Success compiling v2.0-Beta on Wemos ESP32 board with 18650

[mr-sneezy]

Some feedback to renato and micookie. I followed the new Arduino instructions and installed the advised libraries.

I have a different ESP32 board and are using :
#define RX2 GPIO_NUM_17 // Serial2 standard location on devkit
#define TX2 GPIO_NUM_16 // Serial2 standard location on devkit
#define LED_BUILTIN 22 // usually 2 or 5
#define WIFI_MODE_BUTTON 0 // default is: use the boot button to switch wifi modes

This is compiling fine now and WiFi AP is starting, LED on GPIO22 is working. I connected to the AP and accessed the webserver GUI fine.
Currently I don't have a GPS connected to the UART, I will do that tomorrow and test.

FYI this is my board, which include a 18650 holder and onboard charger.

Adding to my feedback. Seems U-center needed to configure the M8X modules no longer works in Win11 without some messing around.
Is there an alternative ?

[mr-sneezy]

Ok, trying the WLAN connection but have not had any luck yet with U-center. The ESP32 is on the network fine (wifi router reports it's IP & MAC).
The issue seems to be U-center not being able to connect. I get the Connection Error - Can not connect to tcp://192.168.0.212:1818.
I can ping that IP from my Win11 PC though with success.
Of note, my version 24.10 of U-center on Win10 does not have a 'TCP/IP' option under 'receiver - connections', only a 'Network Connection' which is where I set the IP and port...
Is there another way to test or did I miss something in U-center ?

@mr-sneezy - A quick hack is to replace the u-blox command strings here: https://github.com/renatobo/bonogps/blob/main/src/bonogps.cpp#L349. For example, change 1Hz to 20Hz, and 5Hz to 25Hz. This is without changing the GUI, and leaving the 10Hz option.

// set rate of GPS to 5hz
const char UBLOX_INIT_5HZ[] PROGMEM = {0xB5, 0x62, 0x06, 0x08, 0x06, 0x00, 0xC8, 0x00, 0x01, 0x00, 0x01, 0x00, 0xDE, 0x6A};
// set rate of GPS to 10Hz
const char UBLOX_INIT_10HZ[] PROGMEM = {0xB5, 0x62, 0x06, 0x08, 0x06, 0x00, 0x64, 0x00, 0x01, 0x00, 0x01, 0x00, 0x7A, 0x12};
// set rate of GPS to 1Hz
const char UBLOX_INIT_1HZ[] PROGMEM = {0xB5, 0x62, 0x06, 0x08, 0x06, 0x00, 0xE8, 0x03, 0x01, 0x00, 0x01, 0x00, 0x01, 0x39};

Changes to...

// set rate of GPS to 25Hz (from 5Hz)
const char UBLOX_INIT_5HZ[] PROGMEM = {0xB5, 0x62, 0x06, 0x08, 0x06, 0x00, 0x28, 0x00, 0x01, 0x00, 0x01, 0x00, 0x3E, 0xAA};

// set rate of GPS to 20hz (from 1Hz)
const char UBLOX_INIT_1HZ[] PROGMEM = {0xB5, 0x62, 0x06, 0x08, 0x06, 0x00, 0x32, 0x00, 0x01, 0x00, 0x01, 0x00, 0x48, 0xE6};

  for i in range(len(packet)):
    Checksum_L = Checksum_L + packet[i]
    Checksum_H = Checksum_H + Checksum_L

  Checksum_L = Checksum_L & 0xFF
  Checksum_H = Checksum_H & 0xFF

  return [Checksum_L, Checksum_H]

  UBLOX_COMMAND = [0x06, 0x08, 0x06, 0x00, LOW_BYTE, HIGH_BYTE, 0x01, 0x00, 0x01, 0x00]

Checking: did you have "TCP/IP" set to ON in the Connections panel as picture below?

Try this new branch (untested) where 20Hz and 25Hz are added as options, using @micooke ublox binary instructions

[mr-sneezy]

Hi. OK tried the new test branch (thankyou to micookie for the code suggestion). Good result for the speed. I indeed get 20Hz and 25Hz reported in Track Addict on my phone. I see it drop to 19Hz or 24Hz sometimes, but I'm testing from inside my house with no clear sky signal. Good work all.

What I do have to report though is I have a few troubles saving the wanted speed via the webGUI and ESP32 lock-ups. Saving new speed from my phone I could not do it, it results in the ESP32 locking up and requiring a restart. I had more success from using the webGUI from my Win11 PC browser. Saved a higher speed and BTSPP OK there. Changing speed on my phone worked fine though, it was only when saving the changed that I had an issue.
I see some activity in the Arduino serial monitor when that occurs. Should I try capture some of it ?

[mr-sneezy]

[renatobo]

Thank you for testing and reporting back!
That's great news, I'll merge the changes in the new 2.0 branch soon enough; I also want to add a few more define options to change default behavior (right now, the optimal settings are all at 10 Hz).
BTSPP should handle it nicely, while I am concerned about bandwidth on BLE and some testing should be done to at least let users know what has been tested.

The web GUI does not know what type of client device is being used, I am uncertain of the reason for the different behavior. Please share the log from the serial monitor which might help.

I do remember there was an issue in switching between BLE and BTSPP that required restarting the device (current procedure when changing from BTSPP to BLE and vice versa: turn both off, save the config as "other is active" without activating, restart the device, then the other is active), I never took the time to see if newer versions of the library address the issue.

[renatobo]

Some testing with a BK280 unit (very fun gps module) and BLE using Harry Lap Timer

• it works at 20 Hz, with GBS and periodic polling of GSA+GSV even at 1 Hz
• it drops below 20 Hz with errors when refresh rate is 25 Hz but GBS is on
• it works at 25 Hz only when GBS messages are turned off
• it drops ~ 24 Hz with GBS turned off and polling of GSA+GSV at 1 Hz or 5 Hz

Time to bring the 20+25 Hz options in the main branch

[mr-sneezy]

Renato here is a log example from the point of Web GUI connection and a refresh of the screen and rate change (on my phone via the Chrome web browser), the ESP32 heart beat LED stops when this issue occurs and the mode button does not function. A lock-up as far as I can tell.
The thing I see from previous logs that stands out is the 'No more processes' message I saw that a lot last night while testing and trying to save the new rates to the ESP32. Do you want some more logs ?
