Hi,

My team has developed an ESP based Hardware having EC200 4G MODEM with inbuilt GPS facility

connected to UART, and an 8Mega Bytes of SPI Flash connected to the external SPI port.

The ESP32 used is ESP32WROOM 32D with 16Megabytes of Flash.

I am receiving bus ticketing data from a handheld device with LPC1768 MCU and ESP32 WROOM 32D

with 16Megabytes of Flash as Bluetooth Transciever.
I am ready to share my source code as PM.

The around 40% of the devices running with this source is having problem of facing abrupt halt while the device is operational.

Can anyone help me in this regard.

Reagds,
G.Muraly

The power supply/LDO/stepdown correct?
can it provide enough power/current?

I assume that you are using classic bluetooth to receive data? If so have you has a look at the data stream? Have you implemented routines to make sure that all the bytes of a single message are transferred and received.
From my experience BT often breaks byte transfers and hence the receiver cannot process them.
