manipulation with the buttons did not help, the right button restarts the module, and the left button only controls turning bluetooth on and off. I sent a pairing command from my computer and successfully docked with my smartphone, after which I have already reflashed several times with different firmware versions and the phone successfully connects to the module.
With the battery can be something to do, maybe some resistors to add or additional wires solder between the necessary contacts, I have no data on the pinout and on which of the pins comes the voltage from the battery to measure its charge level?.

I've had similar issues with a T Beam

You hold the left (USR) button for 5+ seconds and release to put it into pairing mode. Does that not work?

[markqvist]

In v1.82, the pairing code should appear immediately on the screen after putting the device into pairing mode.

[yuz86]

Pressing and holding the left button simply turns off the screen, holding it again turns it on, I have tried it many times, from the phone it is absolutely impossible to make the module on firmware 1.82 and 1.75 to issue a pairing code, it can be done only from the computer from the flasher window. On the previous firmware 1.81 the code is issued immediately without any problems. My board is really new modification v.3.2 and now from China they send all boards of this version.

[markqvist]

You hold it for 5+ seconds. Press down the button. Count to 6 in your head. Release it.

If you do that, does the code still not display on the screen?

[yuz86]

Yes, indeed if I hold the button for more than 6-8 seconds and then release it the module starts to display the pairing code. Up to 5 seconds it turns off the screen. I think this information should be put in the firmware description or on the Web-flesher page.
Thank you very much for the detailed explanation, we have ordered some more Lora modules from China, one of which will be installed with a bidirectional signal amplifier on the external antenna to test the coverage area.
