Cell signal issues 8.0-rc.11 but OK with 7.0

Firmware
1

Hello Particle forum,

I’m experiencing degraded signal performance on 8.0-rc.11 as compared to 7.0

My setup uses a 1000uF cap inline with a 12V vin signal.

Connection on 7.0 is solid connection 95% of the time in 2 mins

Connection on 8.0-rc.11 is soild connection ~20% of the time.

I am using example 1 from the PublishQueueAsyncRK library

The connection issue on 8.0-rc.11 is much improved if I connect the battery. Unfortunately, our product does not run a battery.

I’m trying to understand what would show this performance difference between two firmware’s running the same software.

Thanks!

Could you try disabling charging in setup() with 0.8.0-rc.11? It might be related to this problem:

Alright! Disabling charging has an improvement. The performance is similar to 7.0 again.

void setup() {
  PMIC().disableCharging(); // Added to improve cell connection in 8.0
	Serial.begin();
  pinMode(ledPin, OUTPUT);
}

Thank you! @rickkas7!
