Re: Adding predefined BLE service

figured it it out. sort of. With regard to BAS: * add void ble_svc_bas_init(void) signature to ble_svc_bas.h With regard to DIS: * edit CMakeLists.txt in compoenets\bt and add the following to the CONFIG_BT_NIMBLE_ENABLED section: - "host/nimble/nimble/nimble/host/services/dis/include" to the 'APPEN...

Adding predefined BLE service

Hi, I wrote my own Nimble service and now would like to add some 'standardized' services (DIS & BAS) I've noticed that the Nimble stack have these implemented under %IDF_PATH%\components\bt\host\nimble\nimble\nimble\host\services\bas & %IDF_PATH%\components\bt\host\nimble\nimble\nimble\host\services...

MQTT client on AP

Hi, We are about to begin developing a portable WIFi based IoT sensor. Occasionally the sensor wakes up and transfers some data to the cloud. Two use cases should be covered: Where there's WIFI coverage - the device connects as STA and runs MQTT client. This is a straightforward case; and If there's...

pSRAM inquiry

Hi, We would like to integrate pSRAM (ESP-PSRAM32/64) into our ESP32 design. Where can I find datasheet of the device to understand its power consumption? Does it have some kind of 'deep sleep' that retains the data? What is the consumption in such case? How it can be purchased? Is ESP-PSRAM32 the o...

SRAM retention in sleep mode

Hi, I have an application that gets data from I2C sensor, stores it into several KB (>8KB) deep buffer, runs an algorithm on the stored samples and goes idle. This repeates every T ms. In order to reduce the overall power consumption I would like to go to sleep whenever possible. If I understand cor...

ESP32-PICO-D4 advise

Hello, We have developed a wearable product utilizing BLE radio communicating with a mobile phone. Now we plan to move on to a newer device utilizing both BLE + WiFi capabilities and ESP32 is of course a candidate for such a project. I was looking through the Espressif/ESP32 site and noticed the ESP...
