Re: WiFi issue with Google Pixel / Android 9, 10

Thanks for the link to your android bug - I've tagged it. My comments weren't intended as any kind of solution - only a test you could run to possibly provide more insight into WHAT is going on. I've found other Android vendors (Samsung especially) all seem to introduce their own bugs/features/behav...

Re: SIM800 TTGO TCALL pppos_client

From the diagram you linked, only Rx & Tx are connected (RTS & CTS are not used).
Are you toggling the PWKEY signal?

From the manual:
PWRKEY should be pulled low at least 1 second and then released to power on/down the module.

Re: WiFi issue with Google Pixel / Android 9, 10

Unfortunately, Pixel does not reconnect to this AP again and choses another network. I'd suggest you re-run this test, but 'forget' all other networks. This will give android no 'other' option, and will increase the likelihood it will follow the AP when it changes channels. I work with a system tha...

Re: My multiple BLE client connection example rarely succeeds

You appear to be using Neil Kolban's ESP32-snippets (you should at least mention this - it's NOT plain esp-idf code). There is a BLE multi-connect example that might help give you some ideas: look in './esp-idf/examples/bluetooth/bluedroid/ble/gattc_multi_connect/main/gattc_multi_connect.c', and loo...

Re: What else can be done during a BLE Scan callback

Consider that a BLE scan involves the scanner hopping between the three 'broadcast channels', dwelling on each channel to listen for broadcasts. What you would need to do is either 'pause' or 'stop' this process, so you can make the radio link to a single device & read data. I'd suggest you abort th...

Bootloader, App, & when NVS is not 'Non-Volatile' Storage

I am using a WIFI OTA bootloader to update my application code. My application code stores configuration & calibration information, in the NVS ('NON VOLATILE' Storage). WIFI requires NVS (not sure why, I think I saw something about storing PHY calibration), so the bootloader needs to initialize the ...

using console uart for 'pass-through'

I have a PC serial port connected to an ESP32 GPIO_1&3, mapped to UART0, which is used for console, bootloading, etc. My ESP32 UART2 is mapped to GPIO16&17, and is connected to a serial device. Under certain conditions, I need to be able to 'switch' the console uart into 'pass-through' mode, for dir...

Re: esp_ble_tx_power_set has no effect

Could you post snapshots of the nRF Connect RSSI graph of your modules, running at PWR_LVL_N12 & PWR_LVL_P9?
That should provide some clue if the modules are somehow at fault.
At least we know you can ignore the -21dBm TxPower in the advertising packet.

Re: esp_ble_tx_power_set has no effect

I'm seeing the same as you describe. I set the 'default' power for advertising using: esp_ble_tx_power_set( ESP_BLE_PWR_TYPE_DEFAULT, ESP_PWR_LVL_P9 ); This function is called prior to starting advertisment, and the flag is set in advertising data to include Tx power. According to esp_ble_power_t de...
