Part Number:CC2564B
Hi,
We are using PAN1326B (CC2564B) Panasonic module with Bluetopia version 1.5R2 in one of the product. Bluetooh module interface with MSP430F2418 using 3 wire interface (Rx, TX and GND). during the weekend / continuous 4 to 5 days of testing with couple of device, we found few devices are BLE is not advertise. then we root case it with the debugger and identified, code is struck in the stack, its not at all coming out. So we decided to restart the device once in a 24 hrs; now we don't see this issue.
Since now we are doing the temperature cycling in the chamber -40 deg C to + 85 Deg C at 2 to 3 cycles and holding one hour for -40 and +85 Deg C, then continue to kept for +85 Deg C in 48 to 72 hrs. during this time BLE is not advertisement and triggering to reset the device. This reset leads for our device data log missing. Is there any way to check BLE health using the Bluetooth stack API's ?
Please conform any one has tested with -40 deg C to + 85 Deg C environment conditions ?
How do we address the BLE advertisement stop issue ? without resting the device.
Please suggest / recommend to handle the BLE error handling. what are the error conditions needs to take the actions ?
Note: PAN1326B module and MSP430F2418 microcontroller is used with BGA Package. Bluetooth debug UART signals are not brought out in the PCB; because of board density. As of now BT / BLE combo module we are using only BLE functionality.
Thanks,
Narayanan. S
