Same with IPhone it seems

Hi @APOS80 - Are you using Bluetooth SPP or BLE on Android? We have diagnosed a similar issue over here but that is limited to iOS and BLE.

What device are you using? I assume the Torch but just want to be sure.

What measurement rate are you using? The default is 2Hz. If you decrease the measurement rate to 1Hz and disable the GSV sentence does the number of disconnects change?

RTK Torch, iPad Pro M4 11 Inch, BLE, Firmware v1.4, 2Hz.

Lots of disconnects.

I have since disabled most of the NMEA messages.

I noticed that if I turn off the NTRIP client (stop sending corrections to the Torch) it no longer disconnects from bluetooth.

BLE connectivity has changed significantly in the recent RTK Everywhere v2.0 release. We believe this has been fixed.

Other changes pertinent to the BLE connectivity:

• ESP32 Arduino core update to 3.0.7
• BLESerial library update to 2.0.1
• SW Maps update to v3.0

While I was intermittently able to reproduce this issue using RTK Everywhere v1.4, it was not often seen. With the updates in place, I haven't seen a hiccup in a few days worth of testing. Closing for now. Please try v2.0 and let us know if the issue persists.
