I keep on getting ‘COMMUNICATION_ERROR’ every 30 seconds to a minute for about 10 seconds before resuming back to normal.
I am currently powering the Pijuice through the Raspberry Pi rather than the Pijuice because I read it can be powered from either ports. I have tried the micro-usb port too. Power source that is incoming is 5.1v stable.
Out of the box the battery it came with ‘BP7X_1820’ is also not connecting to the Pijuice. It looks perfectly fine as well as the pins on the PCB of the Pijuice - but it still says under battery status NOT_PRESENT.
I have also attached a photo of the information on the GUI when normal.
I am more interested in fixing the stability problem rather than the battery because I do not need the functionality of the battery, as I only need the RTC to work and of course be stable.
I have verified the Pijuice is correctly connected to my Raspberry Pi.
I’ve heard that a lot of times in my life, and I’d say 8/10 times it ends up being a mistake in setup somewhere. Never hurts to get a second pair of eyes over it - and often saves an awful lot of head scratching by everyone.
Thank you Oliver, I have run this command already with no luck, apologies I should have mentioned this. I have also verified it has the latest firmware version.
I also just rubbed the copper on the LiPo battery roughly and now it appears there is connection established to the board and the LiPo battery. I am getting a slow pulsating green light on the PiJuice while the Pi4 is still off.
I can confirm I have connection with the battery and the Pi 4 now. The only thing is I still am getting COMMUNICATION_ERROR popping up frequently.
I am still getting COMMUNICATION_ERROR at the same frequency mentioned earlier.
It looks like the USB-C power to Pi 4, which then powers the Pi Juice from GPIO pins, was the only circumstance where I was getting negative amperage readings. I read that powering the Pi Juice via the GPIO pins (which source power from the power supply via USB-C port) was a method use.
Ok my apologies, I accidentally wrote V instead of A. Correction: -0.9A, -2A, -2.5A*
Based on what you said getting negative current if powering from the Pi 4 itself, this is actually what I am doing, therefore it appears there is nothing wrong with the total voltage and current readings.
This does not explain the communication_error I am still receiving however.
