Re: MicroPython on ESP-WROVER with 4MB of psRAM

Execellent work! But just a note the Pycom W01 module with 4MB pSRAM is in fact already in stock and available for sale:

Same for the L01 (with LoRa). I ordered 10 (minimum for OSM modules) and received on the next day.

Re: ESP32 ADC Calibration curves?

I can give you some preliminary results and plans. (Emphasis on 'preliminary', tests are still on the way so we may find some gotchas later on that may need a change in plans.)Does that help you a bit? Really great to have get some visibility into the ADC correction plans. Thank you for posting thi...

Re: Licensing fees?

If you use Bluetooth you should list your device with the Bluetooth SIG

Re: ESP32 BLE cowork with WIFI

Please note A2DP is a Bluetooth Classic profile, it's not BLE (Bluetooth Low Energy)

BLE itself works well with WiFi but I've not tried Bluetooth Classic/A2DP yet.

Re: BLE implementation

On iOS you can use the Lightblue Explorer app https://itunes.apple.com/us/app/lightblue-explorer-bluetooth-low-energy/id557428110?mt=8 To code your own app in iOS you use CoreBluetooth framework, maybe see this tutorial to get an idea how (ignore the Arduino side, that would be done in the ESP32): h...

Re: BLE transmit power - how to set?

I'm also still looking for some way of changing the TX power level for BLE. Also what is the power level used currently? I see the only mode available is dual Classic/LE (ESP_BT_MODE_BTDM) so does this mean the TX power is dictated by the lowest denominator, +4 dBm, for both LE and Classic? I really...

BLE transmit power - how to set?

Hello everyone,

I'm trying to find how to where the BLE TX power is set and if it's possible to change it.

Is it part of the PHY settings?

Thank you for any pointers.

Re: cannot pair esp32 with android device using

What are you expecting to happen by connecting your phone to the esp32 over Bluetooth LE? There's nothing running there by default to offer any kind of service, it's just doing exactly what you told it to - broadcast advertising packets - nothing more. If you want to connect with your phone and se s...

Re: cannot pair esp32 with android device using

Then how can i pair my mobile device with my esp32 board? Please help me Well you can't pair yet - but also for the BLE_adv demo you don't need to, that's just Bluetooth advertisements (in other words broadcasts). You can set adv_data in the example to the data you want to send, for example: uint8_...

Re: cannot pair esp32 with android device using

That's expected, the ESP-IDF doesn't have functions to support BLE pairing yet.
