Esp32 Pico D4 voltage regulator.

If you want to power your pico d4 with a lithium polymer cell ( 3.7v ) , I have tested a few regulators and this one performs the best so far :-

XC6222D331PR-G

Just in case anyones looking

Thanks

Pico D4 with a Lipo battery

Hi,

Having some troubles with powering a pico d4 with a lipo battery.

Using a ht7333 or ht7833 regulator with a 3.7v lipo battery that I used for the standard esp32 successfully, the pico d4 reports brownouts on boot everytime.

Any ideas how to power with a lipo ?

Thanks

Re: Iphone & BLE disconnects

Hi

Thanks for the message, do you have some code that works and stays connected with the iphone then ?

I have tried loads of things and still getting the disconnect, tried about 5 different esp's while testing so i dont think its the erase flash !

Thanks

Phil

Re: Iphone & BLE disconnects

True, But I am trying to copy the HM-10 BLE module, the iphone just connects to this and works forever, no disconnects So it is possible, could be just a setting in the BLE characteristics I am missing .... If you just connect with the Iphone with the esp32 and then dont send any notifications it st...

Re: Iphone & BLE disconnects

Hi Thanks, i just needed to reboot the iphone, it was being daft, it works now, thanks for all the help. Unfortunately this does exactly the same as the arduino example. If you have 5 minutes spare try sending one byte every 50ms.... it runs for about one minute and then the iphone disconnects with ...

Re: Iphone & BLE disconnects

Nearly :) I worked out the receive, the send variables in the send_indicate I am kinda stuck where to get them from? esp_ble_gatts_send_indicate(mGatts_if, 0, gl_char[1].char_handle, size, (uint8_t*) data, false); Where do you get the mGatts_if variable from ? Something like esp_gatt_if_t gatts_if_f...
